Deep Pour River Epoxy (2:1 Ratio) for Custom Geometric Block Calculator
Pre-loads specific gravity (1.11) and 2:1 mix ratio to calculate exact Part A & Part B weights with cup scraping buffer.
A standard Custom Geometric Block (12 × 12 × 8 cm minus 150 cm³ master) requires 1201g (42.37 oz / 2.65 lbs) of Deep Pour River Epoxy (2:1 Ratio). Mix 800.8g Part A with 400.4g Part B (8% buffer included).
Casting Material & Volume Mode
Pre-loads specific gravity and 2:1 ratio by weight.
Geometry determines the container-volume formula. Use water displacement when the cavity is irregular.
Volume displaced by your master object inside the box.
Compensates for resin clinging to mixing paddles and cup walls (8% recommended).
Includes 8% waste buffer at SG 1.11

Step-by-Step Mix Ratio Derivation: Deep Pour River Epoxy (2:1 Ratio)
How displacement volume, specific gravity, and ratio split combine into final scale weights.
Calculates the empty fluid cavity by taking the gross 1152 cm³ box containment volume and deducting the 150 cm³ displaced by the master model.
Multiplies fluid volume by the specific gravity of Deep Pour River Epoxy (2:1 Ratio) (1.11 g/cm³) plus an 8% buffer for cup scraping and pouring loss.
Distributes batch mass according to the exact 2:1 ratio by weight.
Engineering Specifications & Troubleshooting Guide: Deep Pour River Epoxy (2:1 Ratio)
Factory-tested parameters, common failure modes, and workbench best practices.
- Specially formulated with ultra-low viscosity and slow exothermic release for single pours up to 2 inches (50mm) deep.
- Keep workshop temperature strictly between 20°C - 22°C (68°F - 72°F); hotter ambient will cause an exothermic runaway boil.
- Pass a propane torch or heat gun lightly over the surface 15 minutes after pouring to pop rising bubbles.
Pouring deeper than recommended in hot weather (>26°C), resulting in thermal yellowing, cracking, and smoke.
