Packaged in a 10.1 fl oz cartridge, this non-slump, paste-consistency formula cures at room temperature by reacting with ambient moisture to form a durable, flexible silicone rubber. The white color suits visible joint work where aesthetics matter. With a rated service range of -62 degrees F to 400 degrees F, it holds up in both high-heat exhaust applications and cold-climate installs.\u003c\/p\u003e\u003cp\u003eThis sealant is suited for a broad range of industrial and mechanical sealing tasks, including duct joints, equipment housings, gasket fabrication, and general-purpose adhesive bonding in HVAC and related trades. The one-component RTV format requires no mixing, making it practical for field use by HVAC technicians, plumbers, and mechanical contractors working on residential and light commercial systems. The paste-like, non-slump consistency allows controlled application on vertical and overhead surfaces without sagging before cure.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e100% silicone, one-component RTV formula cures by moisture reaction at room temperature\u003c\/li\u003e\n\u003cli\u003eNon-slump, paste-like consistency for controlled bead placement on vertical and overhead surfaces\u003c\/li\u003e\n\u003cli\u003eService temperature range of -62 degrees F to 400 degrees F suits high-heat and cold-climate applications\u003c\/li\u003e\n\u003cli\u003eWhite color finish for use on visible joints and trim-out work\u003c\/li\u003e\n\u003cli\u003e10.1 fl oz cartridge compatible with standard caulk guns\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose one-component RTV silicone sealant for industrial sealing and adhesive applications across HVAC, mechanical, plumbing, and related trade uses.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eApplication is typically performed by HVAC technicians, pipefitters, or mechanical contractors using a standard cartridge caulk gun. Surfaces should be clean, dry, and free of grease or loose material before applying sealant. Allow adequate cure time before exposing the joint to service conditions; cure rate depends on ambient temperature and humidity.
