I just know that people put the resin into the water based metal complex dyes after long time. What can it use? We can use one word disperse. People who are in the dyes industry know what is disperse. The purpose of adding resin is to stabilize the dispersion effect. In that case, the dye molecules slowly formed the Newton fluid under the inclusion of the resin.
We are not going to explain more here about Newton fluid, but not like water based metal complex dyes.The dispersion of the water system is mainly depended on the high dielectric constant of water to maintain the stability of the dispersion. This is the principle that the aqueous dispersion produces, has the high strength the ionization ability.
They will compete with the dispersing agent on the surface of the pigment. Water resin molecular weight is not as structured as the dispersant. Will be combined with pigment particles, and the formation of winding and flocculation. Most of the thickening agent can be regarded as water soluble resin. Alkali swelling type thickener. They "absorb" a lot of water, but they are squeezed by the pigment dispersion, resulting in flocculation. Even non - ionic resins or thickening agents, such as cellulose, are also not helpful.
Sometimes we have to consciously add water to get a shear force to promote the dispersion. Adding some pigments will be able to achieve this effect. At the same time, it also improves the efficiency. Unless the machine is generally fine color, without the addition of resin. Even if the machine is in fine grinding color, later joined.
Just resin can make the water based metal complex dyes has such a big change, visible dye exists everywhere in this delicate place. We have to make every detail good for producing great quality metal complex dyes.
