Product Description:

The 801-D₂ is a kind of self-dispersing organic Bentonite which can be dispersed without need of any polarity activator and the high-shear conditions. It is applicable to the medium to high polarity solvent system of the ketone, ester, glycol, aether and aether-ester, alcohol, etc. Its superior suspension capability will greatly simplify the recipe and the producing procedure. It may revise the technical process after simplification and substitute the gas phase silicon dioxide, through which the cost will be effectively reduced. This model of product is equivalent to Bentone SD-2.

Usage:

The 801-D₂ can be easily dispersed and thus can be fed into the solvent at any phase during the preparation. Adopt the high shear method for the dispersion while the low-shear for the paint mixing, without need of any polarity activator or pre-gel. The specific amount required depends on the viscosity reinforcement, anti-flowing & dropping and the pigment anti-depositing status. The typical dosage of the 801-D₂ is calculated to 0.1-1.5% in terms of weight percent.

Applications:

Industrial top paint, auto lacquer, Nano organic composite material
