Thurmalox® 260 is specifically designed for industrial environments where metal surfaces are exposed to high heat and harsh conditions. It’s commonly used on furnaces, heat exchangers, boilers, turbines, compressors, flare stacks, and refinery equipment. Its durable silicone copolymer base provides long-lasting protection against oxidation, corrosion, and chemical exposure in continuous temperatures up to 500°F (260°C).
This coating’s resistance to corrosion comes from its advanced silicone copolymer resin combined with an effective corrosion-inhibitive pigment system. Together, they create a dense, chemically stable film that blocks moisture, oxygen, and chemicals from reaching the substrate. Even under sustained heat, the coating maintains its integrity, preventing blistering, peeling, and metal degradation.
Before applying Thurmalox® 260 to stainless steel, all contaminants such as oils, grease, and residues must be removed through solvent or steam cleaning. Chlorinated solvents should never be used. For smaller areas, wiping with Dampney 170 Thinner is recommended. Proper cleaning ensures excellent adhesion and performance, even without abrasive blasting.
At 70°F (21°C) and 50% relative humidity, Thurmalox® 260 dries to the touch in 4–6 hours and can be recoated after 8–10 hours. While its air dries naturally, optimum film strength and durability are achieved after a heat cure at 350°F (177°C) for 30 minutes, typically occurring during equipment operation.
