800-235 is a UV curable semi-flowable silicone pottant or sealant.

This non-corrosive, single component silicone will cure to a solid elastomer in seconds upon exposure to ultraviolet (UV) light. A UV-cure only silicone with limited adhesion, 800-235’s higher viscosity makes it ideal for cured-in-place gaskets.

With a viscosity of 79,000 cPs, 800-235 enhances reliability of delicate components, and provides both stress and shock relief.
