A Word About How Containers are Filled: The unit of measure for pints, quarts, gallons, and 5 gallon pails denotes container size and not the actual volume of the liquid inside. Products are dispensed by weight, with varying amounts of head space in the can or bottle to accommodate mixing, expansion, and shipping requirements. In the case of epoxies, the available cans in standard sizes will often appear “short” on resin or hardener to accommodate a true ratio.
