(March 19, 2008) CLEVELAND — Novagard Solutions released RTV 800 Series UV/dual cure and UV gels for use in potting, encapsulating, and conformal coating of delicate components, PCBs, lighting assemblies, and various wiring/current-carrying electrical devices. Cure speeds can be less than 3 sec.
The proprietary chemistry reportedly allows paste-like products to cure up to 5/8" thick with minimal energy requirements for shortened production times. Physical properties can be varied including the viscosity of encapsulant types from a few hundred centipoises for spraying and dip coating to several thousand for thick coating and potting applications up to 3/8" thick. Self-leveling, the flowable materials shadow cure at room temperature.
RTV 800 Series UV gels are available in two hardnesses with good electrical properties. Cure takes place in less than 3 sec., and potting can be performed up to 0.25" thickness. The UV/dual cure series technology is based on silicone chemistry, exhibiting the physical properties of thermal stability, moisture and weather resistance, and resistance to color change. The translucent materials are designed to prohibit yellowing or degradation with long-term light exposure. UV/dual cure products continue to build strength after the initial UV cure cycle.
The materials can be stored at ambient temperature are do not contain solvents.
