Tooling resin is a polyester laminating resin that is used with an alumina trihydrate filler to cut cost and time in tool production. This resin has a very low shrinkage and a rapid barcol hardness. It also allows the tool to withstand heat. Each kit contains 5 Gallons of Tooling Resin, 50lbs of Alumina Trihydrate (ATH) filler, and 8 oz of MEKP9 Hardener.
