What is Vinyl toluene?
Vinyl toluene (CAS 25013-15-4) is a reactive monomer used as a building block in polymer synthesis and resin production.
Where is Vinyl toluene used?
- Coatings: harder, faster-curing films in industrial and architectural finishes
- Printing inks: resin binders with controlled drying speed and adhesion to various substrates
- Adhesives and sealants: copolymer backbones tuned for flexibility, tack, and cohesive strength
- In unsaturated polyester and alkyd resin systems it acts as a reactive diluent and crosslinker, replacing styrene where lower volatility is required.
Good to know: Typically inhibited with a polymerization inhibitor to maintain stability during storage and transport, remaining reactive only when intended during manufacturing.
Commercial specifications
- Bulk liquid supply in drums, IBCs, and isotanks
Other Names (Synonyms)
Benzene, ethenylmethyl-|Styrene, ar-methyl-
