Trimethylolpropane Triacrylate

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.
