EasyFlo 120 Liquid Plastic


EasyFlo 120 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 120 is a super low-viscosity, pourable plastic, but it can be easily thickened with PolyFiber II Thickener for brush-on application. For spray application, consider EasyFlo Spray FR.

EasyFlo 120 has a controlled gelling process that makes it a popular product for rotocasting or slush-casting hollow parts that are incredibly tough and lightweight. These hollow parts are often backfilled with rigid PolyFoam Casting Foam.
