UV-3010 UV Curable Conformal Coating / Encapsulant

UV-3010 UV Curable Conformal Coating / Encapsulant Description:

Specifically engineered for water resistance on printed circuit board protection and LED component protection in membrane switches.

Surface Resistivity: 3.8 x 1014 ω/■

• 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
• 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
• Meets UL 94V-0 flammability requirements, as well as the specifications of MIL 46058-C for printed circuit boards.
• UV cure is accomplished within seconds, allowing for high speed production.
• Rheology of UV-3010 makes it suitable for syringe dispensing. UV-3010 can also be heated to drop its viscosity for spray or dipping applications.
• High temperature resistance of UV-3010 allows it to be used in wave soldering applications

Applications:

• Component encapsulation
• Printed circuit board protection

Application Guidelines

UV-3010 can be applied by all conventional methods including syringe dispensing, 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.

Curing

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.
