9663


Low Outgassing, Light-Curable Keypad Coating

Ultra Light-Weld® 9663 adhesive cures in seconds upon exposure to UV/Visible light for rapid coating of mobile phone keypads. 9663 features low outgassing and is able to endure vacuum metalizing processes. The low viscosity of this material helps minimize air entrapment. The product cures tack free and is also highly flexible. Recommended substrates include PC, and PET, as well as PETG.

Dymax materials are solvent free and cure upon exposure to light. Their ability to cure in seconds results in lower processing costs. When cured with Dymax UV light curing spot lamps, focused beam lamps, flood lamps, or conveyor systems they deliver optimum speed and performance for maximum efficiency. Dymax lamps offer the optimum balance of UV and visible light for the fastest, deepest cures. Ultra Light-Weld® 9663 is in full compliance with the RoHS2 Directives 2015/863/EU.
