The problem with traditional crosslinkers 
Crosslinking involves connecting polymers through reactive chemistry to enhance key mechanical properties, such as adhesion, toughness, abrasion, and chemical resistance. However, reactive groups of traditional crosslinkers (aziridines, isocyanates, and melamines) are potentially harmful, irritating, sensitizing, or even toxic to humans and the environment.

In particular, the use of aziridines is falling significantly in specific applications due to their toxicity, handling limitations, and serious health risks for employees and customers. Even the latest aziridine market developments are still classified. Traditional crosslinkers also present drawbacks in terms of their technical performance. For example, commonly used isocyanates offer a limited pot life and high sensitivity to moisture.

Why leading coating producers are choosing carbodiimide crosslinkers

Carbodiimide crosslinkers (CDIs) are a safe, high-performance alternative to more hazardous traditional crosslinkers. Carbodiimides are defined as non-hazardous under the Global Harmonized System (GHS). Furthermore, standard CDIs react at low temperature and offer an extended pot life. This makes them easy-to-use to formulate high-performance inks, paints, and coatings, from do-it-yourself to high-end industrial applications.

Key benefits of CDIs

Let Stahl support your transition to CDIs

Stahl Polymers has supported leading global coating producers in their transition from traditional isocyanates and aziridines to carbodiimide technology. We’re ready to help you make the switch too.
