2023-11-10
1. Features and main uses:
Tianrun TR-197 is A bisphenol A type unsaturated polyester resin (modified), dissolved in styrene. It has medium viscosity and high reactivity, excellent mechanical properties, high thermal deformation temperature and corrosion resistance. It is especially suitable for high mechanical strength and chemical corrosion resistance at high temperatures. Such as ships, chemical equipment, anti-corrosion facilities, etc.
