New Low Shrink Polyesters in Reinforced Plastics 680061
A new concept in unsaturated polyester resins now provides exceptionally smooth surfaces on molded glass fiber reinforced structures. The resins have good cure speed and contribute to excellent strength retention of molded parts at elevated temperatures. Premix compounds based on low shrink resin are well suited for injection molding because of an unusual combination of attributes. The use of these unique resins will offer reduced finishing costs for glass mat reinforced moldings and open new “appearance” applications for the versatile premix molding process.
