YUKALAC Unsaturated Polyster Resin

YUKALAC Unsaturated Polyster Resin

Unsaturated Polyester Resin (UPR) is a thermoset type polymers. It is made from the polymerization of di-carboxylic acids with glycols. Polymers are dissolved in a reactive monomer such as styrene to produce a liquid with low viscosity. When cured, the monomers react with unsaturated bonds in the polymers and convert them into solid thermoset structure. 

In the composite industry, the use of Unsaturated Polyester Resin (UPR) is approximately 75% of total resins.
