What is the material of epoxy board? Epoxy board (epoxy resin board), also known as epoxy phenolic glass board, is made of epoxy resin bonding, heating and pressing, with high mechanical properties, stable electrical properties, and good moisture resistance and heat resistance. It contains active epoxy groups, which can be cross-linked with various curing agents to form non-melt, insoluble and other characteristics.
What are the advantages of epoxy resin board?
1. Epoxy board has good mechanical properties. After the epoxy board is cured, the internal structure system changes, so that it has good mechanical properties.
2. The curing of the epoxy board is convenient. Epoxy resin systems can be cured in a temperature range of ~180°C using almost any curing agent. 3. Epoxy boards come in various forms. Epoxy boards come in a variety of forms. Various resins. Curing Agents From very low viscosity to high melting point solids, the modifier system can meet the form requirements of various applications.
4. The adhesion of the epoxy board is very strong. The presence of polar hydroxyl groups and ether bonds in the epoxy resin molecular chain has a high adhesion to various substances. Epoxy resin has low curing shrinkage and small internal stress, which also helps to improve adhesion.
5. The shrinkage of epoxy board is low. The reaction of the epoxy resin with the curing agent is carried out through the direct addition reaction or ring-opening polymerization of the epoxy group in the resin molecule, releasing anhydrous or other volatile by-products. Unsaturated polyester resins. Phenolic resins exhibit very low shrinkage (less than 2%) during curing.
