How We Calculate This

How the Calculation Works

By volume: The total volume is divided according to the ratio. For 1:1, each component is half. For 2:1, resin is 2/3 and hardener is 1/3.

By weight: The total volume is first converted to weight using a density of 1.1 g/ml (typical for mixed epoxy). Then the weight is divided according to the ratio.
