STM PRO Polyurethane Casting Resin 75D is a high quality, low viscosity, odourless, general purpose casting resin for use in model/sculpture casting, pattern making and prototyping/product development. The resin is fast curing, making it ideal for production runs, whilst its low price ensures that even larger castings can be produced cost effectively. Because this resin is slightly thicker than our 60D resin, it is ideal for slush casting in an open face mould.

In conjunction with a silicone mould, STM PRO Polyurethane Casting Resin 75D can be used to produce beautifully detailed sculptures, figurines, RPG character replicas and modifications. In fact just about anything you would like to accurately reproduce in a durable, heat resistant plastic.
