Product Description
Brief introduction:
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.
Features:
The standard bisphenol A epoxy vinyl resin is a vinyl resin synthesized by the reaction of methacrylic acid and bisphenol A epoxy resin. It has been dissolved in styrene solution. The specific molecular structure is shown in the figure below.
Properties:
INV-V440 is a pre-accelerated, pre-thixotropic, low shrinkage vinyl resin with the following characteristics:
1. Good glass fiber wettability, convenient construction;
2. Low shrinkage, good dimensional stability and smooth surface;
3. High toughness, crack resistance, high heat resistance temperature, and excellent strength retention rate at high temperature.
