Understanding Epoxy Mixing Ratios
Selecting the wrong epoxy system can lead to overheating (exotherm runaway) or rubbery, uncured results. Here is the definitive guide to choosing between IRIKA 2:1 and 3:1 systems.
| Feature | IRIKA 2:1 Universal Art Resin | IRIKA 3:1 Deep Pour Casting Resin |
|---|---|---|
| Max Single Pour Depth | 10 mm (Coasters, Trays, Canvases) | 50 mm / 2 Inches (River Tables, Blocks) |
| Pot Life (Working Window) | 45 Minutes | 180 Minutes (Slow Exotherm) |
| Demold Time | 12 – 16 Hours | 36 – 48 Hours |
| Cured Hardness | 90+ Shore D | 85+ Shore D |
When to Pick 2:1 Art Resin
Ideal for 90% of daily studio projects: clear protective top coats, silicone coaster molds, flower preservation in thin layers, jewelry bezels, and textured geode wall art.
When to Pick 3:1 Deep Pour Resin
Essential when pouring large volumes (above 1 kg) with significant depth, such as live-edge wooden river dining tables or deep memorial pyramid blocks.
