New Panacol epoxy adhesive for bonding magnets

Structalit® 5858 is a modified, one-component epoxy resin adhesive that was developed specifically for bonding magnets into electric motors. Its high bond strength and impact resistance ensures reliable bonding.

Structalit® 5858 can be cured thermally in a conventional oven at temperatures from 100°C. It is also possible to use induction curing for faster polymerization and shorter curing cycles. The adhesive requires storage between 0-10°C, but its stable viscosity and reactivity allow it to be processed on the line at ambient temperature for up to seven days. 

The Structalit® 5858 was developed by Panacol to expand its line of adhesives for electric motor assembly.  After proper curing, Structalit® 5858 generates excellent adhesion to metals. With bond strength over 34 MPa on steel and aluminum, this adhesive creates reliable and high-strength bonds.  Even at temperatures above 100°C, Structalit® 5858 continues to exhibit excellent superior bond strength, ensuring consistent performance during thermal stress. The high impact strength of this modified epoxy ensures that bonded components will not loosen or separate from operational vibration or external forces. Structalit® 5858 is particularly suitable for bonding magnets, such as the connection of half-shell magnets in stators, or permanent magnets on rotors.

New biocompatible UV adhesive for soft plastics 

Panacol has developed a new plastic bonder that is certified to USP Class VI biocompatibility standards for medical device assembly applications. Vitralit® UV 7030 features high elongation at break, excellent adhesion to difficult-to-bond plastics, and rapid curing under UV light.

The various material selections and pairings of flexible tubing and rigid connectors often create significant assembly challenges in high volume production.  Materials used to create infusion lines, catheters, and similar medical devices may include TPU, TPE, PEN, polyamides, Pebax®, polycarbonate, ABS and PEEK. These thermoplastics and thermoplastic elastomers provide many desirable properties, but some combinations can be difficult to bond. After assembly, these materials are challenged by torsional stresses at the points of transition between the soft tubing and the hard connector.  Panacol developed the adhesive Vitralit® UV 7030 to specifically address these complex issues.

Vitralit® UV 7030 is a one-component, solvent-free UV curable acrylic adhesive.  It can be cured with light energy in the broad UV-A spectrum, or with LED systems that produce either 365 or 405 nm wavelength. This adhesive cures in seconds at layer thicknesses of a few 100 µm, ensuring high bond strength immediately after UV exposure. A key feature of Vitralit® UV 7030 is its high elongation at break, >250%, combined with good tensile strength. When exposed to black light, Vitralit® UV 7030 fluoresces, which enables visual process control. Vitralit® UV 7030 is certified to USP Class VI standards and suitable for typical sterilization processes including gamma, EtO and autoclave.

Panacol introduces new reworkable underfill adhesive

Panacol has developed a new reworkable underfill for consumer electronics. The reworkability and fluorescence despite its black color of the new Structalit® 5751 adhesive allows manufacturers to reduce both manufacturing costs and environmental impact by reusing electronic components mounted on PCBs.  

Underfills serve the purpose of equalizing stresses between chip and substrate. Chips are attached directly to the interconnection points without intermediate elements. Stresses arise at the solder bumps when the electronic modules are heated and cooled during operation due to the different coefficients of thermal expansion of the substrates. Underfill technology was developed to counteract these mechanical influences.

Structalit® 5751 is a black, heat-curing, resin-based epoxy adhesive characterized by its low viscosity and linear flow behavior. These properties enable precise application. In addition to classic contact dispensing by means of a dispenser, the uncured properties of Structalit® 5751 also allow contactless dispensing for fast and precise placement of the adhesive. This underfill is has a low ion content and is ideally suited for electronic component packaging.

A typical feature of adhesives on PCBs is their black coloring, which is used to obscure proprietary features and for optical inspection. Optical measurement of an underfill is a common method used in the manufacturing process by manufacturers. But due to the dark chip, shallow layer thickness of the black adhesive and tight gap between the chip and the substrate, optical measurement is often difficult. Panacol has addressed this problem by incorporating an additional yellow shimmering fluorescence to the black coloration of Structalit® 5751. It can be stimulated by short wavelength light of <365nm. This makes it even easier for manufacturers to perform final inspections and speeds up production processes.

