Principle of dispersant HT-5 168

Polymer dispersant HT-5 168 is used in various organic pigments, such as azo, copper phthalocyanine, heterocyclic ring, lake and inorganic pigment carbon black. , and has excellent dispersion stability, so that the particles are stably distributed in dozens of nanometer scales, which can significantly increase the coloring power of products. Used in pigment printing paste, water-based ink, water-based paint and other dispersion systems, the long-term dispersion stability of the system is significantly improved, and its performance is better than that of Japanese Joncryl68.

● Method of use

Firstly, the polymer dispersant HT-5 168 was prepared into a solution with appropriate concentration, and then the pigment was added for grinding. Generally, the concentration of dispersed pigment is 30%-40% of the total weight of slurry, and the dosage of dispersant is 5%- 15% of the weight of pigment. After grinding for several hours, the particle size and particle size distribution of the dispersion were determined. After meeting the requirements, it can be used as pigment printing paste or compounded with base material to form water-based coatings and water-based inks. Still operate according to the current method of the enterprise.
