Polyester Resin Styrene Additive

Adding Styrene monomer to unsaturated polyester resin like our Silmar 249B or 250B helps to reduce the viscosity of the resin and makes it easier to work with. 

You can add up to 50% volume styrene to resin but it is recommended to use only as much as you need to reduce the viscosity to retain full cure strength.

Add styrene to Silmar 249B Polyester Resin with Surfacing Wax to make your own poly "gloss resin".

We also recommend adding Styrene to your hotcoat/sanding resin to make gloss resin (lays flatter the thinner it is)

Available in 2 oz, 4 oz, or 16 oz. bottles

Ask a Question
  • Hello, can we add this to a laminate resin for final sanding purposes? Thank you for your time Troy

    No, Surfacing Wax is added to Polyester Laminating Resin to make it sandable. 
    Styrene is added to the sandable resin to thin it and make it a gloss resin that flows out for a flatter finish.

  • Can this be added to UV resin as a thinner?

    Yes Styrene monomer can be used in both UV cure and catalyst cure polyester resin to thin it.
