Silicone cures to depth in seconds

Written by: Chris Shaw | Published:

Intertronics has launched Dymax Cure-Point 9440-A/B silicone, which it says cures to depth in seconds upon exposure to UV/visible light, providing 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.

The 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. According to Intertronics, this makes it superior to RTV silicones and heat-cure silicones which require longer cure times or elevated temperatures to cure. It is suitable in applications where oil or chemical exposure are present and features a tack-free cure with negligible shrinkage.

Dymax UV/visible light-curable materials are solvent free.
