This company has developed a new water-soluble catalyst that has excellent hydrolytic stability and provides enhanced properties in 2K WB PU formulations under a variety of environmental conditions.
Two-component waterborne polyurethane (2K WB PU) coating technologies have been commercially available since 1990 and were primarily developed to address VOC reduction requirements that were not feasible with solvent-based technologies at that time.(1) Since the initial introduction of 2K WB PU technologies, advancements have addressed many of the deficiencies inherent to water-based coatings in an effort to match the performance properties and application latitude of traditional solventborne two-component polyurethane coatings.
