Water-Based Acrylic Modified Saturated Polyester Resin For Stoving Varnish

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.

Composition:

Water-based acrylic modified saturated polyester resin, cosolvent

Physical Property

Viscosity *: after dilution with propylene glycol methylether (1:1)

Performance Features

• Good resin stability;
• Low cost, low VOC;
• Excellent shear stability, can be directly used for grinding color paste;
• High solid content, high gloss and good fullness of the coating film;
• Excellent mechanical stability;
• Good orientation of silver powder and can be used for flash paint;
• Excellent adhesion on metal substretes;
• Pigment wetting, high gloss.

Applications

• Used to make high decorative amino baking finish topcoat.
• Used to make amino paint, pigment paint, flash paint, etc.;
• Used in steel drums, wheels, bicycles, electric vehicles and other industries;
• Stoving system paints for general purpose industrial coatings;

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
