Once fully cured, Craft Resin is heat resistant enough for everyday use, but each product line has a different
ceiling. Use this guide to check whether your finished piece is safe for its intended use — hot drinks, sunny
windowsills, or a spot near the stove.
Heat resistance by product (once fully cured)
| Product | Safe up to |
|---|---|
| Arts & Crafts | 80°C / 176°F |
| Deep Pour | 80°C / 176°F |
| Table Top | 90°C / 194°F |
| UV Resin | 60°C / 140°F |
Important: this applies to fully cured resin only
These figures describe resin that has gone through its full cure — not the initial "hard cure" stage where
the surface feels dry but the resin hasn't finished its complete chemical cure. Full cure time varies by
product (see our Mixing Ratio and product-specific guides); using a piece for hot items before it has fully
cured can cause softening, warping, or a hazy finish even though the surface felt hard days earlier.
For Table Top specifically, this heat-resistance rating is conditional on a full 21-day cure — the 90°C/194°F figure applies once a piece has fully cured for a full 21 days, not before. Arts & Crafts and Deep Pour reach their rated 80°C/176°F once fully cured, without a specific day-count condition currently established.
Practical guidance
- Coasters and trivets: fine for warm mugs and plates within the limits above, once fully cured. Avoid
resting anything straight off the stove or a very hot pan directly on cured resin.
- Sunny windowsills or car interiors: surface temperatures in direct summer sun can exceed 60–70°C, which
is within range for Arts & Crafts and Deep Pour but can be enough to soften UV resin pieces over time —
keep UV resin items out of prolonged direct sun and heat.
- Serving trays: suitable for incidental contact with already-plated food at typical room temperature once fully cured — not for direct, prolonged or repeated food contact (see our
Food Contact article for the full picture).
