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.
