411 resin is synthesized by reaction of methacrylic acid, BPA and epoxy resin and has dissolved in styrene solution.
The Product Characteristic
The resin has the characteristics of excellent comprehensive performance, good mechanical properties and forming process.
Good corrosion resistance of the resin make it possible to resist most acid, alkali, salt solution and some solvents under 100ºC.
The resin is suitable for hand lay-up, winding and other FRP molding process.

(2) curing procedure: curing 24 hours at room temperature, curing 2 hours at 120ºC.
The above is the typical test data in accordance with the corresponding NATIONAL standard GB, not as a standard.
- Tolerates heavy design loads without causing failure due to resin damage therefore can work with large weight-bearing equipment with confidence
- Excellent elongation and toughness provides FRP products with better impact resistance and less cracking due to cyclic temperature,pressure fluctuations, and mechanical shocks providing a safety factor against damage during process upsets or during shipping installation.
- High solid content, with excellent mechanical strength and excellent toughness, the composite products made from it shows excellent long-term heat resistance, and high dynamic load bearing performance;
- Excellent toughness, crack resistance, higher heat resistance temperature, excellent strength retention at high temperature.
