Pentaerythritol Tetraacrylate (PETA)

Pentaerythritol Tetraacrylate 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/chemical resistance.
