Styrene Thinner

General Purpose Styrene

Styrene is primarily used to thin polyester resin and gel coat before use. This is not a necessary step for the resins or gel coat on, but simply a preference for handling purposes.

  • When added to polyester resin, it enables and speeds the resin infusion process for vacuum bagging.
  • Fabricators may thin gel coat 2–5% with styrene to make them more suitable for heavy spray equipment.
