Base color paste to tell you about water-based color paste those things
With the development of the coating industry, the color class raw materials for coatings – color paste is also growing rapidly, there are actually many domestic manufacturers are doing color paste, but in the face of numerous color paste brands, although it gives coating companies a wide choice of space, but due to the different quality of color paste to our choice has also increased the difficulty.
Our company has been focusing on the R&D and production of paint color paste for more than ten years, and has developed into many industries such as paper, industry, latex, etc. We are a comprehensive manufacturer integrating R&D, production and sales.
Today, we will talk about the water-based color paste.
Water-based color paste is water as the dispersion medium, organic or inorganic pigments in the wetting and dispersing effect of surfactants (can also add water-soluble resin) dispersed in water. It forms a homogeneous, stable and concentrated pigment paste with high coloring power with certain fluidity. There are two kinds of water-based color paste systems: one is a high pigment content resin-free system; the other is a low pigment content resin (general-purpose resin, other single resin) system. The former has high pigment concentration, strong coloring power, good color spreading performance, good compatibility, thixotropic fluidity, will not cause floating color and flowering, reasonable choice of additives, and is universal. The latter has relatively low pigment concentration, but has good coloring power, good color spreading, stable fluidity and viscosity, the system contains resin, compatibility needs to be tested, otherwise it is easy to lead to paint floating color.
Water-based pigment paste is a kind of concentrated pigment paste with organic or inorganic pigments under the pain of some surfactants to form a stable and uniform pigment paste with certain fluidity or thixotropy and strong coloring strength. Specially designed for factory painting coloring, good batch reproducibility, small color difference control, superior structural performance, strong coloring power, stable viscosity, no dry caking, not subject to microbial corrosion, no glycol, low VOC content, non-toxic, non-hazardous, environmentally friendly products.
When using water-based color paste, we should pay attention to:
1, although the water-based color paste can be good compatibility with a variety of coatings, but before use, or need to do the mixing test of color paste and paint, to determine the color paste and paint mixed with good capacity, and does not return to coarse, non-flocculation, before you can be color mixing.
2, before using the water-based color paste must be fully stirred evenly, to avoid uneven state of the color paste because the water-based color paste is not used for a long time or for some other reasons, thus affecting the accuracy of how much water-based color paste is added each time.
3, water-based color paste added to water dilution, need to stir at a uniform speed, in the process of adding paint when the operation can not be too fast, otherwise it is very easy to produce flocculation and other undesirable phenomena.
4, if you can not use up a barrel of color paste at once, you must immediately cover the lid to avoid the remaining water-based color paste is contaminated or because of the evaporation of water dry crack.
