Which Epoxy Resins Offer Heat Resistance Up to 70°C [158°F]?

For many professional or creative applications, selecting an epoxy resin with reliable heat resistance is critical. See which options maintain their properties up to 70°C [158°F], and how to choose the right product for your next project.

Understanding Heat Resistance in Epoxy Resins

Heat resistance in epoxy resins refers to their ability to retain strength, clarity, and integrity when exposed to high temperatures. Many standard resins soften or yellow when subjected to heat, but specialised formulations like Epoxytable 10-Ten and EpoxyTable 5-Five are engineered to withstand temperatures up to 70°C. This makes them ideal for projects exposed to occasional warmth, such as sunlit surfaces or locations near gentle heat sources.

Selecting the Right Resin for Your Needs

When choosing a heat-resistant epoxy, consider both casting thickness and the intended application. For deep pours and large castings, Epoxytable 10-Ten supports thicknesses up to 10cm without overheating, while EpoxyTable 5-Five suits medium-depth projects up to 5cm. If your needs centre on surface coatings or thinner layers, Art Pro offers a clear, scratch-resistant finish with heat resistance up to 70°C, perfect for artwork and decorative surfaces.

For large or deep casts: choose a resin formulated for thick layers to minimise bubbling and avoid overheating.
For thin or decorative coatings: opt for products designed with non-drip, easy-mix formulas suitable for surface protection.

When Heat Resistance Matters Most

Epoxy’s temperature resilience is especially important for tables in sun-exposed rooms, artistic castings displayed under spotlights, and any applications exposed to warm conditions. While these resins offer stable performance up to 70°C, extended exposure to higher temperatures should be avoided to preserve finish and clarity.
