[Chemical Knowledge]：Difference between unsaturated resin and epoxy resin

Read： 583 Time：16months ago Source：Transform the World with Simplicity

Unsaturated resin and epoxy resin are two common resin materials, which are widely used in industrial production. Although they are all resin materials, there are obvious differences in chemical composition, performance characteristics and application fields.

let's take a look at unsaturated resins. Unsaturated resin is a polymer material composed of unsaturated polyester resin and crosslinking agent. It is characterized by short curing time, good weather resistance and strong corrosion resistance. Because of its excellent performance characteristics, unsaturated resin is widely used in FRP products, architectural decoration, shipbuilding and other fields.

and epoxy resin is a thermosetting resin, which is composed of epoxy resin main agent and curing agent. Epoxy resin is characterized by good bonding performance, strong chemical resistance and excellent insulation performance. Therefore, epoxy resin is widely used in electronic components, aerospace, automobile manufacturing and other fields.

in the chemical composition, unsaturated polyester resin is the main component of unsaturated resin, and epoxy resin is the main component of epoxy resin. This determines their differences in performance characteristics and application areas.

In addition, unsaturated resins and epoxy resins also differ in the curing process. Unsaturated resins are usually cured using peroxides or chromium salts as catalysts, while epoxy resins need to be chemically reacted with curing agents to achieve curing. Therefore, the curing process of epoxy resin is more complicated than that of unsaturated resin.

In general, there are obvious differences between unsaturated resins and epoxy resins in chemical composition, performance characteristics and application fields. When selecting materials, the appropriate resin material should be selected according to the specific use requirements. I believe that through the introduction of this article, readers have a clearer understanding of the difference between unsaturated resin and epoxy resin, which will be helpful for future applications.
