A breakthrough innovation for low-toxicity crosslinking

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™ is a DSM patent-pending technology.

Half the labeling

The low-toxicity of NeoAdd™ PAX doesn’t just protect people’s health – it allows formulators, converters, and manufacturers to dramatically reduce the number of safety labels on their finished products compared with traditional aziridines.

Reducing these labeling requirements opens new high-performance possibilities for the coatings industry worldwide.

Performance you can rely on

Many low-toxicity crosslinkers fail to deliver the high functional performance consumers require. That’s not the case with NeoAdd™ PAX – it offers key functional performance advantages compared to most carbodiimide based waterborne coating systems such as better chemical resistance even at lower dosing levels. NeoAdd™ PAX achieves this high functional performance whether coatings are cured at room temperature or under stoving conditions, which is a shortcoming of carbodiimides. Additionally, our unique crosslinkers enable excellent water resistance as well as great scuff and abrasion resistance. For a coating you can rely on, NeoAdd™ PAX is the clear choice.

* Toxicological tests (Ames and Toxtracker) have proven that NeoAdd™ PAX-521 and NeoAdd™ PAX-523 are non-genotoxic alternatives to crosslinkers currently in use. These test results were used as a basis for our petition to the Swiss Authorities regarding the polymer(s) in this product. We are expecting a positive response from the Swiss Authorities prior to November 30, 2020.

Easy, efficient processing

But there’s more. NeoAdd™ PAX products are  operational over a wide temperature range and can be cured at room temperature, so stoving curing ovens are not required.

They also have excellent pot life, thanks to high stability in water – driving processing efficiency, and saving money, time, and energy.

Turn down your ovens and turn up the performance.
