Description
Material Notes:
MPP-A60A is a room-temperature-cure liquid castable polyurethane system. This ether-base polyurethane system is used in applications such as mold-making, prototyping, production of cast parts, potting, tool-making, and many other applications. MPP-A60A is designed for an easy operation for industrial applications without special casting or heating equipment. Its low viscosity also makes it easy to achieve replicating the details of the mold/original with a fine resolution. Urethane elastomer parts made of this system exhibit: Fine resolution of mold details Good cut/tear resistance for its class Good performance in wet environments Easy-to-use room-temperature-curable Small shrinkage factor The suitable applications of MPP-A60A include stamps/patterns and molds designed to transfer a decorative image to wet surfaces as well as a potting compound for electronic applications where low viscosity liquid resin is required to encapsulate small wires and components. It is also suitable for many other custom applications where flexibility and strength of the parts are required.Information provided by Northstar Polymers.
