Royal DSM announced the launch of NeoAdd PAX, an innovative crosslinker portfolio which combines low-toxicity and high-performance.
The new polymeric aziridine crosslinker products are patent pending and will find application in a wide range of industries. DSM declared this new portfolio exemplifies the company's commitment to using science to develop sustainable solutions that outperform conventional market alternatives.
"The new NeoAdd PAX crosslinker family aligns perfectly with our purpose-led, performance-driven strategy; this is a sustainable solution that works for both people and planet. Our new crosslinker is a breakthrough innovation in that it competes with traditional aziridines on functional performance but offers significant safety and sustainability benefits to many different industries and markets. I'm very proud that, more than ever, our bright science is being used to enable brighter living", explains Jon Cronin, Global Innovation Growth Leader of DSM Coating Resins.
The potential toxicity of crosslinking solutions are a common concern. Currently available carbodiimide crosslinkers typically offer lower toxicity but compromise functional performance, while traditional aziridine crosslinkers will deliver higher levels of performance but potentially impact the health of people and the planet.
DSM has presented a solution by developing a novel polymeric aziridine technology which combines high levels of processability and functional performance as well as very low toxicity: NeoAdd PAX.
This product family is REACH compliant and, because of its low toxicity profile, decreases the labelling requirements, compared with conventional aziridine crosslinkers. Moreover, its chemical design and high molecular weight ensure water resistance, a higher chemical resistance at lower dosing levels, and excellent adhesion to different substrates, with no stoving or heating needed after application.
NeoAdd PAX finds application in different markets, including industrial, architectural, packaging, ink, adhesives and leather coatings.
The first two products are NeoAdd PAX-523, specially designed for use in waterborne industrial and architectural coating systems where superior performance is required, and NeoAdd PAX-521 for usage in waterborne primers, inks and coatings for packaging applications.
