Do you have an epoxy with higher heat resistance than 135°F?

No, and no consumer-grade tabletop epoxy truly does. All clear tabletop epoxy systems have a similar heat deflection temperature (HDT) in the range of 120°F to 135°F; the UltraClear Epoxy system is 135°F. Above that range, any consumer-grade epoxy can begin to soften, lose gloss, or distort under heat and pressure, which is why trivets or heat pads are always needed for pans and dishes coming from the stove or oven.

You may see other brands advertise heat resistance of 450°F to 500°F. That figure typically refers to the temperature at which the epoxy begins to thermally degrade or scorch, not the temperature it can safely handle in regular use. In real-world terms, the heat tolerance of tabletop epoxies is very similar across brands.

If you need technical data, the SDS for our epoxy products is available at https://ultraclear.helpscoutdocs.com/article/18-epoxy-msds

Our epoxy is designed for top-coating surfaces such as tables, bar tops, and countertops. It is not designed for high-temperature industrial uses, such as coating machinery or parts that operate at high temperatures. For unusual situations involving occasional contact with very hot objects, such as a glass-bending bench, we have no prior experience to draw on and you would need to test it for your specific needs.
