Trimethylolpropane Trimethacrylate with CAS 3290-92-4
What is Trimethylolpropane Trimethacrylate?
Trimethylolpropane trimethacrylate (TMPTMA) is a trifunctional methacrylate monomer featuring three reactive methacrylate groups on a trimethylolpropane backbone. This unique architecture enables dense crosslink network formation during free-radical polymerization, delivering outstanding mechanical, thermal, and chemical resistance in the cured state.
Offered by Runtai Chemical as a colorless to pale yellow transparent liquid with low viscosity and high activity, TMPTMA is compatible with a wide range of acrylic prepolymers and co-monomers. The compound is widely used as a reactive diluent and co-agent in UV/EB-cure systems, PVC plastisols, elastomers, and specialty adhesive formulations.

Product Advantages
- High Crosslink Density: Three reactive methacrylate groups provide rapid, dense network formation that dramatically increases hardness, stiffness and cohesive strength of cured films and composites.
- Low Viscosity, Easy Processing: Compared with higher-functional monomers, TMPTMA maintains a manageable low viscosity, enabling easy incorporation into formulations without thinner additions or heating.
- Excellent Abrasion & Solvent Resistance: Cured TMPTMA networks withstand mechanical wear and chemical attack, making it the go-to choice for industrial coatings on wood, metal, plastic, and PVC surfaces.
- Superior UV/EB Reactivity: High double-bond concentration delivers fast cure speed under UV and electron-beam irradiation—ideal for high-throughput production lines in coatings and printing.
