  801-D dispersible organic bentonite rheological additive

  Introduction:

  801-D rheological additive is a kind of dispersible, self-activated organic ammonium montmorillonite organoclay, is the rheological additive for the low-medium aliphatic hydrocarbon, ester and ketone, and paint, printing oil in some high polar solvent systems.In some medium-high polar solvent systems of xylene, xylene, ester (such as butyl acetate) and xylene, ketone (such as cyclohexanone) , it can be self-activatedly dispersed without activator; while it needs to add activator to help dispersion (95% ethanol, 30-40% weight of the organoclay as activator) in the low polar solvent with 200# solvent oil and white oil (mineral alcohol) aliphatic hydrocarbon. This product is similar to Bentone-SD1, Tixogel-MP100.

   

  Application:

  801-D is a kind of dispersible broad-spectrum rheological additive, which can be used in antiseptic paint, printing oil, boat paint, industrial decorative paint, car primer coat and sealing materials.

   

  Usage:

  801-D rheological additive is directly added during the grinding process of product-making, under the cutting power of grinding (or whipping) to disperse the pigment, 801-D will disperse and activate completely. The common usage is as follows:

  ●Add resin/solvent

  ●Add 801-D additive, whip in high speed for 10-20 minutes

  ●If solvent is the low polar solvent with 200# solvent oil and white oil aliphatic hydrocarbon, add polar activator (such as 95% ethanol), 30-40% weight of the organoclay, whip in high speed for 10-20 minutes; if solvent is the medium-high polar solvent system with xylene, xylene-butyl acetate, it can be self-activatedly dispersed without activator.

  ●Add wetting agent, pigment, grind and disperse (whipping, ball-milling, sanding) to the required fineness

  ●Add other materials in the ingredient, disperse continuously to be even.

   

  Dosage

  801-D rheological additive’s dosage in paint is determined by the required thickening effect, rheological performance controlling request, pigment’s precipitation degree, common dosage range is 0.5-1.5% of paint amount. Usually it can be probated according to the dosage of common organoclay before optimization. Usually, its dosage is less than that of common organoclay.
