Application Guide

◆ After WL-187 is neutralized with N, N-dimethylethanolamine( 5~6% of the resin), it can be directly diluted with water.

◆ Add methylated amino resin (20%-30% of the resin) for baking and curing. The baking temperature is above 120°C. The baking conditions and paint film properties are related to the amino resin used. When it used with the fully methylated amino resin, an acid catalyst(0.5-1% of the resin) must be added, and the baking temperature must be above 140°C.



The diluted emulsion of WL-187 has excellent shear stability and can directly participate in the grinding of color paste. Because the structural characteristics of the resin help the wetting of pigments and fillers, no or less wetting agent can be added when the resin is involved in grinding.



Storage Condition

Store the product in a cool and dry place, the recommended storage temperature is 0~40℃. The shelf life is one year. After the expiration date, if the test passed, it still can be used.
