Properties / Applications: Bayhydur® XP 2487/1 is a crosslinking agent for waterborne systems from which reliable incorporation and high chemical resistance are required. The dispersibility of the product in water is influenced by organic cosolvents. The use of highly hydrophobic or highly hydrophilic cosolvents such as butyl acetate, xylene, butyl glycol acetate, dimethyl formamide or N-methylpyrrolidone generally leads to a coarser dispersion, which may cause turbidity in the coating film depending on the entire system. On the other hand, the use of, for example, methyl ethyl ketone, methoxypropyl acetate, dipropylene glycol dimethyl ether, propylene glycol diacetate or dicarboxylic acid diester mixtures leads to fine-particle dispersions. Combinations with OH-functional dispersions, e.g. Bayhydrol® A 145, A 242, A 2427, A XP 2469, A 2470, A 2139/2 and A 2290 are particularly well suited.
