STYRENE/ACRYLATES COPOLYMER- ▸ Film former: Forms continuous films in paints, coatings, and cosmetic emulsions.
- ▸ Binder: Binds pigments and fillers in architectural and industrial coatings.
- ▸ Printing inks: Resin base for water-based ink and overprint systems.
- ▸ Opacifier: Contributes opacity and surface finish in formulated products.
A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Styrene/Acrylates Copolymer (CAS 9010-92-8) is a copolymer of styrene with one or more acrylate or methacrylate esters, typically supplied as an aqueous emulsion or fine powder. The styrene-acrylic class functions as a film former, binder, and opacifying agent in paints, coatings, printing inks, adhesives, and cosmetic emulsions. Film hardness, gloss, and water resistance vary with the styrene-to-acrylate ratio.
Frequently Asked Questions
What is styrene/acrylates copolymer?
Styrene/Acrylates Copolymer (CAS 9010-92-8) is a copolymer of styrene with one or more acrylate or methacrylate esters, typically supplied as an aqueous emulsion or fine powder. The styrene-acrylic class functions as a film former, binder, and opacifying agent across paints, coatings, inks, adhesives, and cosmetic emulsions.
What is styrene/acrylates copolymer used for?
It forms continuous films in paints, coatings, and cosmetic emulsions, binds pigments and fillers in architectural and industrial coatings, serves as the resin base for water-based inks and overprint systems, and contributes opacity and surface finish in formulated products.
What determines film hardness in styrene/acrylic copolymers?
Film hardness, gloss, and water resistance vary with the styrene-to-acrylate ratio: higher styrene content generally gives harder, more water-resistant films, while higher acrylate content gives softer, more flexible films. Specify your performance target when requesting a grade.
Is styrene/acrylates copolymer the same as styrene?
No. Styrene is the monomer; styrene/acrylates copolymer is the finished polymer made by copolymerizing styrene with acrylate or methacrylate esters. The copolymer is a film-forming resin, not a reactive monomer.
How is styrene/acrylates copolymer supplied in bulk?
We supply it to coatings, ink, adhesive, and personal-care manufacturers in bulk packaging suited to the form, such as drums and totes for emulsions or bags for powder. CAS is 9010-92-8. Request a quote with your volume and form for current bulk pricing, CoA, and SDS.
