Proposed dosage
CX-138
CX-138 is a controlled flocculation wetting and dispersing agent for solvent-based medium to high polarity coatings, preventing the floating color and mottling of titanium dioxide when mixed with colored pigments. It contains silicone to improve the floating color and mottling behavior.
Product advantages
Effectively prevents floating color, mottling, as well as sedimentation and sagging.
In many cases, when used as an anti-corrosion primer, the anti-corrosion performance is improved.
Enhance surface smoothness and leveling, as well as the orientation of matting powder and aluminum powder pigments;
In most cases, there is no need to add the silicone additives that must be used in the regular formula.
