Primary Characteristics

Self leveling

Addition cure

Cures in deep sections

Very high strength

Medium viscosity

Primer required

Use for:

Encapsulating applications requiring high tensile strength

Exceptionally deep potting applications

Will form thin, light-weight molds with excellent durability. The high tear resistance and inherent release ability make it well suited to the manufacture of intricate castings, by reproducing each part exactly to detail. Other applications include prototype parts, production tools for casting epoxies and rubber rolls. Electrical circuits require a tough potting compound with outstanding vibration withstanding capability find RTV630 unequalled. Silicone primeris required.
