Regular size: 1000mm*2000mm

Product Features

1. Various forms. A wide variety of resins, curing agents, and modifier systems are available to suit virtually every application's form requirements, ranging from very low viscosities to high melting point solids.
2. Easy to cure. Epoxy resin system can be cured in the temperature range of 0~180ºC.
3. Strong adhesion. Epoxy resins have low shrinkage when cured and generate little internal stress, which also contributes to improved adhesion strength.
4. Low shrinkage. The curing agent reacts without the evolution of water or other volatile by-products. Very low shrinkage (less than 2%) during curing.
5. Mechanical properties. The cured epoxy resin system has excellent mechanical properties.
