What is epoxy resin? How does epoxy work fast?
The difference between polyester resin and alkyd resin is that the raw material of synthetic polyester resin does not contain vegetable oil or fatty acid which is the main component of oil. Polyester can be divided into saturated polyester and unsaturated polyester. Saturated polyester means that the synthetic raw materials do not contain unsaturated bonds other than benzene rings.

Unsaturated polyester resin crosslinked network structure
The double bonds in the unsaturated polyester and the double bonds in the cross-linking agent are polymerized to form an insoluble and infusible cross-linked network, and the network contains two kinds of polymer molecular chain structures. The main body of the network is composed of random coils of unsaturated polyester molecular chains, interspersed with styrene copolymer molecular chains, connecting and fixing the unsaturated polyester molecular chains to form a huge network.
Epoxy resin application field
The excellent physical, mechanical and electrical insulation properties of epoxy resin, its bonding properties with various materials, and its flexibility of use process are not available in other thermosetting plastics. Therefore, it can be made into coatings, composite materials, casting materials, adhesives, molding materials and injection molding materials, and is widely used in various fields of the national economy.
Epoxy resin is an organic chemical. This product is more suitable for use on floors during decoration. At the same time, this product has strong corrosion resistance, and it is also an electrical insulating product. The following small series will introduce to you what epoxy resin is and how epoxy resin can dry quickly.
