Trojan Fibreglass uses two methods for mixing ratios, all polyester and vinylester resins are measured by weight. And epoxy resins are measured by volume. Epoxy resins can be measured by weight, but due to the nature of specific gravity of the resin it is important to follow the ratio guide, and the use of electronic scales is essential.
17 Ιουλ 2017 · Getting comfortable with the mixing and application of resin and hardener is the key to a successful fiber-glassing project. Too much resin and the repair will be mush, but too much hardener and the project is over before it ever begins.

24 Νοε 2023 · Typically, the most common mixing ratio is 1:1, implying an equal mix of resin and hardener. However, not all resins mix the same way because different resins have different formulations and properties. Some products may require a 2:1 or 3:1 ratio, while others may call for a 5:1 ratio.
The resin side is typically designated as the ‘A’ side. The ‘B’ side is the hardener side. It comes in a variety of mix ratios including 2:1 or 4:1 ratios by weight or volume. For example, a gallon of Part A would require a half gallon of Part B with a 2:1 by weight system.
Check the hardener label or the technical data sheet for the correct mix ratio of resin to hardener. Whether you’re applying the epoxy mixture to wet out fiberglass, as a coating or a casting, the following steps will ensure a controlled and thorough chemical transition to a high-strength epoxy solid.
The resin to hardener mixing ratio will be so much of part a, (the resin) mixed with so much of part b (the hardener). Once mixed, these two parts make a chemical reaction so your resin is pourable and will cure to a hard, clear, glossy finish.
