RelcaLink™ and Permutex® Crosslinkers for Waterborne Coatings

Scroll down to read more

Crosslinkers react with binders or themselves to improve physical properties of the coating. That means they play a vital part in adding properties to a specific coating, such as increased strength, hardness, improved adhesion or chemical resistance. Stahl offers a range of water-based crosslinkers, amongst which our Relcalink™ 10 solution, suitable for improvement of elastomer coatings.


Relcalink™: crosslinker designed for automotive elastomer coatings

Crosslinkers for elastomer coatings such as the more sustainable Relcalink™, help automotive interiors achieve new levels of comfort, safety, style and technical possibilities. For example, using RelcaLink™ 10 enables rapid curing, high crosslink density, squeak and itch suppression and excellent anti-blocking properties. It ensures high chemical resistance, without losing softness and flexibility. Vital qualities the automotive industry is looking for, as each minor advantage offers a competitive edge in driving comfort.

Key Benefits


High-performance Permutex® crosslinker solutions

Apart from RelcaLink™, Stahl offers water-based and solvent-based Permutex® crosslinker systems based on different chemistries:

The crosslinkers in our Permutex® XR portfolio all provide specific properties that make them the best solution for elastomer coatings and materials like EPDM. Permutex® XR-13-554, for instance, is our low-VOC, more sustainable version of the polycarbodiimide crosslinker Permutex® XR-5580 that offers 2-stage extra reactivity for optimum resistance properties, while Permutex® XR-13-621 in its turn is the HAPs-free, multifunctional choice. Permutex® XR-5508, the water-based polycarbodiimide crosslinker is not only VOC-free, but also has an extreme long pot-life, making it the upgraded version of our Permutex® XR-5577.
