TH-230
TH - Tianhe Resin Series
Tianhe TH-230 is a phenolic type epoxy vinyl ester resin. Compared to the TH-210 product, it maintains good rigidity and strength at higher temperatures, while also exhibiting resistance to acids, organic solvents, and corrosive media, especially in acidic oxidative environments where it has a longer tolerance time. Additionally, its workability is excellent, suitable for various fiberglass molding processes, and widely used in chemical engineering and industry involving numerous chemical media such as acids, bases, salts, and organic solvents. It is an ideal high-temperature fiberglass heavy anti-corrosion resin.
