Millstone Durbax manufactures and develops Polyfunctional Aziridine Crosslinkers for advanced performance in coatings, adhesives, inks, textiles, films, and leather.

These speciality additives strengthen performance by linking polymers together at the molecular level, creating tougher, more durable, and more resistant finishes.

Our crosslinkers cure quickly at room temperature, deliver outstanding resistance to chemicals, abrasion, and moisture, and achieve excellent results at low dosage levels.

For formulators, they’re a proven alternative to traditional systems such as isocyanates and carbodiimides.

Our Product Range

MY-0104

Chemical structure of Polyaziridine Crosslinker AN-2201 on an orange hexagonal background.

MY-0104 contains alcohol functionality, making it more soluble in water and giving higher crosslink density than AN-2201.

It’s ideal where clarity, toughness, and resistance are priorities, especially in aqueous formulations.

  • Optimised for waterborne systems.

  • Maintains excellent clarity and colour stability.

  • Provides fast curing, with strong water and abrasion resistance.


AN-2201

Chemical structure of Polyaziridine Crosslinker MY-0104 on an orange hexagon background.

AN-2201 is a low-viscosity, low-colour trifunctional Polyaziridine.

It’s well-suited to both aqueous and non-aqueous systems and is often chosen when fast curing and reliable adhesion are needed.

  • Excellent adhesion to plastics, wood, metal, paper, and concrete.

  • Strong chemical, water, and abrasion resistance.

  • Stable room-temperature curing with a practical pot life.


ND-1404

Chemical structure Polyaziridine Crosslinker ND-1404 on an orange hexagonal background.

ND-1404 is a bifunctional Polyaziridine supplied as a 100% active solid or 25% active waterborne dispersion.

It’s activated by heat, making it the right choice for acid-functional coatings, inks, and adhesives where durability is critical.

  • Heat-activated cure at 80–120 °C.

  • Enhances scuff, chemical, and oil resistance.

  • Suitable for leather, varnishes, textiles, and protective coatings.

Together, these crosslinkers give formulators flexibility to choose the right balance of reactivity, resistance, and curing profile.

Whether you need fast room-temperature curing, high crosslink density in waterborne systems, or heat-activated performance, the Millstone Durbax PAXL range delivers reliable solutions backed by consistent quality and global supply.

Applications In Industry

Polyaziridine crosslinkers are used wherever stronger films, faster curing, and improved resistance are required. By reacting with carboxyl groups in acrylics and polyurethanes, they add durability and performance across a wide range of sectors.

  • Coatings and varnishes – tougher wood finishes, protective layers, and clear coats with higher scuff and chemical resistance.

  • Adhesives and pressure-sensitive adhesives – improved cohesion, controlled tack, and reliable curing at room temperature.

  • Printing inks and films – better adhesion to low-energy substrates, increased scuff resistance, and improved clarity and gloss.

  • Textiles and nonwovens – enhanced resistance to water and abrasion, plus anti-wicking properties for long-lasting performance.

  • Leather finishing – greater durability against wear, heel marks, and chemicals while maintaining colour and clarity.

  • Packaging films (BOPP, PET) – primers and coatings that harden for demanding tests, giving gloss, clarity, and excellent printability.

Formulation and Dosage Guidelines

Millstone Durbax crosslinkers are designed for easy incorporation into coatings, adhesives, and inks. They work effectively at low dosage levels, deliver reliable room temperature curing, and perform best in slightly alkaline systems.

Typical pot life and shelf life values vary by product, with full details available in our technical data sheets.
