DYMAX: UV/Visible Light-Curing Silicone (9/29/09)

September 29, 2009


DYMAX Cure-PointTM 9440-A/B cures to depth in seconds upon exposure to UV/visible light to provide protection to electronic components and circuitry. It is a UV/visible light-curable silicone potting and sealing material designed for applications where fast cure, enhanced thermal performance, and room-temperature shadowed-area cure are required. Cure-Point 9440-A/B has a >90 day room temperature mix life.

This product is designed to withstand long exposure to temperatures ranging from below -40°C to above 200°C while retaining fast-cure processing benefits associated with UV-curable materials. This makes it superior to RTV silicones and heat-cure silicones which require longer cure times or elevated temperatures to cure. Cure-Point 9440-A/B excels in applications where oil or chemical exposure are present. It also features a fast, tack-free cure with negligible shrinkage.

DYMAX UV/visible light-curable materials are solvent free and their ability to cure in seconds results in lower processing costs. When cured with DYMAX light-curing spot lamps, focused beam lamps or flood lamps, they deliver optimum speed and performance for maximum efficiency. This product is in full compliance with the RoHS Directives 2002/95/EC and 2003/11EC.
