Frequently Asked Questions
Common questions about Epo-Weld™ UHTC ultra high temperature coatings.
-
Epo-Weld™ UHTC is an aluminum-filled coating for high-temperature lighting applications — automotive headlamps, mercury vapor lamps, and HID arc lamps. It delivers reflective, heat-resistant surface finishes stable up to 1200°F.
-
Service temperature depends on the formulation. Epo-Weld™ UHTC-466 and UHTC-475 are rated to 1020°F; Epo-Weld™ UHTC-484 (white formulation) is rated to 1200°F for mercury vapor and arc lamp applications.
-
No — Epo-Weld™ UHTC is a single-component coating requiring no mixing. It cures at room temperature, simplifying application and enabling faster throughput on lamp assembly lines.
-
Epo-Weld™ UHTC cures at room temperature for 1 hour, with an optional 30-minute post-cure at 400°F. The post-cure improves thermal stability for demanding high-temperature service.
-
Epo-Weld™ UHTC-484 is the white formulation designed for mercury vapor lamps, arc lamps, and stadium lighting. It provides a highly reflective white surface stable to 1200°F and resists yellowing under intense UV and thermal radiation.
-
Epo-Weld™ UHTC coatings are aluminum-filled. UHTC-466 and UHTC-475 are silver grades; UHTC-484 is a white aluminum-filled formulation. The aluminum filler provides the reflective, heat-resistant properties required for lighting applications.
