BAYHYDUR QUIX 306-70

Ready to use fast curing crosslinker for waterborne systems with easy incorporation and high chemical resistance. Can be easily dispersed in the aqueous phase, even at low shear forces. Gives coatings with high gloss and very low haze. The increase in viscosity during mixing that is typical for hydrophilized hardeners, can be controlled by prethinning with water or organic cosolvent. The dispersibility of the product in water is influenced by cosolvents. The use of highly hydrophobic or highly hydrophilic cosolvents (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. The use of, for example, methyl ethyl ketone, ethoxypropyl acetate, dipropylene glycol dimethyl ether, propylene glycol diacetate or dicarboxylic acid diester mixtures leads to fine-particle dispersions. Certain yellowing can be observed due to the its partial aromatic character.
