Dispersant is a surfactant that has two opposite properties: lipophilicity and hydrophilicity within the molecule. It can evenly disperse solid and liquid particles of inorganic and organic pigments that are difficult to dissolve in liquids. , and can also prevent the settling and agglomeration of particles.
Dispersants can reduce viscosity, improve pigment dispersion efficiency, improve gloss, prevent floating and blooming, reduce flocculation, and increase storage stability.
Classification Application
Dispersants by chemical The composition can be mainly divided into carboxylate/polyacrylate (ionic), acrylic block polymer, phosphate, etc.
Dispersants are widely used in many industries, such as common coatings, adhesives, cosmetics, pesticides, textile fibers, etc.
A good dispersant product is mainly reflected in the following points:
1. Good dispersion performance, can prevent filler particles Aggregation between each other;
2. Appropriate compatibility with fillers;
3. Good thermal stability;
4. During molding and processing Good fluidity;
5. Non-toxic and does not affect the performance of the product.
Product recommendations
SN 5040
SN 5040 is an anionic surfactant with excellent wetting and dispersing properties. It has low foaming properties, can improve the fluidity of coatings, and has excellent performance in stabilizing slurry viscosity.
Suitable for coatings and water-soluble coatings for coated paper, as well as inorganic pigments and fillers such as clay, calcium carbonate, titanium dioxide/titanium dioxide, and talc.
Dispers760W
Dispers760W is a wetting and dispersing agent used in water-based printing ink and coating systems. It is especially suitable for carbon black and organic pigments. It has good viscosity reducing effect and can improve Tinting strength and gloss of carbon black and organic pigments.
BYK-9076
Wetting and dispersing agent BYK-9076 can effectively reduce floating color and blooming, improve fluidity, and has high color strength. and hiding power and longer storage stability.
Suitable for various pigments, especially recommended for stabilizing acidic and neutral carbon black pigments. It can be used in solvent-based and solvent-free coatings, adhesives and PVC plastisols. One important application is the preparation of Solvent-free pigment concentrate for the above applications.
BYK-110
BYK-110 is an ideal choice for acid catalytic systems due to its anionic properties. It can effectively reduce viscosity, improve fluidity and increase pigment addition. It can be used as a wetting and dispersing additive in solvent-based and solvent-free coatings and printing inks, and to stabilize inorganic pigments, especially titanium dioxide.
BYK-163
BYK-163 has broad compatibility, which can prevent multi-pigment systems from floating and blooming, and increase the Gloss, color intensity, clarity and hiding power of coatings while reducing abrasive viscosity. It can be used in various solvent-based formulations and can also be used for post-remediation of problematic paint.
BYK-190
BYK-190 can enhance the gloss of coatings, increase color intensity, and improve the transparency of transparent pigments and the hiding power of opaque pigments. At the same time, it can effectively reduce viscosity, improve fluidity, and increase pigment content. It is suitable for producing stable resin-free pigment shrinkage.
