Dow Corning 99180483 Rtv Silicone Sealant 10.1 Oz Clear

Product Description

The DOW CORNING 99180483 is a clear RTV silicone joint sealant supplied in a 10.1 oz cartridge, part of the 737 Series. It cures at room temperature to form a flexible, durable seal rated for continuous service from -85 degrees F to 350 degrees F. Tack-free time is 14 minutes, with full cure reached in 24 hours. The cartridge format is compatible with standard caulk guns used in HVAC, plumbing, refrigeration, and food-service equipment applications. Installers working on joints that require a clear, flexible seal across a wide temperature range will find this formulation suited to demanding service environments.

This sealant is designed for use in both residential and commercial applications where a transparent, food-safe silicone seal is required. It bonds to glass, metal, painted surfaces, plastic, and rubber, making it appropriate for sealing joints, seams, and penetrations on HVAC cabinets, ductwork access panels, refrigeration equipment, plumbing fixtures, and food-processing or food-service equipment. The 737 Series formulation is noted as food safe, broadening its application to environments with sanitation requirements. It is not paintable, so it should be applied only where a clear finish is acceptable.
