What is Trimethylolpropane trimethacrylate?
Trimethylolpropane trimethacrylate (CAS 3290-92-4), commonly identified as TMPTMA or by trade names such as Acryester TMP, is a trifunctional methacrylate monomer used as a crosslinking agent.
Where is Trimethylolpropane trimethacrylate used?
- UV- and EB-curable coatings: reactive diluent and crosslinker improving hardness, chemical resistance and cure speed in wood, plastic and metal finishes
- Rubber and tire: co-agent in peroxide vulcanization increasing modulus and heat resistance
- Adhesives and sealants: cohesive strength and dimensional stability under thermal cycling
- Printing inks: fast cure response
- Packaging: improved abrasion resistance
- Its three reactive methacrylate groups enable rapid network formation.
Good to know: Inhibited versions containing polymerization inhibitors are available for storage stability.
Commercial specifications
- Bulk, IBC and drum packaging
