High Temperature Coatings — Epo-Weld™
Silicone-glass-ceramic and glass-enamel coatings that fuse into a permanent inorganic protective layer — replacing organic paints that carbonize and fail. Three grades covering light gray and gloss-black finishes for service temperatures from 900°F to 1,400°F on metals and ceramics.
Technical Specifications
Where Epo-Weld™ HTGC Performs
From furnace spacers to rocket nozzle liners — wherever a permanent
inorganic coating must survive extreme heat, oxidation, and chemical attack.
Frequently Asked Questions
Common questions about Epo-Weld™ HTGC high temperature coatings.
-
Incure Epo-Weld™ HTGC coatings protect metals, stainless steel, and ceramics from oxidation, corrosion, and surface degradation in high-temperature industrial environments. They replace organic paints that carbonize at elevated temperatures. Applications include furnace components, exhaust manifolds, electrical insulators, heater coil mandrels, plasma reactor parts, and consumer appliances requiring a durable, thermally stable surface coating.
-
Epo-Weld™ HTGC-271 is a light gray silicone-glass-ceramic coating stable to 900°F, suited for furnace spacers, insulators, and heater coil mandrels. HTGC-272 is a black silicone-glass-ceramic coating rated to 1,400°F for extreme environments including rocket nozzle liners, plasma reactor parts, and metallurgical crucibles. HTGC-273 is a gloss-black glass-enamel coating stable to 1,000°F designed specifically for stainless steel consumer appliances, oven panels, and decorative metal parts where a high-gloss vitreous finish is required.
-
Apply Epo-Weld™ HTGC coatings by brush or spray to a clean, dry substrate. HTGC-271 cures in two stages: 1 hour at 200°F followed by 1 hour at 300°F. HTGC-272 and HTGC-273 cure in 2 hours at 200°F. Final high-temperature properties develop during the first thermal excursion to service temperature as the glass frits fuse into a continuous inorganic matrix.
-
Epo-Weld™ HTGC coatings adhere to steel, stainless steel, cast iron, alumina ceramics, and other oxide surfaces. HTGC-273 is specifically formulated for stainless steel substrates. All grades require clean, dry surfaces for best adhesion.
-
Yes. After full cure, Epo-Weld™ HTGC coatings resist moisture, mild acids, alkalis, salt spray, and chemical fumes. The inorganic glass-ceramic matrix is chemically inert and does not absorb solvents or moisture, making HTGC grades suitable for process vessels and heat exchangers in corrosive industrial atmospheres.
-
Epo-Weld™ HTGC-272 is rated to 1,400°F (760°C) continuous service temperature — the highest in the HTGC range. It is designed for extreme thermal environments including rocket nozzle liners, plasma reactor components, and metallurgical crucibles where standard high-temperature coatings fail.
