A conformal coating is used to protect electronic components from environmental factors. Adhesives used as conformal coatings are dual-curing: at their edges and visible surfaces they are cured with UV light; the shaded zones – for example underneath components or chips – as well as deeper-lying regions are then cured by heat application.
To cover large surfaces with a conformal coating, we recommend low-viscosity adhesives. These adhesives are equally suited for spray coating, spin coating and dip coating.
Selective conformal coating can be realized with high-viscosity dam material: With a highly viscous adhesive, a frame or dam is formed, which is then filled with mobile adhesive. This process is also referred to as dam-and-fill.
UV-curing conformal coatings allow rapid curing. Especially epoxy resin-based adhesives are silicone-free and ensure maximum media resistance.
The table below lists a selection of Panacol adhesives suitable as conformal coating. Further products and custom solutions are available on request.
