Sinomer® PET3A-CA is a carboxylated 季戊四醇三丙烯酸酯 (PETA) monomer, supplied as a clear to slightly yellow transparent liquid. It is specifically designed to enhance adhesion, hardness, and curing speed in radiation-curable formulations. The presence of carboxylic functionality promotes excellent adhesion to difficult substrates such as metals and plastics, making it ideal for high-performance coatings, inks, and adhesives.
