Introduction:
Introducing the 801-D Rheological Additive, a versatile, self-activating organic ammonium montmorillonite organoclay designed to enhance the performance of low to medium aliphatic hydrocarbons, esters, ketones, and various high-polar solvent systems like paint and printing oils. This additive excels in medium to high-polar solvent systems, including xylene and butyl acetate, where it disperses effortlessly without the need for an activator. However, in low-polar solvents with 200# solvent oil and white oil, it requires a polar activator (95% ethanol, 30-40% weight of the organoclay) for effective dispersion. Comparable to Bentone-SD1, 801-D is your go-to solution for superior rheological performance.
Application:
801-D is a highly dispersible, broad-spectrum rheological additive, ideal for use in antiseptic paints, printing oils, boat paints, industrial decorative paints, car primer coats, and sealing materials.
Usage:
The 801-D rheological additive is best incorporated during the grinding phase of production. Under the shear forces of grinding or whipping, 801-D activates and disperses fully. Follow these steps for optimal results:
1. Add resin/solvent
2. Introduce 801-D additive and whip at high speed for 10-20 minutes
3. For low-polar solvents (200# solvent oil and white oil aliphatic hydrocarbon), add a polar activator (e.g., 95% ethanol) at 30-40% weight of the organoclay and whip at high speed for 10-20 minutes. In medium-high polar solvent systems like xylene or xylene-butyl acetate, the additive can self-activate without an activator.
4. Add wetting agent and pigment, then grind and disperse (whipping, ball-milling, sanding) to achieve the required fineness
5. Incorporate other ingredients and continue to disperse until uniform.
Dosage
The recommended dosage of 801-D rheological additive in paint formulations is influenced by desired thickening effects, rheological control needs, and pigment sedimentation levels. Typically, this ranges from 0.5-1.5% of the total paint volume. Usually, the dosage is less than that of conventional organoclays, making it an efficient choice for your formulation needs.
