Grenada 608N

The Tianhe Dianshi brand DS-600N is an ISO-Phthalic unsaturated polyester resin for trenchless pipeline repair, based on isophthalic/new pentanediol type. Styrene serves as the crosslinking monomer, featuring high reactivity, moderate viscosity, and stability in thickening at room temperature. It has good wetting properties for fiberglass fabrics and fast post-curing characteristics. This results in a prepreg with a long storage life and low styrene odor volatility, making it easy to adhere to pipe walls in various temperature environments. The cured product exhibits high mechanical strength, good toughness, heat resistance, water resistance, corrosion resistance, and excellent weather resistance, making it suitable for CIPP UV curing and CIPP hot water inversion methods for repairing pipe liners.
