Momentive Two-Part High Strength Silicone Rubber Compound Kit, 500V/mil Dielectric Strength, Clear, 1 lb. kit, Bottles RTV615-1P

MOMENTIVE silicone rubber compounds are Clear liquids which cure at room temperature to high strength silicone rubber with the addition of curing agents. These two-component products are supplied with curing agent in matched kits which are designed for use at a convenient 10:1 ratio by weight. These compounds are Clear and colorless but differ in low temperature flexibility. They are low viscosity, easily pourable liquids with nominal viscosities ranging between 3000 and 7000 CPS. It has been used for protection of electronic components and assemblies against shock, vibration, moisture, ozone, dust, chemicals, and other environmental hazards by potting or encapsulation of the components and assemblies. The optical clarity of these silicone rubber compounds suggests evaluation for applications such as potting solar cells for maximum light transmission and electronic assemblies where component identification is necessary or desirable. Silicone rubber compound are preferred where flexibility at temperatures down to -115 Degrees C is required. Cure rate can be Accelerated by heat. Will cure in deep sections or enclosed assemblies without exotherm and with low shrinkage. Chemical composition contains no solvents for ease of use on production lines. Reversion resistance and hydrolytic stability permit use in high humidity environments at elevated temperatures. Clarity permits visual inspection for easy identification and repair of encapsulated parts. Retention of elastomeric properties at temperatures up to 204 Degrees C. Silicone rubber compounds will cure sufficiently in 24 hours at 25 Degrees C to permit handling. To achieve optimum properties an elevated temperature cure or a cure time of 7 days at room temperature is required. These silicone rubber compounds require a primer to bond to non-silicone surfaces. Silicone rubber compound may be used in food contact applications where FDA regulations apply. 500 V/mil dielectric strength.
