low-VOC waterborne polyurethane paints can be formulated that are the equal of solventborne polyurethane paints when used on metal. These coatings are two-component waterborne polyurethanes consisting of a waterborne polyacrylate with a water-dispersible polyisocyanate. The waterborne polyurethane coatings show results equal to, or better than, standard solventborne polyurethane coatings in hardness, impact resistance and solvent resistance. In addition, these waterborne polyurethane coatings show accelerated weathering results that are the equal of standard solventborne polyurethane coatings. Waterborne polyurethane coatings exhibit the best combination of properties and can be used to replace the standard solventborne polyurethane tested.

WL-158 can be diluted with deionized water to construction viscosity. The resin can help to wet pigments, so wetting agent may reduce PH value of the coating system can always be adjusted by N. N-dimthylethanolamine, viscosity of the dispersion will increase as the PH value increases
WL-158 can be mixed with poly aliphatic isocyanate curing agent for preparing high-gloss top coating which can dry fast at room temperature or dry by force at 80"C. The activation period is about 3 hours if it is used with BAYHYDUR 304(NCO/OH=1. 4/1.0).
Construction equipments can be cleaned by water, alkaline detergent or water soluble solvent.
It is suggested that the product should be stored in a cool and dry weak alkaline place. The quality guarantee period is 6 months, and the expired products can still be used after passing the inspections.
2KPU self-drying top coatings and amino-baking top coatings.
