Introduction:
Our groundbreaking 801-D rheological additive stands as a dispersible, self-activating organic ammonium montmorillonite organoclay. Ideal for low to medium aliphatic hydrocarbons, esters, ketones, and paints, it excels in high-polar solvent systems. In mediums like xylene, butyl acetate, and cyclohexanone, it disperses effortlessly without an activator. For low polar solvents combined with 200# solvent oil and white oil, simply blend with a polar activator (95% ethanol, 30-40% of organoclay weight) for optimal dispersion. This product mirrors the exceptional qualities of Bentone-SD1.
Application:
The 801-D is a versatile, broad-spectrum rheological marvel, perfect for antiseptic paints, printing oils, marine coatings, industrial decorative paints, automotive primers, and sealing materials.
Usage:
For the best results, introduce 801-D during the grinding phase of production. Under the intense cutting forces of grinding or whipping, the additive will fully disperse and activate. Follow these steps for optimal effectiveness:
1. Add resin/solvent
2. Incorporate 801-D additive, whip at high speed for 10-20 minutes
3. For low polar solvents with 200# solvent oil and white oil, add a polar activator (95% ethanol, 30-40% organoclay weight), whip for 10-20 minutes. For medium-high polar solvents like xylene or xylene-butyl acetate, no activator is needed for self-activation.
4. Add wetting agent and pigment, grind and disperse (using whipping, ball-milling, or sanding) until the desired fineness is achieved.
5. Add remaining ingredients into the mixture and continue to disperse until even.
Dosage
The proper dosage of 801-D in paint is contingent on the desired thickening effect, rheological performance, and pigment precipitation. Typically, the range is 0.5-1.5% of the total paint volume. The dosage can be calculated based on common organoclay practices, though 801-D generally requires a lesser amount for optimal performance.
