WL-182A Waterborne Saturated Polyester Resin
Introduction
WL-182A is a water-based acrylic modified saturated polyester resin, which is used with melamine-formaldehyde resins CYMEL 325 or Cytec 303 to make high-temperature stovin varnish or silver paint. The coating film has high gloss and good fullness, and has an orientation effect on the arrangement of silver powder.

Performance Features
Applications
Application Guide
◆ After WL-182A 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
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.
