DYMAX Cure-Point™ 9440-A/B is a silicone which 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 pot life of greater than 90 days at room temperature after mixing.
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.
