Improved Chemical Components for Formulating Fiberglass-Reinforced Plastic Soil Surfacings.
Abstract
A stabilized resin was formulated which displayed a shelf life by accelerated test methods substantially in excess of 5 years at 75 F. It was discovered that 2,4-dinitrophenol and p-tolyhydroquinone act synergistically to enhance stabilization. A new, reliable catalyst system was developed that gives reliable cure with adjustable gel times over a temperature range of 40 F to 120 F. The catalyst is cumene hydroperoxide (CHP) and the promoter is a solution of Vanadium Ten Cem (5% metal) and N,N-dimethyl-p-toluidine in a 2.4/2.0 ratio by volume. The newly developed formuation uses components with longer shelf lives is useable over a wider temperature range, and results in better FRP properties. (Author)
