Trimethylolpropane triacrylate Usage And Synthesis

Description

Trimethylolpropane triacrylate (TMPTA) is a multifunctional acrylie monomer. It reacts with propyleneimine to form polyfunctional aziridine. Sensitization was observed in a textile fabric printer. Patch tests were positive with the polyfunctional aziridine hardener, but were negative to TMPTA. TMPTA caused contact dermatitis in an optic-fiber manufacturing worker and was reported as a sensitizer in a floor top coat or in photopolymerizable inks.

Chemical Properties

Colorless viscid liquid

Uses

Trimethylol propane triacrylate is a triacrylate for use in UV -curable lithographic inks, varnishes, artificial nails, wood finish solder, and etch resists in the electronics industry.
