Color paste generally causes less paint thickening after addition. The main reasons for the paint viscosity to become high may be:
1. Alkali swelling or polyurethane thickeners are added to the color paste, and a large amount of free water is bound, which affects the fluidity of the paint.
2. The additive components in the color paste do not match the paint system.
When using water-based color paste to color paint, the viscosity of the paint will become thicker. You need to check the compatibility of the color paste and the paint system first. If necessary, you can contact and confirm with the color paste supplier, and ask for corresponding solutions and preventive measures. �
