Graduated Plastic Mixing Cups - Polypropylene

Use graduated mixing cups to measure resin and hardener or catalyst to the ratio on the label, then stir with a flat stick for at least a minute, scraping the sides and bottom so it blends fully. Epoxy must be measured to its exact ratio and is not forgiving; polyester takes a small percentage of MEKP by volume. Mix only what you can use within the pot life.
