Description
Trimethylolpropane Triacrylate(TMPTA) is a reactive (meth)acrylate component used as a diluent/crosslinker in radiation‑curable formulations to balance viscosity, cure speed, and final film properties.
Uses
UV-curable coatings/inks/adhesives; crosslinker.
Benefits
High crosslink density; improves hardness and chemical resistance.
