Introduction to the use of water-based color paste!
I. Introduction of water-based color paste

Water-based color paste refers to organic or inorganic pigments in the surfactant wetting, dispersing effect (can also be added to water-soluble resins), the formation of uniform, stable, with a certain degree of mobility or thixotropic mobility, strong coloring strength of the concentrated pigment paste. There are two kinds of water-based color paste system: one is high pigment content without resin system; the other is low pigment content with 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, generally does not cause floating color and bloom, reasonable choice of additives, generality. The latter pigment concentration is relatively low, but with good coloring power, good color development, mobility and viscosity is more stable, the system contains resin, compatibility needs to do the test, otherwise it is easy to lead to the paint floating color bloom.

Second, the main technical indicators of color paste

1, the quality of color powder in color paste (mainly depends on its international pigment number)

International pigment number: It is simply understood as the pigment code formulated uniformly according to the different molecular structure of the color powder, which determines the light-resistant performance (weathering performance) and chemical-resistant performance (acid-resistant and alkaline-resistant performance) of the color paste, and also determines the general color phase of the color paste, and due to the production process of each color paste company is not the same, the color phase of the color paste may have a subtle difference.
