How to mix 1:1 in 750 mL

This calculator treats 1:1 as resin-to-hardener by volume and divides a 750 mL total accordingly. Use the manufacturer’s separate by-weight ratio when it provides one.

  1. Confirm that the manufacturer specifies four parts resin to one part hardener by volume.
  2. Measure the resin and hardener amounts shown in the Exact amounts card.
  3. Combine and mix using the manufacturer’s timing, temperature, and safety instructions.

Accuracy tips

Resin and hardener densities can differ, so a volume ratio must not be assumed to be the same numeric ratio by weight. Use the exact product technical data.

How this is calculated

For a ratio of a:b, each part is a/(a+b) and b/(a+b) of the total. PPM mode uses 1 ppm ≈ 1 mg/L for aqueous solutions. Switch to "Mix by weight" to convert those fractions into gram targets using your provided densities.
