Epoxy systems can be produced in different mixing ratios, the manufacturer should have specified the most accurate mixing ratio for the system he created on the product label, and the user should use these ratios. In epoxy systems, there is no single truth to this situation. The mixing ratio is determined by the properties of the resin and hardeners used by the manufacturer in production, and this ratio may vary in different types of epoxy systems.

If the mixing ratios are determined by weight, the mixture must be made using a balance. If the mixing ratio is determined as volume, mixing can be done using volume containers. Because epoxy resins and epoxy hardeners have different specific gravity, it is not accurate to measure using volume containers in a system that needs to be calculated by weight. The amount of hardener should not be used less or more than the specified ratio. Increasing the hardener ratio does not cause faster drying, on the contrary, it may cause the system to remain flexible by disrupting the reaction calculation.

Mixing ratios are generally; It is indicated as 1:1 / 2:1 / 3:1 … or 100:100 / 100:50 / 100:33, and the first number is the epoxy resin, the second number is the epoxy hardener. Whatever ratio is specified on the label of the product you use, you should base that value as the multiplier of the mixture you will prepare.

Example 1: Resin To Use = Resin Slim

Labeled Mix Ratio = 2:1

The amount of resin and hardener required for 90 grams of total mixture;

A Component (Epoxy Resin): 60 grams

B Component (Epoxy Hardener): 30 grams

Example 2: Resin to be used = Resin Mass

Labeled Mixing Ratio = 2,5:1

Required amount of resin and hardener for 21 kg of total mixture;

A Component (Epoxy Resin): 15 kg

B Component (Epoxy Hardener): 6 kg
