UV-3010
UV Curable Water Resistant
Conformal Coating/Encapsulant

UV-3010 is a 100% solids, UV cure conformal coating that has been engineered specifically for telecommunications printed circuit board protection and LED and diode protection in membrane switches. The insulation resistance of cured films of UV-3010 at 100°C and 95% relative humidity is one of the highest and most stable of any coating in the marketplace, including epoxy, silicone and urethane. A cured film of UV-3010 will withstand extreme thermal shock and thermal cycling from +150°C to -60°C, while maintaining its electrical integrity over a wide temperature and frequency range. UV-3010 meets UL 94V-0 flammability requirements, as well as the specifications of MIL 46058-C for printed circuit boards. UV-3010 can be mixed with a catalyst to give it a dual cure mechanism, which allows for complete curing at room temperature after exposure to UV light - even underneath components. UV cure is accomplished within seconds, allowing for high speed production. The rheology of UV-3010 makes it compatible with spray or dip operations. The high temperature resistance of UV-3010 allows it to be used in wave soldering applications.

APPLICATION METHODS:

UV-3010 can be applied by all conventional methods including dip, roll or knife over roll coating and curtain coating. The low viscosity allows spraying without the need for thinning with organic solvents. The excellent pot life and UV cure mechanism allow for heating of the material to precisely control viscosity for consistent application weights.

METHOD OF CURE:

UV-3010 must be exposed to ultraviolet light of the proper wavelength to activate the curing mechanism. This can be done with any ultraviolet light source which puts out wavelengths of <380 nanometers. The most common commercial light source is the medium pressure mercury vapor (MPMV lamps), electrode or microwave activated arc, with or without spectral enhancement (doped). Cure can also be accomplished with xenon or carbon arc lamp sources, UV lasers or electron beam sources. These sources are available in increasing arc lengths and varying intensities for specific applications from a large number of manufacturers. In general, greater than 900 mJ/cm2 of UV energy is needed to completely cure this material in thin cross sections.
