Product Description

Unsaturated resin is a type of thermosetting resin.

It is mainly composed of unsaturated polyester resin and a reactive diluent (usually styrene). The unsaturated polyester resin part contains double bonds in its molecular structure. These double bonds can undergo polymerization reactions.

 

When combined with a curing agent and under certain conditions such as appropriate temperature and time, the double bonds in the unsaturated resin will react and cross-link with each other. This cross-linking process transforms the resin from a liquid or semi-liquid state into a solid, hard and durable material with good mechanical properties, chemical resistance and heat resistance.

 

Unsaturated resins are widely used in various fields, such as in the manufacturing of fiberglass products (like fiberglass reinforced plastics), in the production of castings, and for coating applications due to their versatility and relatively easy processing characteristics.
