Carbodiimide crosslinkers are an excellent alternative for more hazardous isocyanate and aziridine crosslinkers. The carbodiimide crosslinkers are an ideal way to add additional properties to a waterborne coating or lacker.The crosslinkers are part of the STAHL EVO Permutex® portfolio:
- Friendly labelled
- Improved pot life
- Not moisture sensitive
- Fast curing speed upon drying
- Low viscosity & easy to use
Unique crosslinkers for a denser network
Crosslinkers are chemicals that react with various binders or with themselves to improve the physical and chemical properties of a coating. There are two major mechanisms by which crosslinkers can react: by reacting with a polymer or by reacting with themselves forming a so called interpenetrating network with the polymeric binder. The result? A much denser network, which is key in achieving improved performance in resistance against cleaning liquids, sun cream lotions, food stains and other chemicals.
- Increased strength and hardness
- Improved abrasion resistance
- Improved chemical resistance
- Improved hydrolytical resistance (degradation by water)
- Increased adhesion to substrates
Due to the high reactivity of crosslinker molecules it is important to consider the limited pot life of a formulated finish or coating after the addition of a crosslinker.
Next to our water-based Permutex® carbodiimide crosslinker system, we offer crosslinker systems based on the following chemistries:
- Melamine resins
