Styrene Monomer for Polyester Resin | Resineco

Monomer styrene

€10.53
Availability: 9 In Stock

Styrene Monomer: high-quality solvent ideal for polyester resins and gelcoats.

This colorless aromatic liquid is used to reduce resin viscosity, ensuring smoother and more uniform application, and also for cleaning tools in composite processes.

More effective than common solvents such as acetone when working with polyester systems.

Paraffined Styrene for Polyester Resin | Resineco

Paraffinised Styrene

€11.14
Availability: 5 In Stock

Paraffined styrene with 5% paraffin content, ideal as an additive for unsaturated polyester resins. This product eliminates surface tackiness after curing, making sanding and finishing fiberglass parts easier.

It allows converting Gel-Coat into Top-Coat and is especially useful for lamination, repair and surfboard glassing. Recommended dosage is approximately 3% by weight of the resin before adding the catalyst.
