RTV Silicone 2-Part Potting Encapsulating Compound

1 Pint

A white, two component, low viscosity potting compound that cures at room temperature to a soft pliable rubber. Will cure in deep sections. Designed to acheive primerless adhesion to many substrates, including metals, plastics, and ceramics. The excellent electrical properties make it a candidate material for both high and low voltage electrical assemblies. Cushions against mechanical shock and vibration.
