Introduction:
The 801-D rheological additive represents a breakthrough in dispersible, self-activating organic ammonium montmorillonite organoclay technology. Tailored for low to medium aliphatic hydrocarbons, esters, and ketones, this additive excels in high polar solvent systems including xylene and butyl acetate. It effortlessly self-activates without the need for additional activators in many cases, although low polar systems with 200# solvent oil and white oil will require an activator like 95% ethanol to optimize dispersion. Comparable to Bentone-SD1, 801-D stands out for its versatility and superior performance.
Application:
The 801-D rheological additive is a versatile, broad-spectrum solution ideal for antiseptic paints, printing oils, boat paints, industrial decorative paints, automotive primers, and sealing materials. Its wide-ranging utility makes it an indispensable component in various formulations.
Usage:
Incorporating the 801-D rheological additive is straightforward during the grinding process. Under the cutting power of grinding or whipping, 801-D disperses and activates fully. Follow these steps for optimal use:
1. Add resin/solvent
2. Introduce the 801-D additive and whip at high speed for 10-20 minutes
3. For low polar solvents with 200# solvent oil and white oil, add a polar activator (e.g., 95% ethanol) at 30-40% of the organoclay's weight. Whip at high speed for 10-20 minutes. In medium-high polar solvents like xylene and xylene-butyl acetate, the additive self-activates without an activator.
4. Add a wetting agent and pigment, then grind and disperse (whipping, ball-milling, sanding) until the desired fineness is achieved.
5. Incorporate other materials in the ingredient mix, dispersing continuously until homogeneous.
Dosage
The optimal dosage of 801-D rheological additive in paint formulations depends on the desired thickening effect, rheological performance requirements, and pigment precipitation. Generally, a dosage range of 0.5-1.5% of the total paint volume is recommended. This range is often lower than that required by common organoclays, allowing for efficient and effective performance.
