UV Mask Material

UV mask material is typically used in high value component fabrication that involves processes for surface enhancement, including acid cleaning or grit blasting. Some surfaces or internal cavities may need to be insulated from these processes. Masking materials are applied to act as temporary barriers, that are subsequently removed from the completed component after processing. Applications include manufacturing of turbine components, orthopedic devices or prosthesis, or other industrial processes involving metal or nickel components.

The UV masking material is derived from light curable adhesive technology. Panacol’s family of UV light curable mask materials are solvent-free and can be easily applied and cured in seconds with a UV light source. The uncured liquid mask can be applied on components by syringe, brush, dip, or spray. All Vitralit® MASK materials provide consistent protection from high impact particulates, hot acids, alkali solutions, plating, and paint. The masks are available in many viscosities to accommodate a wide variety of component configurations and applications. Both high and low viscosity spray masks from Panacol can be easily dispensed and sprayed onto larger surfaces. Some maskants are of green color to provide better visual inspection.

Removal of Panacol mask materials with lower adhesion is accomplished by a simple peel, or a hot water dip and peel. Some maskants with very high adhesion are best removed through incineration. The materials leave no surface residue after peeling or incineration.
