Introduction:
801-D rheological additive is a premium dispersible, self-activated organic ammonium montmorillonite organoclay. Designed for superior rheology adjustment, it excels in low-medium aliphatic hydrocarbons, esters, ketones, as well as in paint and printing oil within high polar solvent systems. When used in medium-high polar solvents like xylene, butyl acetate, and cyclohexanone, 801-D effortlessly self-activates without needing an additional activator. However, in low polar solvents such as 200# solvent oil and white oil, an activator (95% ethanol at 30-40% weight of the organoclay) is necessary for dispersion. Comparable to Bentone-SD1, this additive offers unmatched efficiency and performance.
Application:
801-D is a versatile, dispersible rheological additive ideal for use in antiseptic paints, printing oils, boat paints, industrial decorative paints, car primer coats, and sealing materials.
Usage:
For optimal performance, 801-D rheological additive should be added during the grinding phase of product formulation. Under the mechanical force of grinding or whipping, 801-D will fully disperse and activate. The typical usage procedure includes:
1. Add resin/solvent
2. Introduce 801-D additive and whip at high speed for 10-20 minutes
3. In low polar solvents like 200# solvent oil and white oil, add a polar activator (e.g., 95% ethanol) at 30-40% of the organoclay's weight, then whip at high speed for 10-20 minutes. In medium-high polar solvent systems like xylene and butyl acetate, 801-D can self-activate without an activator.
4. Add wetting agent and pigment, then grind and disperse (using whipping, ball-milling, or sanding) until the desired fineness is achieved.
5. Incorporate other materials into the mixture, ensuring continuous and even dispersion.
Dosage
The dosage of 801-D rheological additive in paint is contingent on the desired thickening effect, rheological performance requirements, and the degree of pigment precipitation. Typically, the dosage ranges from 0.5-1.5% of the total paint amount. It can be trialed based on common organoclay usage, and usually, the required dosage is lower than that of standard organoclay.
