Polyester Resin

Polyester Resin is a type of synthetic resin formed through the reaction between organic acid in a base and polyhydric alcohol. This resin is also known as Unsaturated Polyester Resin (UPR) or Fiberglass Resin. Polyester resin is widely marketed worldwide, particularly in Indonesia, with various colors such as red, white, yellowish, and green, which will appear slightly transparent when applied in relatively thin layers.
