3. High toughness, crack resistance, high heat resistance temperature, excellent strength retention rate at high temperature.
Epoxy vinyl ester resin is prepared by the chemical reaction of epoxy resin and methacrylic acid through ring-opening addition. It retains the basic segment of epoxy resin, and has the good process performance of unsaturated polyester resin. After curing under suitable conditions, it shows some special excellent properties.
Matters needing attention:
1. The transportation shall comply with the regulations on the transportation and handling of hazardous chemicals in Chapter V of the State Council's "Regulations on the Safety Management of Chemical Hazardous Substances".
2. The product should be stored in a cool place below 25ºC, avoid fire and isolate the heat source.
3. The shelf life is 3 months under the specified storage conditions.
