PR-1527-M Potting and Molding Compound

PR-1527-M is a chemically curing polyurethane compound supplied in two-part quantities or premixed and frozen. It cures at 180°F to a tough rubber with a Shore A hardness of 80. It withstands temperatures up to 300°F and has excellent flexibility at -70°F. The viscosity allows easy degassing and excellent flow in encapsulating and potting applications.

Product Details

PPG PR-1527-M is a chemically curing polyurethane compound which may be supplied in two-part quantities or premixed and frozen in plastic cartridges. PR-1527-M cures at 180°F (82° C) to a tough, flexible, cold flow-resistant, high tensile strength rubber with a Shore A hardness of 80. PR-1527-M will cure at 75°F (24°C), but the resultant physical properties will be lower than when heat cured. Properly cured PR-1527-M is designed to withstand temperatures as high as 300°F (149°C) for prolonged periods without blowing, deterioration or loss in electrical properties and has excellent flexibility at -70°F (-57°C).

The viscosity of PR-1527-M allows the material to be degassed easily when supplied in two-part units and provides for excellent flow characteristics in encapsulating, molding and potting applications.

PPG PR-1527-M must be used with a primer on metal, neoprene and polyvinyl chloride surfaces.
