Introduction:
The 801-D Rheological Additive is an advanced, dispersible, self-activated organic ammonium montmorillonite organoclay. This premier additive is engineered for exceptional rheology control in low to medium aliphatic hydrocarbons, esters, ketones, and paints. In high-polarity solvent systems like xylene and butyl acetate, the 801-D disperses effortlessly without an activator. For low polarity solvents, including 200# solvent oil and mineral alcohol, an activator (e.g., 95% ethanol at 30-40% weight) is required for optimal dispersion. Comparable to Bentone-SD1, the 801-D offers unparalleled versatility and efficiency.
Application:
The 801-D Rheological Additive is a versatile, dispersible solution ideal for antiseptic paints, printing inks, marine coatings, industrial decorative finishes, automotive primers, and sealants. Its broad-spectrum capabilities ensure superior performance across diverse applications.
Usage:
For optimal performance, integrate the 801-D Rheological Additive during the grinding phase. The additive's cutting-edge design ensures complete dispersion and activation under the mechanical stress of grinding or whipping. The typical usage procedure is as follows:
1. Add resin/solvent.
2. Incorporate the 801-D additive and whip at high speed for 10-20 minutes.
3. For low-polarity solvents, add a polar activator (e.g., 95% ethanol at 30-40% weight) and whip for 10-20 minutes. For medium-high polarity solvents like xylene and butyl acetate, the additive self-activates without an activator.
4. Add wetting agent and pigment, then grind and disperse (via whipping, ball-milling, or sanding) to the desired fineness.
5. Introduce other formulation materials, ensuring continuous and even dispersion.
Dosage
The dosage of the 801-D Rheological Additive in paint formulations is determined by the desired thickening effect and rheological control. Typically, the dosage ranges from 0.5-1.5% of the paint volume. Adjustments can be made based on the specific formulation requirements, generally using less than traditional organoclays.
