Imperial KK0202 Black Silicone Sealant 10.3 Oz High Temp

Product Description

The IMPERIAL MFG GROUP USA INC KK0202 is a black silicone sealant formulated for high-temperature applications in HVAC, plumbing, and general mechanical service work. Packaged in a standard 10.3 oz cartridge, it resists temperatures up to 450 degrees F (232 degrees C), making it suitable for use near heat-generating equipment, flue components, and metal assemblies. The sealant dries to the touch in 30 minutes and reaches a full cure in 24 hours. Licensed technicians and service pros reach for this type of product when a flexible, heat-resistant seal is needed on a wide range of substrates.

The KK0202 is suited for residential and light commercial applications where a durable, flexible bond is required. It adheres to clean metal, glass, most types of wood, ceramic, plastic, brick, and slate. Common install scenarios include sealing around furnace components, ductwork penetrations, venting assemblies, and mechanical enclosures where temperature cycling would degrade standard sealants. It is sold in cases of 12 cartridges, making it practical for service trucks and shop stock.
