Why Choose Clear Rigid Epoxy Casting Resin?
Perfect for Deep Casting, River Tables & Bartops
This resin is designed for thick pours with a long pot life (8–10 hours) and low exotherm, ensuring the mixture does not overheat during deep casting. Ideal for:
-
River tables
-
Bartops and countertops
-
Decorative castings
-
Resin wood furniture
-
Large, clear moulds
-
High end art and interior décor
Beautifully Clear with Excellent UV Resistance
The resin cures to a totally clear, glass like finish, and its UV resistant formula helps delay yellowing. All epoxies eventually yellow, but with proper care and limited sun exposure, this resin stays clear for a very long time.
Excellent Optical Properties & Negligible Shrinkage
You get high-quality, dimensionally stable castings with almost no shrinkage. Ideal for precise mould work and professional furniture finishes.
Highly Accurate Mixing Ratio – Consistent Results Every Time
Mixing by volume: 2 parts resin to 1 part hardener
Mixing by weight: 100g resin to 45g hardener
A completely homogeneous mix is essential. Best practice includes:
-
Pouring the hardener first
-
Scraping sides and bottom during mixing
-
Re-mixing in a second container
-
Mixing only what you need to avoid overheating in large masses
How to Use – Professional Guide
Preparation
-
Room and material temperature: 18–25°C
-
Humidity: below 70%
-
Ensure moulds are clean and ready
-
Suitable for gravity casting, vacuum, or pressure casting
Application
After mixing, pour the resin into silicone or hard moulds.
The mixture flows well, releases air easily, and remains cool when used correctly.
Pot life at 22°C for 500g mix: 8–10 hours.
Suitable for intricate shapes and decorative parts.
If applying a new layer onto cured resin, always sand the surface to improve adhesion.
Curing Time
Curing depends on volume and thickness.
| Casting Size | Temperature | De-mould Time |
|---|---|---|
| 500g, 10 cm thick | 25°C | ~36 hours |
| Thin sections | 20–25°C | Varies; can be accelerated by post-curing |
Post-cure option for faster results:
-
Let cure at room temperature for 24 hours
-
Then heat gradually to max 60°C for 15 hours
Final mechanical strength is reached after:
-
21 days at 20°C, OR
-
15 hours at 60°C

Troubleshooting Guide
| Problem | Cause | Solution |
|---|---|---|
| Resin is cloudy or crystalline | Cold temperature or long storage | Warm to ~50°C until clear, agitating frequently |
| Not curing after 24–48 hrs | Incorrect mixing ratio or low temperature | Remix accurately, ensure 18–25°C |
| Mixture becomes too hot | Too much resin mixed at once / high temperature | Mix smaller batches, reduce ambient temperature |
| Entrapped air bubbles | Mixed too fast | Mix slowly and allow air to escape |
| Sticky or greasy surface | Humidity too high | Keep humidity below 70% |
Packing & Storage