In addition to the performance and optical inspection capability of Structalit® 5751, Panacol offers another important property with its newly developed underfill: reworkability. This provides the ability to re-process or repair products after assembly. For manufacturers of electronic components, this challenge is becoming increasingly important as legislation and environmental associations push for the minimization of electronic waste. One starting point of this sustainable strategy is the reworkability and repairability of individual modules on printed circuit boards to counteract the scrapping of a complete component or module.

Structalit® 5751 can be strategically softened at specific adhesion points by applying temperatures above its glass transition temperature range of 150°C. The product becomes reworkable only when this critical temperature threshold is reached.  The reworkability temperature does not reduce the protective function of the Structalit® 5751 during typical PCB processing.  It withstands temperatures associated with reflow soldering and additional thermal curing cycles.

The current global shortage of chips and general electronic components in the automotive and consumer electronics sectors further highlights the significance of being able to reuse components.  Reuse of components is not only a benefit to the environment, it has become essential to sustain current production processes due to supply chain shortages.

New epoxy adhesives cure at 60°C

Panacol has developed a range of new one component epoxy adhesives that cure at very low temperatures. These new adhesives were developed specifically for electronics applications and adhere very well to substrates with low surface energy.

With the adhesives Structalit® 5511, 5521 and 5531, a range of adhesives has been developed that exhibit a unique set of physical properties after reaching full cure. This permits optimizing the adhesive with various component geometries, substrates, and operating functions.  

All three adhesives are single-component, epoxy resin-based adhesives and cure at just 60°C, making them particularly suitable for temperature-sensitive electronic components. Curing at higher temperatures will accelerate cure time and add additional strength to the bond. 

Structalit® 5511 features a particularly low ionic content and is therefore especially suitable for use in electronics. Combining a high Young's modulus with an elongation at break of more than 8%, it ensures high adhesion to many substrates with additional shock and vibration resistance.

Structalit® 5521 is softer and more flexible after curing, allowing the adhesive to better compensate for stresses between substrates. Due to its very low modulus of elasticity, this adhesive is very well suited for potting or for the application of thicker adhesive layers.

As the third adhesive of the new epoxy technology, Structalit® 5531 has an extraordinary low coefficient of thermal expansion (CTE), yet is flexible enough to withstand drop and vibration tests. The incorporation of filler particles gives the adhesive extremely high resistance to mechanical and chemical influences.  

These Structalit® adhesives from Panacol generate very high bond strength with materials typically used in the electronics industry. They can also adhere very well to LCP (liquid crystal polymer) and other high-tech plastics with low surface energy. All three adhesives possess high purity and low ion content which complies with international standards for electronic and microelectronic component assembly.

Panacol introduces new high-performance frame-and-fill adhesives

Panacol has developed a new range of high-performance adhesives for frame-and-fill applications on printed circuit boards. 

Frame-and-fill processes are used to protect highly complex areas on electronic circuit boards. In the first step, a highly viscous barrier – the so-called frame – is applied. In the next step, this area is quickly filled with lower viscosity filler material – the fill. With this precise process, areas on the circuit board can be protected from mechanical impact factors.The combination of frame-and-fill materials allows the application of minimum barrier and potting heights and cures to a homogeneous coating. Panacol's new frame-and-fill adhesives are perfectly matched so that the frame and fill areas can be optimally dispensed wet-on-wet without the still-liquid adhesives leading to undesired flowing on the PCB.

The frame material, Structalit® 5704, is a black, thermally curable and single-component epoxy. This frame and glob top compound features excellent bead stability and high glass transition temperature of 150°C up to 190°C, depending on the curing parameters and the layer thicknesses. When using Structalit® 5704, no bleeding effects occur. Due to the very low ion content of less than 20 ppm, Structalit® 5704 is suitable for chip encapsulation on electronic circuit boards. 

