Abstract
Aluminum organic thickeners have been developed for use as thickening agents for thermoset sheet molding compounds and bulk molding compounds. The role of the thickening agent is to control the viscosity of the molding compounds throughout the production processes. The thickeners include an aluminum chelate complex, 10% to 50% by weight of a polyester or polyester acrylate carrier resin, and 10% to 50% by weight of a diluent such as a petroleum distillate. A molding compound includes an aluminum chelate complex thickening agent, a thermosetting resin, reinforcing fibers or microspheres, a crosslinking initiator, and an inhibitor. A method of making a molding compound, such as SMC or BMC with the improved thickener is also provided.
