3, Product Features:

a) High hardness (over 4H)

b) Good weathering resistance

c) High fullness, good flexibility, good gloss

d) Excellent shear stability, can be grinded with dispersions directly.

The product can be stably stored in PH value 8.5-9.5,It will be setting stratification under the acidic condition.It is particularly evident when adding acidic pigments.The PH value can be adjusted by organic amines,and the viscosity of emulsion will increase of PH value.


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-183. It has to combine waterborne amino resin to make baking coating. The suggested amount is about 15-50% of WL-183 by weight. The baking conditions and film properties are related with the amino resins used. Right amount of waterborne acidic catalysts can be added when using methyl etherified amino resin (recommended adding amount is 0.5-1% of WL-183), 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 value increases. 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 expired products can still be used after passing the inspections.

6, Applications:

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