Trimethylolpropane triacrylate (TMPTA) is a trifunctional monomer used in the manufacture of plastics, adhesives, acrylic glue, anaerobic sealants, and ink. It is useful for its low volatility and fast cure response. It has the property of resistance against weather, chemical, water and abrasion. End products include alkyd coatings, compact discs, hardwood floors, concrete polymers, dental polymers, lithography, letterpress, screen printing, elastomers, automobile headlamps, acrylics and plastic components for the medical industry.
