NEOADD PAX-521

NEOADD PAX-521 is a multifunctional polymeric aziridine crosslinker that provides significant improvements in chemical and mechanical resistance properties for various applications. As an additive of 4-8% to carboxylic acid functional waterborne acrylic emulsions or urethane dispersions, NEOADD PAX-521 produces enhanced water, alkali, alcohol and oil resistance as well as improved scratch and rub resistance levels. These properties allow for greater durability and protection in end use scenarios. NEOADD PAX-521 can be added to waterbased formulations above a pH of 7.5 for easy dispersion and handling. It is supplied at approximately 80% active content in ethyl acetate and offers a low toxicity profile.
