Frequently Asked Questions

Why is the exact ratio so important with resin?

Unlike other mixtures, epoxy resin does not cure by evaporation but through a chemical reaction (polymerization). If there is excess resin or hardener, the reaction will be incomplete, leaving the piece sticky, soft or with permanent bubbles.

What is the difference between weight and volume ratio?

Many resins mix 2:1 by volume but 100:45 by weight because the hardener is usually denser. Always use the scale specified by the manufacturer and, if possible, use a digital scale for maximum precision.

How do I avoid bubbles when mixing?

Mix slowly with constant circular movements for at least 3 minutes, scraping the sides of the cup well. Let the mixture rest for a couple of minutes before pouring so bubbles rise to the surface.

What is Pot Life?

It is the time you have to work with the mixture before it starts to harden (gel). In summer or with large volumes, this time is drastically reduced due to the exothermic reaction (generates heat).

# Epoxy Resin Calculation and Mixing Guide

Epoxy resin is not a paint that dries by evaporation; it is a complex exothermic chemical reaction. The magic happens when epoxide molecules chain with polyamine molecules to form a solid crystalline thermosetting polymer.The difference between a lasting piece of art and a sticky disaster lies in exact stoichiometry. An error of just 5% in the mixing ratio can permanently inhibit curing. This tool eliminates the mathematical guesswork, letting you focus on creation.

# Safety Protocol and Best Practices

Ventilation

Although many modern resins are low odor, isocyanate and amine vapors require cross ventilation or an activated carbon mask. Always wear nitrile gloves.
