Advances in surface appearance, production efficiencies and overall part quality are required to keep thermoset composites competitive as key materials for the automotive industry. In response to these challenges, a versatile molding resin has been designed to meet the demanding requirements of the Nineties. Polyester resin MR 13006 lends itself well to the production of SMC, TMC and BMC molded parts. Class A surfaces have been obtained consistently with combinations of MR 13006 and Neulon T PlusR. DiffractoR and LoriaR readings under 85 along with good mechanical properties are achievable. Compounds formulated with the MR 13006/Neulon T PlusR combination can be molded by either compression or injection techniques, and they are characterized by fast cure rates and wide molding “windows.” High-quality surfaces can be obtained with a range of formulations and molding conditions, making these systems very well suited to commercial molding operations.
