Northstar Polymers MPP-A70B Polyurethane Casting Resin
Categories:	Polymer; Thermoset; Polyurethane, TS; Thermoset Polyurethane, Elastomer, Unreinforced
Material Notes:	MPP-A70B is a room-temperature curable polyurethane casting resin system formulated to meet typical requirements for concrete-mold making and many other general applications. The mixing ratio is set to be 1:1 by volume for simple metering. Low viscosity values of the component materials help to recreate the fine mold surface resolution. The long pot-life and gradual curing pattern provide more working-time/ open-time for a manual mixing/casting operation. The stiff, but flexible consistency allows holding a heavy load of concrete and other casting material in molds without deforming too much. Its good tensile strength and tear strength helps the longevity of the molds made of this material. MPP-A70B Part-A Component: MPC-022 (Prepolymer) Part-B Component: PPB-020 (Curative) Mixing Ratio: 100: 100 = Part-A: Part-B by Volume (100: 90 by weight) Information provided by Northstar Polymers
