Product Description

Waterborne Acrylic Modified Saturated Polyester Resin 

 

Water based saturated polyester resin is used in a wide range of industrial applications, such as coil coating, can coating and other industrial OEM baking applications. It can be crosslinked with conventional melamine resins, urea formaldehyde resins or blocked isocyanate resins designed for water based systems. It is already neutralized, and ready to use. Formulation is easy. It has excellent result for primer, top coat and clear varnish

 

 

Product Features:

  1. low odor, low VOC
  2. Non yellowing
  3. High hardness (over 4H)
  4. Excellent solvent and chemical resistance
  5. High fullness,good flexibility,good gloss
  6. Can use spraying, rolling coating, brushing
  7. Good adhesion to metal surface

 

It is recommended for hardware accessories, car wheel drum, high-grade wood paint and other industrial fields.

3, Product Properties:

Good hardness (>4H), high gloss;

Good flexibility;

Good solvent resistance;

Low temperature fast cross-linking (110℃. 20minutes);

Excellent shear stability, can be grinded with dispersions directly.

4, Instructions:

WL-185 can be diluted with water after neutralization by N,N-dimethyl ethanolamine the amount of which is about 4-5%of WL-185.It has tocombine waterborne amino resin to make baking coating. The suggested amount is about 20-30% of WL-185 by weight. The baking temperatureis above 120℃. The baking conditions and film properties are related with the amino resins used. Right amount of waterborne acidic catalysts canbe added when using methyl etherified amino resin(recommended adding amount is 0.5-1% of WL-185), which can accelerate solidifying.

PH value of the coating system can always be adjusted with organic amine or ammonia. Viscosity of the dispersion will increase as the PH valueincreases. The resin can help to wet pigments, so wetting agent may reduce.

5, Storage:

It is suggested that the product should be stored in a cool and dry weak alkaline place. The quality guarantee period is 6 months, and the expiredproducts can still be used after passing the inspections.

6, Applications:

Amino-baking top coatings.
