Waterborne polyurethane coatings provide the high level of protection and appealing appearance expected from conventional solventborne systems. They also provide very low solvent content and significantly reduced solvent emissions.
Bayhydrol HD products are hydroxyl-functional acrylic resins dispersed in water and can be used as a co-reactants with Bayhydur water-dispersible polyisocyanates in the formulation of < 50g/l VOC coatings. These products can also be combined with other water-reducible binders.
Coatings formulated with Bayhydrol HD 2016 and Bayhydrol HD 2017 along with suitable polyisocyanates (such as Bayhydur HD 2018), have chemical resistance and durability and are suitable for highly durable architectural wall coatings which can exhibit:
• High durability even in eggshell or flat finishes
• Excellent chemical and disinfectant resistance
• Very low odor during installation and drying
• Exceeds the protocol for MPI 252 and MPI 254 paint standards
