The excellent polymeric aziridine innovation. A great 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. However, these highly reactive crosslinkers often come with serious risks that limit their use in specific applications. Until now, low-toxicity alternatives have struggled to achieve comparable performance. The solution? Our great innovation NeoAdd® PAX enables high-performance, low-toxicity crosslinking for waterborne systems – better protecting both surfaces and society.
NeoAdd® PAX is not available worldwide yet.
(REACH and China compliant - TSCA & DSL pending).

Keeping people safer

Building on our long tradition of innovating to meet industry needs, a dedicated team of our experts created NeoAdd® PAX.
This game-changing polymeric aziridine product family has all the reactivity and performance of traditional aziridine crosslinkers, without the genotoxic and mutagenic toxicity issues that limit their use – keeping chemical handlers and future generations safer.

Half the labeling

The low-toxicity of NeoAdd® PAX   better protects people’s health. It also 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 is 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 fine 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.

NeoAdd® PAX-521

Ideal for ink manufacturers and converters, NeoAdd® PAX-521 is specially designed for use in water-based inks, lacquers, coatings and adhesives. It is non-genotoxic and non-mutagenic and is expected to be Swiss Ordinance approved*. 
NeoAdd® PAX-521 is supplied as an 80% solution in ethyl acetate for use in various inks and coatings to improve chemical resistance and mechanical properties as well as enhance adhesion.

NeoAdd® PAX-523 

Developed for paint manufacturers, NeoAdd® PAX-523 is specifically designed for use in waterborne industrial and architectural coating systems where great performance is required. 
NeoAdd® PAX-523 is supplied as an 80% solution in methoxy propyl acetate and can be used in a wide range of paints, floor coatings, plus leather and textile coatings to improve their chemical resistance and mechanical properties.

* 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 per end of 2022. 

Easy, efficient processing

But there is 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.

Adhesion that sticks, whatever the substrate

A wide range of coating systems, from inks to packaging and flooring and even industrial OEM, can reliably benefit from the unique properties of NeoAdd® PAX.
Our different crosslinkers deliver good adhesion to a range of substrates and are also excellent adhesion promotors when added to other coatings – performing better than traditional aziridines and carbodiimides.
If your coating is designed for industrial wood, metal, fabric, or leather, NeoAdd® PAX has you covered, again and again.

Benefits of NeoAdd® PAX

Whether you’re a manufacturer looking for high processing efficiency with fewer usage limitations, or a consumer that wants safer, highly durable coatings, NeoAdd® PAX   products are the no-compromise crosslinker for you. Its versatile range of benefits means that you can enjoy game-changing safety and performance standards across the value chain.
