EasyFlo 60 Liquid Plastic is a two-part, liquid polyurethane resin that cures (RTV) to a white, Shore D65 plastic. This product has a simple 1A:1B mix ratio by volume and a fast demold time of 15 to 30 minutes. EasyFlo 60 is a super low-viscosity, pourable plastic, but it can be easily thickened with PolyFiber II Thickener for brush-on application.
