RTV 800 Series UV/Dual (UV/moisture) cure materials, for encapsulating and staking sensitive components, have reported cure speeds of fewer than three seconds. Patented chemistry permits paste-like products to cure up to 5/8" thick with minimal energy requirements. Viscosity of encapsulant ranges from a few hundred centipoises (for spraying and dip coating) to several thousand for thick coating and deeper potting applications up to 3/8" thick. Are self-leveling and flowable, and shadow cure at room temperature. Are based on silicone chemistry, translucent, and do not degrade or yellow on long-term exposure to light.
