ISOPOLYESTER RESINS, WHICH MAY BE USED IN PULTRUDED FIBERGLASS PRODUCTS, HAVE BEEN DEVELOPED. THESE RESINS HAVE PROCESSING AND PHYSICAL PROPERTY CHARACTERISTICS SIMILAR TO COMMERCIAL ISOPOLYESTER RESINS RECOMMENDED FOR THE PULTRUSION PROCESS. A COMPARISON OF THESE RESINS TO TWO COMMERCIAL VINYL ESTER RESINS INDICATES THE ISOPOLYESTERS HAVE EQUIVALENT STRENGTH PROPERTIES TO THE VINYL ESTER RESINS IN THE DIRECTION OF THE GLASS AND IN THE TRANSVERSE DIRECTION TO THE REINFORCEMENT. EVALUATION OF THE PHYSICAL STRENGTHS, WEATHERING CHARACTERISTICS, AND UPPER USE TEMPERATURES SHOW ISOPOLYESTERS AS THE RESINS OF CHOICE FOR MOST PULTRUSION APPLICATIONS.
