WL-181 Water-based saturated polyester resin
3H Hardness High Gloss Water Based Saturated Polyester Resin For Amino Stoving Paint
Composition:
WL-181 is a water-dilutable saturated polyester resin, which can be infinitely diluted with deionized water, it can be stored stably under alkaline conditions, and will settle and stratify under acidic conditions, which is especially obvious when acidic pigments are added. Therefore, the diluted resin and finished paint should be stored under weak alkaline conditions. The pH can be adjusted using organic amines or ammonia. The viscosity of the emulsion increases with increasing pH. WL-187 saturated polyester resin has good flexibility and versatility, and it is used for water based amino baking paint.
WL-181 has high hardness (>3H) after cross-linking with water soluble melamine resins, high gloss, fast crosslinking at low temperature, and can be widely used in coil and iron printing industries.

Performance Features
Application Guide
◆ After WL-181 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.
Characteristics
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.
