WL-181C Water Based Saturated Polyester Resin
s
Introduction
WL-181C is waterborne oil-free saturated polyester resin high performance industrial stoving coatings.
Due to its high solids content, coatings can be formulated with very high yields, good gloss, adhesion and excellent flexibility.
Wangqin water-based saturated polyester resins are recommmened to used with amino crosslinkers(Cytec 303 and Cytec 305) and our Acid Catalysts ( cross-linking urea and melamine curing system) to make high-temperature stoving paint,the coating film has high gloss, bright transparency, excellent adhesion on different metals, excellent mechanical properties, good pigment wetting.

Performance Features
Applications
Application Guide
◆ After it 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.
◆ It is a water-dilutable saturated polyester resin, which can be infinitely diluted with deionized water.
◆ The pH value can be adjusted with organic amine or ammonia water, and the viscosity of the emulsion will increase with the increase in pH value.
Storage Condition
