What is styrene monomer (CAS 100-42-5) in paint?
In paints and coatings, styrene monomer is primarily used in certain industrial alkyd resins and water-based latex paints.
Alkyd resins: Styrene is copolymerised with alkyd resins to create 'styrenated alkyds'. This significantly speeds up drying time and improves the hardness and water resistance of the coating.
Latex paints: The 'latex' in water-based paints is often a synthetic polymer emulsion. One common type is styrene–acrylic copolymer, which strikes a good balance between durability, water resistance and cost-effectiveness for interior and exterior paints alike.

- Polystyrene (PS):
- High Impact Polystyrene (HIPS)
- Expanded Polystyrene (EPS) & Extruded Polystyrene (XPS):
- Acrylonitrile Butadiene Styrene (ABS):
- Styrene-Acrylonitrile (SAN):
- Synthetic Rubbers:
- Styrene-Butadiene Rubber (SBR):
- Styrene Butadiene Latex (SBL)
- Unsaturated Polyester Resins (UPR):
