Unsaturated Polyester Resin

TH-120PT

TH - Tianhe Resin Series

Tianhe TH-120PT is a pre-promoted bisphenol A epoxy vinyl ester resin. The low viscosity pre-promoted, pre-thixotropic resin is extremely suitable for hand lay-up processes to produce large molds, while also having excellent glass fiber wetting effects and its own degassing effect. Compared to similar types of resins, TH-120PT has a higher solid content, better wettability, very low volume shrinkage, and good anti-drip performance.
