ZOLDINE™ XLSE is a multifunctional carbodiimide used in industrial coatings for wood, leather finishing, plastics, waterborne inks, adhesives and metal.

An I2/CHP-mediated cross-coupling reaction of isocyanides with readily accessible amines gives carbodiimides in good yields. This metal-free strategy for. Carbodiimide is a functional group represented by -N=C=N- and compounds having carbodiimide groups are used in various applications thanks to their. Carbodiimides crosslinkers react with carboxyls to form an intermediate that can stabilize upon reaction with amines, forming a peptidic bond, without spacer.

Carbodiimide compounds provide the most popular and versatile method for labeling or crosslinking to carboxylic acids. The most readily available and commonly. Carbodiimide-mediated peptide coupling remains to the most frequently used technique. As a major advantage, carbodiimides do not require prior activation of. Methanediimine is a carbodiimide in which both nitrogens are unsubstituted. Compounds with the general formula RN=C=NR, where R is a hydrocarbyl group.

Carbodiimide compounds provide the most popular and versatile method for labeling or crosslinking to carboxylic acids. The most readily available and commonly used carbodiimides are the water-soluble EDC for aqueous crosslinking and the water-insoluble DCC for non-aqueous organic synthesis methods. CARBODILITE Waterborne crosslinking agents are waterborne polycarbodiimide resin which contains carbodiimide group [-N=C=N-] with hydrophilic segments. CARBODILITE Waterborne crosslinking agents are low-toxic, highly reactive crosslinking agents that react with carboxy group. They can be cured at room temperature or higher if faster reaction is.
