RESION EPSafe Polyester resin is specially designed to upholster styrofoam because regular polyester resin affects styrofoam. This special polyester resin can be applied over EPS foam and XPS foam without any problems. After applying a layer of 225 g/m2 glass chopped strand mat and Styrofoam resin, you can continue working with our normal polyester laminating resin.

This eco friendly polyester resin is almost odourless. Consequently, this polyester is also suitable for various other applications.
