Hydrophilic Pigment Paste Used for Water Based System Coloring
Hydrophilic pigment paste used for water based system coloring
From the definition, water based pigment paste is that can be used or water-based system coloring or coating. And whether means the hydrophilic of all water based pigment paste is very good?
Shanghai Caison Color is a professional water based pigment paste manufacturer. Our engineer can use simple method to judge the hydrophilic of water based pigment paste in Caison R&D Center.
Hydrophilic and hydrophobic properties of the materials are depends on the structure of the material itself. Some small molecules with polar groups, such as hydroxyl (-OH), carboxyl (-COOH), is similar polarity with water, so it has good compatibility with water. These auxiliaries which are used to prepare water based pigment paste by CAISON engineers, so the pigment paste formulation has very good hydrophilic, and finished water based pigment paste also has better hydrophilic. When it is used for textile pigment printing, textile fibers (especially cotton fibers) has good hydrophilic, so textile fibers also has good compatibility with these water based pigment paste in water based coloring system.
Studies show that water-based paste is not generalized,different hydrophilic values have important influence on coloring application of water based pigment paste.
When Shanghai Caison Color water-based pigment paste engineers are designing the pigment paste formulation for exterior paint coloring, they should fully consider the water repellency of exterior paints. During the auxiliaries of water based pigment paste formulation, adding substances with hydrophobic groups, such as hydrocarbon group; these special auxiliaries not only can help wet the pigment particles and good compatible with water, but also can lock in moisture before hydrophobic.
Water-based pigment paste is a seemingly simple but very complex applications coloring material, involving a very wide range applications. The users should select different kinds of water based pigment paste according to different application conditions. If the user does not know more about these points, he should keep good communication with our engineers, in order to ensure the customers choose suitable water based pigment paste.
Shanghai Caison Color has many kinds of water based pigment paste, the varieties of different colors and different kinds is more than 300, there is four distinctions:
1. Non-ionic water-based pigment paste, anionic water-based pigment paste, cationic water-based pigment paste;
2. Water-based pigment paste with resin, non-resin water-based pigment paste;
3. Hydrophilic water-based pigment paste, hydrophobic water-based pigment paste;
4. Transparent water-based pigment paste, water-based pigment paste with strong covering power;
