RelcaLink® and Permutex® Crosslinkers for Elastomer Coatings
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 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
- Excellent anti-blocking properties
- Squeak and itch suppression
- High crosslink density
- Rapid curing
- High chemical resistance
- Soft and flexible
- Enhanced adhesion
High-performance Permutex® crosslinker solutions
Apart from RelcaLink®, Stahl offers water-based and solvent-based Permutex® crosslinker systems based on different chemistries:
- Carbodiimide
- Isocyanate
- Melamine
- Aziridine
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 polycarbodiimide crosslinker 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.
Key Benefits
- Rapid curing
- High crosslink density
- Good anti-blocking properties
- Increased strength, hardness, adhesion and chemical resistance
- Enhanced adhesion
- Long pot-life
