Lab-tested heat performance
Clear Epoxy Built for Elevated-Heat Projects
POURLA Ultra Heat Resistant Epoxy Resin combines a simple 1:1 mix by volume, a clear high-gloss finish and a laboratory-tested 195°F / 90°C Heat Distortion Temperature for functional resin work.
Heat-resistant does not mean heat-proof. Use a trivet or insulated pad under cookware and other very hot objects.
Performance you can evaluate
More Than a “Heat-Resistant” Label
Clear specifications make it easier to choose the right resin, follow the correct process and set realistic expectations for the finished project.
Heat Distortion Temperature
A laboratory-tested reference for when a fully cured material begins to soften or deform under a specified load.
High-Gloss Appearance
Enhances wood, pigments, carbon fiber and embedded materials with greater visual depth and a polished finish.
Shore D Hardness
Cures into a hard surface suited to functional and decorative projects when accurately measured, thoroughly mixed and fully cured.
Water Absorption
Helps finished surfaces resist moisture during normal use, while accurate application and full curing remain essential.
Heat Distortion Temperature is a controlled laboratory measurement. It is more informative than a vague “heat resistant” claim, but it is not the same as a direct-contact or continuous-use temperature rating.
What the number means
Is Epoxy Resin Heat Resistant?
Yes—but performance depends on the formulation, accurate mixing, application conditions and complete curing. POURLA Ultra Heat Resistant Epoxy has a tested HDT of 195°F / 90°C, helping fully cured projects maintain their form during normal elevated-heat exposure.
Recommended applications
Made for Functional Resin Projects
Use it where clarity, hardness and improved resistance to heat-related deformation are important.
Before a full project: Test surface adhesion, pigment compatibility and appearance on a small sample. Seal porous materials when necessary to reduce trapped air and uneven absorption.
Simple measuring, practical timing
Mix Accurately. Work Deliberately.
All timing is approximate at 75°F. Temperature, batch size, humidity, application thickness and mixing accuracy can change the actual working and cure window.
Equal liquid-volume parts of Part A resin and Part B hardener.
Use a scale and measure 1.2 parts resin to 1 part hardener by weight.
Approximate application window at 75°F. Larger batches may warm and react faster.
Protect from dust, moisture and contact while curing. Wait for full cure before heat exposure.
Application guide
How to Use POURLA Ultra Heat Epoxy
Good results begin before the pour. Clean preparation, precise measuring and complete mixing are essential to cure quality.
Prepare the Surface
Make sure the project is clean, dry and free from dust, oil, wax and loose material. Seal porous surfaces when necessary to reduce trapped air and uneven absorption.
Measure Accurately
Combine equal liquid-volume parts of resin and hardener. When measuring by weight, use 1.2 parts Part A resin to 1 part Part B hardener.
Mix Slowly for 5–7 Minutes
Scrape the sides, bottom and corners of the container repeatedly until the mixture is completely uniform. Avoid whipping excess air into the epoxy.
Apply Within the Working Time
Pour or spread the mixed epoxy within the approximate 25–30 minute working window at 75°F. Mix only the amount you can apply during this period.
Protect and Allow a Full Cure
Keep the project away from dust, moisture and contact while curing. Wait approximately 36–48 hours at 75°F before normal use or heat exposure.

Clear expectations build better projects
Designed for Everyday Functional Heat—Not Extreme Heat
The tested HDT is a meaningful performance reference, but no epoxy should be treated as completely heat-proof.
Appropriate Uses
- Heat-resistant epoxy coasters after full cure
- Serving and decorative trays
- Compatible tabletop protective coatings
- Wood, resin and carbon fiber projects
- Functional DIY parts within the tested performance range
Not Designed For
- Cookware placed directly from a stove or oven
- Open flames or direct burner contact
- Oven interiors, engines or exhaust systems
- Furnace service or extreme industrial temperatures
- Continuous exposure beyond the product’s tested limits
Frequently asked questions
Before You Mix
Review the performance limits, ratios and cure requirements before starting your project.
What is heat distortion temperature?
Heat Distortion Temperature, or HDT, indicates when a cured material begins to soften or deform under a specified load. It provides a more useful performance reference than simply describing an epoxy as “heat resistant.”
What is the HDT of POURLA Ultra Heat Epoxy?
The fully cured resin has a laboratory-tested Heat Distortion Temperature of 195°F / 90°C.
Is this epoxy heat-proof?
No epoxy is completely heat-proof. POURLA is heat-resistant within its tested performance range, but protective pads should still be used under very hot objects.
Can I use it for coasters?
Yes. Its clear finish, low water absorption and 195°F HDT make it suitable for heat-resistant epoxy coasters. Allow the project to cure fully before use.
Can I place a hot pan directly on the cured epoxy?
No. Cookware taken directly from a stove or oven may exceed the resin’s performance limits. Always use a trivet or insulated protective pad.
How long should I mix the epoxy?
Mix slowly and thoroughly for approximately 5–7 minutes, repeatedly scraping the sides, bottom and corners of the container until the mixture is uniform.
How long does it take to cure?
Initial set occurs in approximately 5–6 hours. Full cure generally takes 36–48 hours at 75°F. Cooler conditions or other application variables can extend the cure time.
Can pigments be added?
Compatible resin pigments may be used, but pigments can affect curing and final performance. Test a small batch before completing the full project.
Is high-temperature epoxy the same as an industrial furnace adhesive?
No. This product has a tested HDT of 195°F and is not intended for engines, ovens, open flames, exhaust systems or extreme industrial temperatures.

Verified owner Old newbies (verified owner) –
First Pourla pour today, turned out great! We are beginners and it was a small project (4 coasters) we added a mica powder for our first time also, and the coasters look so nice! We do have one that has a dust particle in it 🥴 and was beyond our working window but still a great first project pour with the Ultra Heat.
