Can You Put Hot Items on Epoxy Resin?
Can You Put Hot Items on Epoxy Resin?
When working with epoxy resin, many people wonder if it’s safe to place hot items like a mug or plate directly onto the surface. The truth is, epoxy resin has excellent heat resistance, but there are limitations. The material’s durability and gloss can be compromised if exposed to high temperatures for too long. Typically, most resin surfaces can withstand temperatures up to around 120°F (50°C), which is fine for placing a mug or plate with a warm drink.
However, anything higher—such as a hot dish fresh from the oven—can cause irreparable damage, like heat marks or cloudiness, ruining your beautiful creations. To avoid these risks, it’s best to use coasters or trays for protection. Even though ArtResin and similar quality formulations offer strong resistance against heat, the surface needs to be fully cured before placing anything hot on it.
If not, the resin may soften, leading to indentations or other damage. So, while resined surfaces look stunning for art and decorations, always protect them when dealing with high temperatures to keep your countertops and surfaces looking flawless.
Temperature Threshold
When using epoxy resin, it’s important to check the manufacturer’s specifications to understand the maximum temperature it can withstand. Most classic resins handle up to 70°C, so a warm mug or plate placed on a resin coaster is usually fine. However, hot objects beyond this can leave a noticeable melted mark, especially if the temperature of dishes is too high when serving.
Direct Contact
Avoid placing hot items like hot pots, pans, or plates directly on your epoxy resin surface. The intense heat can cause heat marks, cloudiness, and even indentations as the resin softens, which can end up damaging the finish. Always use a protective layer to keep your resin looking pristine.
Use Protection
I once placed a steaming cup of coffee on my epoxy resin surface, thinking it could handle the heat. A few minutes later, I noticed a faint mark. This is why using protective items like trivets and placemats is important. If you set hot dishes directly on the surface, it can damage the glossy finish.
