How to choose a good water-based colorant?
1. The particle fineness in water-based color paste is an intuitive indicator that reflects the coloring power dispersion effect and storage stability of the color paste. Customers should look at the important indicator of color strength when choosing a good water-based color paste, which is to use the same white base material. Add the amount of color paste to meet the standards required by the customer. The less the amount added, the better.
2. The compatibility of color paste and the system used is an important criterion to determine whether it is suitable. First of all, water-based color paste is suitable for water-based systems. Customers must do a compatibility test before using it for the first time.
3. The varieties of water-based colorants represent different pigment structures, which mean that in addition to different colors, they also have different resistance to chemical media, mainly acid resistance and alkali resistance, that is, chemical migration resistance, temperature resistance, and weather resistance. They should be selected when choosing. Fully understand the ingredients of water-based color paste pigments.
4. The storage stability of water-based color paste is also an aspect that determines the quality of water-based color paste. Usually water-based color paste has a shelf life of 1-2 years.
