Built for the decision before the purchase.
EpoxyCalc is an independent epoxy planning tool. It does not manufacture resin and it does not hold inventory. The goal is simple: turn a real project into a useful quantity, technical fit and purchase plan before money is spent.
Why it exists
A basic volume calculator can tell you how many liters or gallons fit inside a shape. It cannot tell you whether a specific epoxy is designed for that pour depth, whether the room temperature changes the manufacturer's limit, or which combination of available kits covers the project with less unnecessary resin.
How product data is handled
Product specifications are added from manufacturer sources and carry a verification date. Where manufacturers publish project-specific or temperature-specific limits, EpoxyCalc stores those limits rather than replacing them with one generic rule. Conflicting or incomplete data can be shown as incomplete instead of being guessed.
How the site makes money
Some merchant links may become affiliate links, which can generate a commission when a purchase is made. Technical compatibility and the geometry calculation are kept separate from that relationship.
What EpoxyCalc is building
The long-term goal is a practical product-intelligence layer for epoxy: calculate the project first, identify technically compatible systems, compare verified kit sizes and prices, and make the assumptions visible. New calculators and products are added only when the underlying data can be represented without inventing specifications.
No fake reviews
EpoxyCalc is designed around measurable project inputs and published product specifications, not anonymous claims that a product is "best" without explaining why. Commercial badges such as Best Value are only shown when the pricing data used for the comparison is sufficiently complete and recent.
