Trimethylolpropane triacrylate

Trimethylolpropane triacrylate (TMPTA) is a trifunctional acrylate ester 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 properties of weather, chemical and water resistance, as well as good abrasion resistance. End products include alkyd coatings[1], compact discs, hardwood floors, concrete polymers, Dental composites, photolithography, letterpress, screen printing, elastomers, automobile headlamps, acrylics and plastic components for the medical industry.
