Resin Calc: Epoxy Mix Ratio

Know exactly how much epoxy resin and hardener to mix, and measure it with what you have. Most calculators ignore that resin and hardener have different densities, so a ratio by volume is NOT the same by weight. Resin Calc gets it right and shows both: grams for your scale, ml for your cups. • Rectangle, cylinder or custom volume, multiple pieces, waste % • Any ratio (1:1, 2:1, 3:1…) by volume or by weight • Part A and Part B in grams and ml • Editable densities, with a warning when they are estimated • Cost of the pour from your kit price • Metric and imperial units, works offline Always follow your product's technical data sheet.
