TR-883 Unsaturated Polyester Resin (modified)

2023-11-10

1. Features and main uses:

TR-883 is a vinyl-based unsaturated polyester resin (modified) that is 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, electrical insulation and chemical corrosion resistance at high temperatures. Such as electrical engineering, ships, chemical equipment, anti-corrosion facilities, etc.
