Rheology-Controlled Inks: Organophilic Bentonite Clay for Consistent Print Performance

Organophilic Bentonite Clay for Consistent Print : Organoclay bentonite, colloidal rate (≥95%), particle size distribution (D50 20-40μm) and temperature resistance. We all know that the particle size and distribution, directly affects his ability to prevent settlement, in the paint industry, we make the particle size is relatively fine, so that the role of anti-settling can be realized. In ink printing, we pay special attention to the distribution test of particle size.

Temperature resistance, generally we are controlled at minus 20 ℃ to 180 ℃, this is our organic bentonite application range of a temperature control of a data test, high-temperature type grease application is generally at 180 ℃ for 72 hours to achieve stability, then we belong to the high-temperature stabilized organobentonite. Colloid rate, that is, it will be left to stand for 48 hours after the settlement volume did not change, which is why we have to measure his colloid rate.

In the paint industry we recommend that the viscosity of organoclay bentonite range from 8000 to 12,000, while the grease we require more than 12,000. This is based on different shear forces.
