The Cost/Performance Advantages of Isophthalic Acid Based Unsaturated Polyesters in Gel Coated Laminates

摘要

The use of isophthalic acid-based unsaturated polyester (isopolyester) in the laminate has been shown to increase the blister resistance of the system, compared to phthalic anhydride-based unsaturated polyesters (orthopolyester). Furthermore, isopolyesters are tougher and offer greater fatigue resistance than orthopolyesters.
