The Momentive RTV615 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. All are low viscosity, easily pourable liquids with nominal viscosities ranging between 3000 and 7000 cps.

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. RTV655 and RTV656 silicone rubber compound are preferred where flexibility at temperatures down to -115°C (-175°F) is required.
