Polycarbodiimides as classification-free and easy to use crosslinkers for water-based coatings
By Dr. A.J. Derksen, Stahl International bv, The Netherlands
Crosslinking is widely practiced in nearly all of the coatings industries in order to improve the performance of the coating. These improvements include wear, abrasion and chemical resistances and toughness. The improved performance originates from the formation of a continuous three-dimensional network, which may be formed by the crosslinker alone, or by reaction of the crosslinker with the binder.
Stahl successfully examined the use of polycarbodiimides as a sustainable crosslinker to improve the performance of coatings. Check the results for different substrates, pH and pot life effects.
