When purchasing water-based color paste, we need to understand the system of water-based color paste. Generally speaking, this water-based color paste system is mainly a resin-free system with high pigment content. It has the advantages of high pigment content, strong tinting power, good color development performance, good compatibility, and thixotropic fluidity. However, due to It does not contain resin itself, which can easily lead to poor compatibility between additives and fillers or pigments, resulting in floating colors. So how can we avoid the problem of floating colors in water-based resin-free colorants Woolen cloth?
Resin-free water-based color pastes in some weakly dispersed system coatings can easily cause blooming due to slight differences in fluidity of various pigments and fillers during film formation. This floating color can be solved by adding high molecular weight polymers with multiple anchor groups as color paste wetting agents and dispersing aids to the system. If the resin-free water-based color paste does not match the additives of the resin-free system during use, resulting in floating color, then you can only find other matching water-based color pastes to replace it.
We believe that directly cooperating with water-based color paste manufacturers is a good way to solve the problem of floating color in industrial water-based coatings:
1. You can choose different models of color paste products from different water-based color paste manufacturers for comparison and judgment!
2. Industrial coating paint engineers should directly choose water-based color paste instead of dry powder pigments, so that engineers from the water-based color paste manufacturer can assist in solving the floating color of water-based industrial paint.
3. Water-based color paste manufacturers have many different types of water-based color paste products. Shanghai Caisheng has more than 300 water-based color pastes, including resin-free water-based color pastes, color pastes suitable for different resin systems, and single-color water-based color pastes. Color pastes and compound color paste products are also available, which is more conducive for engineers of industrial coatings and paints to find water-based color paste products that are better compatible with their own industrial paint systems.
