TWO COMPONENT WATER REDUCIBLE CHEMICAL RESISTANT COATING

摘要

TWO COMPONENT WATER REDUCIBLE CHEMICAL RESISTANT COATING A two-component chemical resistant, water-reducible coating composition characterized by a VOC level of less than 240 g/l which is the reaction product of (a) an aqueous dispersion of a hydroxy functional polyurethane with an average functionality if at least 1 and a total urethane plus urea group content of from about 9 to about 20% by weight and (b) an aliphatic isocyanate that has been modified by reaction with an amount of monofunctional polyether sufficient to make the isocyanate dispersible in water formed when (a) and (b) are reacted in amounts such that the NCO/OH ratio is from about 0.8:1 to about 10:1.
