Unsaturated Polyester Resin
TH-120P-1
TH - Tianhe Resin Series
Tianhe TH-120P-1 is a pre-promoted bisphenol A epoxy vinyl ester resin. The low viscosity pre-promoted resin is extremely suitable for vacuum infusion molding processes, while also providing excellent glass fiber wetting effects and its own degassing effect. Compared to similar types of resins, TH-120P-1 has a higher solid content, better wettability, improved fatigue resistance and water resistance, and extremely low volume shrinkage.
