Alpha/Owens-Corning`s Ultryl{trademark} resin is a new Class A SMC resin that displays interesting and versatile characteristics. First, this resin system can be formulated to make Class A automotive exterior body panels, using conventional molding pressures, that display excellent surfaces in both horizontal and vertical walls. Other attributes of this resin include excellent paint and bond adhesion, good flow in the tool, and mechanical properties that compare favorably to automotive Class A specifications. Second, this resin can be formulated to be used at low pressure, as low as 2.1 MPa (300 psi), to produce parts with Class A surfaces without sacrificing the aforementioned attributes. Large truck parts (greater than 45 kilograms) have been successfully molded under low pressures using this resin. Additional benefits of this resin in low pressure formulations include ease of compounding on existing equipment, excellent material flow in the tool, good glass carry, low porosity, and satisfactory handling compound.
