Dow Corning 99180648 Rtv Silicone Joint Sealant 10.1 Oz

Product Description

The DOW CORNING 99180648 is a Series 832 RTV silicone joint sealant packaged in a 10.1 oz cartridge. It cures at room temperature to form a flexible, durable seal rated for continuous service from -67 degrees F to 300 degrees F (equivalent to -55 degrees C to 149 degrees C). The off-white color blends into common construction and mechanical surfaces. With a tack-free dry time of 90 minutes, crews can move on to adjacent work without extended delays. Licensed tradespeople and facilities maintenance technicians use this sealant in HVAC, plumbing, marine, and general construction applications wherever a resilient silicone bead is required.

This sealant is suited for residential and commercial applications involving floors, gaskets, gutters, insulating assemblies, and marine environments. It bonds to a wide range of substrates including concrete, glass, masonry, metal, plastic, and rubber, making it a versatile option across multiple trades. The cartridge format is compatible with standard 10 oz caulking guns, allowing direct integration into existing tool sets on the job site.

Installation Notes

Application is performed by licensed tradespeople or qualified maintenance personnel using a standard caulking gun. Clean and dry the substrate thoroughly before applying the sealant bead; contaminants such as oil, dust, or moisture will reduce adhesion. Allow the full tack-free cure period of 90 minutes before subjecting the joint to contact or light service. Follow all applicable local building codes and the manufacturer safety data sheet for ventilation and personal protective equipment requirements.
