Measuring & Mixing
How do I measure by volume vs by weight?
Liquid products can easily be measured by volume; paste and solid products must be measured by weight. To measure by volume, the use of disposable cups with graduation marks on the side is adequate. Pour the Part A resin and the Part B hardener on top of each other, in the same container. For measurement by weight, a gram scale (for small batches), or a postal scale(for larger batches) is necessary.

Waxed paper cups.
System Three's wax-lined paper cups are designed for measuring and mixing and not for storage. Most people will mix a volume as needed and apply it to the substrate well before it gets hot. Therefore, the wax coating is negligible. If a longer working time is needed, the contents should be poured into a wide containment such as a plastic paint tray. This will lengthen the pot life of the mixed epoxy and prevent it from getting too hot.
- Why did my epoxy heat up soon after I mixed it?
Epoxy got hot. What happened?
Most of our liquid epoxy products need to be poured out soon after the two parts are mixed together to prevent premature curing, called "exotherm."