As a fill material, Panacol has developed a range of adhesives with different rheological properties. The adhesives Structalit® 5717 to Structalit® 5721 are formulated with optimized flow behavior, so that the adhesives can be used on various chip and bonding wire geometries due to the differently adjusted viscosities. Since the fills have the same chemical base as the frame material, the excellent physical and chemical properties of high glass transition range, ion purity, temperature stability and minimal shrinkage behavior are also found in the fillls. 

Once cured, Structalit® 5704 and the matching fill of the Structalit® 5717-5721 series form a black, opaque and scratch-resistant coating. These properties together with a temperature resistance of up to 200°C ensure maximum reliability.

Smart system solution for needle bonding

A main field of application for adhesives in medical systems is needle bonding and syringe assembly in high volume production. Optimally matched processes are essential for reliable bonding. Panacol, Hönle and bdtronic partner to ensure that precise adhesive dosing, capillary flow and curing in seconds with UV light work hand in hand.

As the needles are produced in large quantities rapid and reliable bonding is essential. In addition to their mechanical bond strength, the adhesives used must allow high-precision production and permanent joining and must withstand various sterilization methods. Panacol’s UV curable Vitralit® adhesives exactly meet these requirements.  Vitralit® adhesives are available in various viscosity ranges to perfectly fit the design of the needle hub and fill the gap between the hub and the needle. The material of the hub and needle also affects the choice of the adhesive: Many adhesives are UV-curing, which requires the use of transparent and UV-permeable materials. For materials that block UV light, such as polycarbonates, long-wave LED curable adhesives are recommended.

All Vitralit® adhesives recommended for needle bonding are solvent-free and certified USP Class VI and/or ISO 10993 for use in medical equipment. In addition, high needle extraction forces were measured with all needle bonding adhesives even after several sterilization cycles. For visual quality inspection, fluorescent versions of our medical grade adhesives are also available. 

The choice of the adhesives requires a matching dispensing system for reliable and precise dispensing in a rapid production environment.

The high quality demands required for medical devices, as this needle bonding application, confirms the choice for bdtronic’s volumetric dispensing equipment. With the mini-dis solution provided by bdtronic, dispensing in microliter range is made easy, regardless of the adhesive viscosity. Thanks to the continuous volumetric dispensing, the dispensing is pulsation free ensuring optimal process speed, repeatability and accuracy.

Finally, the choice of the UV curing equipment depends on the adhesive and the wavelength which triggers polymerization. For needle bonding with Vitralit® products you can use either UV-A or visible LED light. 

Due to a special LED assembly and an own optimized electric power supply, Hönle LED Powerline LC guarantees a high-intensive irradiation for fastest curing and shortest cycle times. In addition, the irradiation time can be selected in a range of 0.01 – 99.99 sec and thus precisely adapted to the process requirements.

Hönle LED Powerline heads have a compact design for an easy integration into any production line. The high-intensive, water-cooled LED-UV is suitable for clean room operation.

Panacol and Hönle develop new system solution for filament winding processes

With the newly developed Vitralit® UD 1405 adhesive, Panacol has created an innovative adhesive system for fibre and filament winding. For high efficiency, Vitralit® UD 1405 can be applied during the winding process and immediately cured with high intensity LED curing systems from Dr. Hönle AG. This innovative winding process is extremely space and time-saving, and can produce significant processing cost savings.

Vitralit® UD 1405 can be used to wrap components such as hybrid rotor shafts for electric motors and high-voltage surge arresters. The adhesive-coated fibre-reinforced windings can be then be quickly cured with UV/visible light. This adhesive and curing system is ideal for Carbon or Glass Fibre filament winding associated with Carbon Fibre Reinforced Polymer (CFRP) or Glass Fibre Reinforced Polymer (GFRP) manufacturing processes. 

