In environments subjected to extreme heat, standard sealants often fail, compromising the integrity of crucial components. Asmaco Hi-Temp 100% RTV Silicone Sealant, supplied by A1A Wholesale Supply, is specifically formulated to perform reliably in these challenging conditions, offering a durable and elastic seal that can withstand temperatures up to 572°F.
This one-part, non-sagging sealant cures at room temperature into a resilient, seal-like solid. Its fast-curing properties ensure efficient project completion, while its permanent flexibility guarantees long-term performance without cracking or breaking under thermal stress. The non-sag paste consistency makes it easy to apply and tool with a spatula or applicator, ensuring a professional finish.
Beyond its high-temperature capabilities, Asmaco Hi-Temp 100% RTV Silicone also boasts 100% weatherproof protection, UV resistance, and 7-year mold and mildew protection, making it versatile for both internal high-heat applications and external exposures. It’s ideal for creating gaskets, sealing and encapsulating elements in appliances, sealing stove and furnace vent pipes, use in moving oven belts and industrial ovens, on bag filters on smoke stacks, and for other high-temperature bonding, sealing, encapsulation, and potting applications. It also serves as a reliable construction sealant for caulking joints in equipment and sheet metal stacking in the insulation industry. This non-paintable sealant meets stringent industry standards including ASTM C-920, Class 25, assuring adherence to recognized quality and performance criteria.
