Ultra High Temperature Epoxy Adhesives — Epo-Weld™
Specialized formulations rated to 572°F (300°C) — chemically resistant, thermally conductive, electrically insulating, and flexible grades for space electronics, aerospace structures, and demanding industrial applications. All formulations meet NASA outgassing requirements where standard adhesives degrade.
Technical Specifications
Built for Extreme Heat Bonding Applications
Epo-Weld™ UHTE adhesives are specified wherever standard epoxies degrade, outgas, or lose bond strength —
rated to 572°F with NASA outgassing compliance for the most demanding environments.
Frequently Asked Questions
Common questions about Incure Epo-Weld™ UHTE ultra high temperature epoxy adhesives.
-
Epo-Weld™ UHTE grades are rated to 572°F (300°C) — the highest service temperature in the Epo-Weld™ epoxy range. This makes UHTE suitable for applications near furnaces, exhaust systems, power electronics under sustained high thermal load, and aerospace components exposed to extreme heat.
-
Standard high-temperature epoxies are rated to approximately 200–250°F. UHTE is formulated for applications that exceed this range, with high cross-link density that prevents softening, chemical penetration, and delamination at temperatures that standard epoxies cannot withstand.
-
Yes. Epo-Weld™ UHTE-5321 is a single-part flexible contact adhesive engineered for bonding materials with dissimilar coefficients of thermal expansion. Its high peel strength accommodates thermal movement without cracking or delamination — important for ceramic-to-metal, glass-to-metal, and composite-to-metal assemblies.
-
Yes. Epo-Weld™ UHTE grades meet NASA outgassing requirements (ASTM E595), confirming suitability for aerospace, satellite, and vacuum applications operating at extreme temperatures.
-
Epo-Weld™ UHTE-5320 provides superior resistance to acids, alkalis, steam, solvents, and salt spray in addition to thermal resistance up to 300°C. The high cross-link density prevents chemical penetration in aggressive industrial and outdoor environments.
-
Epo-Weld™ UHTE bonds metals (steel, aluminium, copper), ceramics, glass, and engineering composites — particularly effective in dissimilar-material assemblies that must survive both extreme heat and aggressive chemical environments.
