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.
