Clear RTV Silicone

RTV615 is a two-component fast cure clear RTV silicone which cures at room temperature to form a high-strength silicone rubber when the curing agent is added. This quick cure silicone is supplied with curing agent in matched kits designed for use with a convenient 10:1 ratio by weight.

A fast-cure RTV silicone, RTV615 is a colorless and pourable liquid with a nominal viscosity of around 4000 cps.

As an optically clear silicone encapsulant, RTV615 is used to protect electronic components and assemblies against shock, vibration, moisture, ozone, dust, chemicals, and other environmental hazards, by potting or encapsulating said components and assemblies.

The optical clarity of this silicone rubber compound allows for visual evaluation in various applications, such as potting solar cells for maximum light transmission, or potting electronic assemblies where component identification is necessary or desirable. It also makes RTV615 a great silicone casting resin.

Our other clear RTV silicone is RTV12. For high temperature RTVs, use RTV60 or RTV88. Our blue and white silicones – RTV630 and RTV11 – are ideal choices for mold making.

We also offer epoxy and urethane potting compounds.
