NeoAdd™ Low-toxicity crosslinker for waterborn industrial coating systems


Across the coatings industry, crosslinkers are utilized to deliver high levels of strength, resistance, and durability required for the toughest applications – but these highly reactive crosslinkers often come with serious health risks that limit their use in specific applications. Until now, low-toxicity alternatives have struggled to achieve comparable performance. The solution? The DSM breakthrough innovation NeoAdd™ PAX enables high-performance, low-toxicity crosslinking for waterborne systems – protecting both surfaces and society.

  • NeoAdd™ PAX-523

NeoAdd™ PAX-523 is a low toxicity (non-genotoxic and non-mutagenic), multifunctional polymeric aziridine crosslinker for reaction with carboxylic acid functional waterborne acrylic emulsions or urethane dispersions at a use rate of 4-8% (wt/wt).


  • NeoAdd™ PAX-523 is specifically designed for use in waterborne industrial and architectural coating systems where superior performance is required.
  • In water-based paints, lacquers, coatings, and adhesives to improve water, alcohol, detergent, chemical and humidity resistance and/or to enhance (wet) adhesion to specific substrates.
  • In water-based industrial wood, floor coatings and parquet lacquers to improve chemical resistance and mechanical properties.
  • In leather and textile coatings to improve detergent and scuff resistance.
