Royal DSM has announced the launch of a highly innovative waterborne crosslinker portfolio, NeoAdd™ PAX, with an unparalleled combination of low-toxicity and high-performance profile for adhesive formulations. The new, patent pending DSM polymeric aziridine crosslinker products will drive safety across a wide range of industries and exemplifies DSM’s commitment to using science to develop sustainable solutions that outperform conventional market alternatives.
High-performance Sustainable Aziridines Solution
NeoAdd™ PAX will open new possibilities to a diverse set of markets, including adhesives, industrial, architectural, packaging, ink and leather coatings. The first two products are:
NeoAdd™ PAX-523 – Designed for water-borne adhesives. Improves water-, alcohol-, detergent-, chemical- and humidity resistance. It enhances wet adhesion to specific substrates.
NeoAdd™ PAX-521 – A low-toxicity, non-genotoxic and non-mutagenic polymeric aziridine crosslinker. Improves water-, alcohol-, detergent-, chemical- and humidity resistance. It enhances adhesion to specific substrates. Designed for water-borne adhesives.
Novel Technology Delivers High with Low Toxicity
Around the world, end consumers and regulatory bodies are increasingly concerned by the potential toxicity of crosslinking solutions. 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 planet.
In line with its ambitious commitment to phase out all Chemicals of High Concern from its final products by 2025, DSM has developed a novel polymeric aziridine technology to deliver high levels of processability and functional performance as well as very low toxicity.
NeoAdd™ PAX – Chemical & Water Resistance
NeoAdd™ PAX has unique chemical design and high molecular weight, due to which the product family delivers outstanding chemical and water resistance plus excellent adhesion to a wide range of substrates and requires no stoving or heating after application. It offers key functional performance advantages compared to most carbodiimide-based waterborne coating systems as higher chemical resistance can be achieved at lower dosing levels.
NeoAdd™ PAX is fully REACH compliant and, because of its low toxicity profile, dramatically decreases the labeling requirements compared with conventional aziridine crosslinkers.
“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!” said Jon Cronin, global innovation growth leader DSM coating resins.
