Introduction:
801-D rheological additive is a premium dispersible, self-activated organic ammonium montmorillonite organoclay. It is the ultimate rheological solution for low to medium aliphatic hydrocarbons, esters, ketones, and various high-polar solvent systems used in paints and printing oils. In medium to high-polar solvents such as xylene, butyl acetate, and cyclohexanone, it disperses effortlessly without an activator. For low-polar solvents like 200# solvent oil and white oil, a polar activator (95% ethanol, 30-40% of the organoclay weight) is necessary for optimal dispersion. Comparable to Bentone-SD1, this product sets a new standard in performance.
Application:
801-D is an exceptionally versatile, broad-spectrum rheological additive perfect for antiseptic paints, printing oils, boat paints, industrial decorative paints, automotive primer coats, and sealing materials.
Usage:
During the product manufacturing process, 801-D rheological additive should be directly added during grinding. Under the cutting force of grinding or whipping, it ensures complete dispersion and activation of the pigment. Follow these steps for optimal usage:
1. Add resin/solvent
2. Introduce 801-D additive and whip at high speed for 10-20 minutes
3. If using low-polar solvents like 200# solvent oil and white oil, incorporate a polar activator (e.g., 95% ethanol) at 30-40% of the organoclay weight and whip at high speed for 10-20 minutes. For medium to high-polar solvent systems such as xylene or xylene-butyl acetate, no activator is needed for self-activation.
4. Add wetting agent and pigment, then grind and disperse (whipping, ball-milling, sanding) until the required fineness is reached
5. Finally, introduce other materials from the ingredient list and continue to disperse until uniform.
Dosage
The dosage of 801-D rheological additive in paint formulations is influenced by the desired thickening effect, rheological control requirements, and the degree of pigment precipitation. The typical range is 0.5-1.5% of the total paint volume. Generally, it can be calibrated based on the amount of conventional organoclay used before optimization, often requiring less.