Panacol’s Vitralit® UD 1405 is a transparent, solvent-free, one-component epoxy. Due to its low viscosity, Vitralit® UD 1405 has very good wetting properties. It can be cured in seconds by irradiation with UV (365nm) or Visible (405nm) light wavelengths. Depending on the fibre material and the wavelength used, layer thicknesses of several millimetres can be achieved exclusively by UV/Visible light curing. This epoxy can also be thermally cured after UV exposure to ensure that a complete cure is secured in areas shadowed from the UV light. For example, fibres or filaments can first be pulled through an adhesive bath, then wound onto the rotor or respective cylinder, and cured with UV or visible light. A secondary thermal cure will ensure that the layers of coated windings below the surface become fully cured.

For the most efficient UV curing system for fibre and filament winding processes, the LED Powerline AC/IC 820 HP from UV specialist Hönle is the perfect choice. With intensities of up to 16,000 mW/cm², this LED system ensures very fast curing. Its light emission window is available in two standard sizes, 82 mm x 20 mm and 122 mm x 20 mm, which can be extended without gaps by stringing together multiple modules. When developing the LED Powerline AC/IC 820 HP, special attention was paid to a slim design. This makes it ideal for use where space is at a premium, such as automated winding equipment. 

The powerful LED Powerline AC/IC 820 HP can be powered and controlled using the optionally available LED powerdrive IC as a plug&play solution, or by using a customer supplied external power supply and PLC. This makes the LED Powerline an ideal solution for integrating high power LED curing systems into automated assembly processes.

After curing, Vitralit® UD 1405 is electrically insulating, shows minimal shrinkage and remains resistant at temperatures from -40° to 180°C. A glass transition temperature of over 130°C ensures reliable performance even under dynamic load at elevated temperatures.

New Optically Clear Adhesive

Panacol developed a new optically clear adhesive: Vitralit® 50004. The new adhesive is a one-component uv curable acrylic adhesive with ultra-low viscosity, which is used for bonding displays and laminating optics.

Vitralit® 50004 adheres specifically to a variety of substrates including coated glass, PET and other plastics and films. It possesses a very low viscosity that facilitates fast filling of cavities without air entrapment. The adhesives cures quickly with minimal shrinkage for less residual stress between substrates.

Large-surface bonding or lamination of displays can be optimized by using Hoenle’s high-performance and energy efficient LED Spot 100 curing system which is perfectly matched to the photoinitiators of Vitralit® 50004.The alignment of the LEDs of the Spot 100 ensures high intensity and homogeneous light distribution. The LED Spot 100 heads can be mounted together without gaps to match the size of the display being bonded.

Once cured, Vitralit® 50004 is very soft. Thermal stresses between dissimilar substrates can be neutralized without causing delamination. It’s high degree of flexibility enhances performance through repeated thermal excursions. The cured adhesive is optically clear and non-yellowing with excellent light transmission.

New Panacol Adhesives Cure With UV/moisture

Panacol developed a variety of new adhesive products with low ion content which cure with uv light and moisture. These products were specially formulated for applications in the electronics and consumer electronics industry, where heat sensitive parts must be assembled.

Vitralit® UD 8050 is a one-component acrylic adhesive, which can be used as an encapsulant to protect electronic components on PCBs. Vitralit® UD 8050 can be cured with uv or visible light. Moisture postcuring ensures full cure in shadowed areas or deeper layers of the adhesive, which cannot be reached by light.

For specific requirements several versions of the adhesive are available: Vitralit® UD 8050 MV F allows enhanced flow control and focused dispensing on each component thanks to its shear-thinning behavior. Its low ion content prevents cor-rosion on electronic components. For superior process control Vitralit® UD 8050 MV F contains a fluorescent marker.

For jetting, the low viscosity version Vitralit® UD 8050 LV is the perfect solution. Thanks to its easy dispensing and fast curing Vitralit® UD 8050 LV is very conven-ient for applications in the production of consumer electronics where a high throughput is needed.

By default, the adhesive is transparent, but it is also available in blue or fluorescing versions. Other colors are available on request.
