CH-17    hyperdispersants

Properties:  
Color:pale yellow

Appearance: powder solid 

Melting Point: 182-204℃ 

Specific Gravity:1.05-1.07g/cm3(25℃)
Active proportion:100% 

Decomposition Temperature:≥260℃ 

Package:50KG Plastic Drum

Shelf Life: 2 years

Application Range and Benefits:  

AFor water-based phthalocyanine pigment surface-treatment, improve the dispersability, color strength and mobility of the pigment.

BFor inorganic pigment (ferric oxide) and filler surface-treatment, improve the dispersability and tinctorial effect, increase the hiding power of the pigment.

 dosage:  

AFor water-based phthalocyanine pigment surface-treatment, the dosage is 2-8% based on the dry weight of the pigment.

BFor inorganic pigment (ferric oxide) and filler surface-treatment, the dosage is 0.5-1.5% based on the dry weight of the pigment

Usage

AFor water-based phthalocyanine pigment surface-treatment, add CH-17 before acid cleaning and filtration, keep stirring for more than 2 hours.

BFor inorganic pigment (ferric oxide) and filler surface-treatment, add CH-17 before acid cleaning, keep stirring for more than 2 hours. The dried pigment mixed with oily aids (CH-1DCH-2CCH-3ACH-3B, etc.)to make oily pigment; or mixed with water-based aids (CH-10 for example) to make water-based pigment. 

Remarks:

    CH-17A are CH-17B is easy to dissolve in water, the stirring time can be shortened; CH-17C can dissolve slightly in the water, dissolving it with alkalic liquid or ethanol before it is added into the pigment, and keep stirring longer to guarantee better surface-treating effect.
