Used in the production of ultraviolet-curable inks, electron beam irradiation-curable coatings, & polymers & resins; as a component of photopolymer & flexographic printing plates & photoresists; & as an ingredient in acrylic glues & anaerobic sealants. Also used in paper & wood impregnates, wire & cable extrusion, polymer-impregnated concrete, & polymer concrete structural composites.

Local:  Trimethylolpropane Triacrylate, trifunctional monomer, is useful in the low volatility and fast cure response. It favors the property of resistance against weather, chemical, water and abrasion. It is used in manufacturing coatings, inks and adhesives. End applications 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.
