Polyester Resins

Unsaturated Polyester Resins

Unsaturated polyester resins are thermosetting resins produced by the reaction of polyesterification between dicarboxylic acids (saturated and unsaturated) and glycols. The final mixture is obtained by dissolving the resulting resin (a solid polymer at room temperature) in an unsaturated and reactive solvent, normally styrene.

The crosslinking reaction is obtained by the addition of organic peroxide which acts as an initiator, leading to the formation of a complex three-dimensional network generating a solid irreversible state.

The applications of the unsaturated polyester resin are varied. The polyester resins in fact represent one of the absolute compounds used in a wide range of industries.
