Advantages of epoxy resin board

1. Strong adhesion

The inherent polar hydroxyl groups and ether bonds in the molecular chain of epoxy resins make it highly adhesive to various substances. The shrinkage of epoxy resin is low when curing, and the internal stress generated is small, which also helps to improve the adhesion strength.

2. Strong shrinkage

The reaction between the epoxy resin and the curing agent used is carried out by direct addition reaction or ring-opening polymerization reaction of epoxy groups in the resin molecule, and no water or other volatile by-products are emitted. Compared with unsaturated polyester resins and phenolic resins, they show very low shrinkage (less than 2%) during curing.

3. Electrical performance

The cured epoxy resin system is an excellent insulating material with high dielectric properties, surface leakage resistance, and arc resistance.

4. Mechanical properties

The cured epoxy resin system has excellent mechanical properties.

5. Chemical stability

Generally, the cured epoxy resin system has excellent alkali resistance, acid resistance and solvent resistance. Like other properties of the cured epoxy system, the chemical stability also depends on the selected resin and curing agent. Appropriate selection of epoxy resin and curing agent can make it have special chemical stability.

6. Dimensional stability

The combination of many of the above properties gives the epoxy resin system outstanding dimensional stability and durability.

7. mold resistance

The cured epoxy resin system is resistant to most molds and can be used in harsh tropical conditions.
