About EpoxyResin-Calculator
We built EpoxyResin-Calculator.com to eliminate the guesswork, wasted chemical batches, and dangerous thermal runaway in resin woodworking, art casting, and composite fabrication.
01Why We Created This Tool
Epoxy resin is one of the most versatile and stunning materials in modern craftsmanship—used in live-edge river tables, deep casting molds, high-gloss bar tops, carbon fiber lamination, and jewelry art. Yet, it is also notoriously unforgiving.
Under-measuring volume means scrambling to mix another batch mid-cure, resulting in visible seam lines, bubbles, and compromised bond integrity. Over-measuring wastes hundreds of dollars in high-grade polymers that flash-cure in the bucket. Worst of all, confusing volume ratios (like 2:1) with weight ratios without compensating for differing component densities causes tacky, un-cured projects or severe exothermic overheating.
We founded EpoxyResin-Calculator.com as an independent engineering resource to give craftsmen, makers, and DIYers an accurate, accessible mathematical modeling engine that operates right in their workshop on any phone, tablet, or desktop.
02Our Core Workshop Principles
Mathematical Precision
We implement true volumetric integration across rectangular river cavities, cylindrical pours, elliptical dishes, and rounded silicone molds, backed by customizable wastage margins (0% to 20%) to account for mixing cup loss and wood grain capillary absorption.
Density-Aware Weight Splits
Resin Part A and Hardener Part B rarely share identical densities. Our engine computes exact gram and ounce splits using manufacturer specific gravities, so you can weigh on digital scales with complete confidence.
Thermal Safety & Exotherm Warnings
Epoxy cross-linking generates exothermic heat. Our interface features built-in safety guidance on maximum recommended single-pour depths, layer stratification, and ambient temperature management to protect your workshop.
Zero-Data Privacy Commitment
Your workshop recipes and project dimensions are your intellectual property. 100% of calculations execute locally in your browser memory. We do not track, log, or store your measurements anywhere.
03Universal Chemical Formulation Support
Our calculator is built to be brand-agnostic and universally compatible with all commercial and craft chemical systems, including:
Compatible with TotalBoat, EcoPoxy, SuperClear, West System, Craft Resin, Liquid Glass, MAS Epoxies, and custom industrial formulations.
