Description
Material Notes:
MPG-D70A is room-temperature-curable polyurethane casting elastomer system designed for molding polyurethane parts with tough, but flexible physical characteristics. The typical applications for this formulation includes prototyping, casing, and in-house tool making. The components for this formulation have low viscosity, which is an advantage to fill thinner parts of the mold; it helps recreating the fine resolution of the mold surface pattern, and avoids trapping large air bubbles. Relatively forgiving pot-life and short demolding time helps the production rate when it is use in a project with a larger production quantity requirement.Information provided by Northstar Polymers.
