Crosslinkers to ensure fastness
Crosslinking works by connecting polymers through reactive chemistry, thus strengthening the network of a specific coating. As an addition to coating formulations, they provide a wide range of additional possibilities.
In particular, Stahl’s crosslinkers improve fastness in leather goods, adding high-performance protection to leather for a range of applications. They also offer other beneficial properties such as improved print retention and flexes, encouraging high flexibility, retaining dull finishes, and UV fastness.
Environmentally friendly carbodiimide enhancers
Our range of crosslinkers also includes two carbodiimide crosslinkers, which are much less sensitive to water and have a long pot life. Due to their high reactivity, curing with these crosslinkers can be done at room temperature and under typical oven conditions used for the drying of applied coatings.
Stahl’s crosslinkers are part of our Stahl Neo® portfolio , which means that they comply with the ZDHC MRSL.
