CH-4    hyperdispersants

Properties:  

Appearance: amber waxy paste

Specific Gravity: 0.99 g/cm3£¨25¡æ£©

Acid Value: ¡Ü 30mgKOH/g

Hydroxyl Value: ¡Ü 50mgKOH/g

Decomposition  Temperature: ¡Ý 280 ¡æ

Package: 50KG Plastic Drum

Shelf Life: 2 years

Application Range:  

     For inorganic pigment, filler and azo toner surface treatment.

Usage:  

For inorganic pigment or filler surface treatment, heating 100phr CH-4  to  70¡æ , then  drop  it slowly into 900phr 40-42¡æ water to make 1000phr emulsion. Add the emulsion to the pigment before filtration or before other surface treatment. As for azo toner surface treatment, the emulsion may also be added before or during the coupling reaction.  

Dosage:  

     1-5% based on the dry weight of the pigment or the filler.  

Benefits :  

   Hydrophobic surface of the pigment to facilitate filtration.

   Less water in the press-cake, easy to dry.

   Finer particle size, looser aggregation, easy to disperse.

   Better heat-resistance of azo toner compared with their counterpart treated with rosin.

   Lower oil-absorption value, better tinctorial effect.
