Product Properties
This hydroxyl acrylic dispersions can be diluted with water to construction viscosity. Its viscosity changes as PH value changes. WQ-WL153 can be mixed with poly aliphatic isocyanate curing agent for preparing high–gloss top coating which can dry fast at room temperature or dry by force at 80?.
The film after curing has high gloss,hardness,limit film thickness and good water resistance.
This product has excellent pigment wetting and shear stability,can be grinded with dispersions directly.
