The difference between waterborne dyes and polypropylene

The difference between waterborne dyes and polypropylene

Answer:

Come back to answer your question: the dye is water-soluble, is the dye-based pigment. Polypropylene pigment is a polymer pigment that blends paint compounds with acrylic monomers. Of course there is a traditional gouache pigment, this is still a pigment, not a dye!
Polypropylene itself is not a pigment, it is not a dye. But there are a class of polypropylene pigment, is the acrylic, methacrylate, acrylic, methacrylic acid, and thickeners, fillers, and pigment particles mixed with the paint from the paint. The polymerization of the propylene-based monomer, after drawing the pattern, the occurrence of polymer polymerization, the pigment blockade in the polymer macromolecules, with water resistance characteristics, can be relatively long for a long time does not change color.
While the other is called a pigment, is water-insoluble, or oil-soluble. Its macromolecular structure is not hydrophilic groups, can not be dissolved in water. This pigment, that is, we paint the paint, paint the wall paint, paint the main pigment pigment.
We usually use organic pigment has two categories, one is the so-called water-based dye, in fact, is the dye. Its macromolecular structure contains sulfonic acid groups, carboxylic acid groups of these two hydrophilic groups, it is water-soluble, dissolved in water was a transparent solution. This type of dye is mainly used to dye textiles and paper.
