Introduction:
Our 801-D rheological additive is a premium-grade, self-activating organic ammonium montmorillonite organoclay. Engineered for optimal performance in low-to-medium aliphatic hydrocarbons, esters, and ketones, it is ideal for enhancing the rheological properties of paints and printing oils, especially in high polar solvent systems. In mediums such as xylene and butyl acetate, 801-D disperses effortlessly without the need for additional activators. For low polar solvents like 200# solvent oil and mineral-based white oil, incorporating a polar activator (95% ethanol, 30-40% weight) is recommended for optimal dispersion. Comparable to Bentone-SD1, 801-D offers superior performance and versatility.
Application:
The 801-D additive is a versatile, broad-spectrum rheological enhancer suitable for various applications including antiseptic paints, printing oils, marine coatings, industrial decorative paints, automotive primer coats, and sealing materials.
Usage:
To achieve optimal dispersion and activation, 801-D should be added during the grinding phase of production. The additive activates fully under the cutting power of grinding or whipping. Here's a step-by-step guide:
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, white oil aliphatic hydrocarbons), include a polar activator (e.g., 95% ethanol) at 30-40% weight of 801-D and whip at high speed for 10-20 minutes. For medium-high polar solvents (xylene, xylene-butyl acetate), self-activation occurs without an activator.
4. Add wetting agent and pigment, then grind and disperse (whipping, ball-milling, sanding) to achieve the desired fineness.
5. Incorporate additional materials as required and continue to disperse until a homogeneous mixture is obtained.
Dosage
The appropriate dosage of 801-D in paint formulations is influenced by the desired thickening effect, rheological performance, and the degree of pigment stabilization required. Typically, the dosage ranges from 0.5-1.5% of the total paint volume. This can be adjusted based on previous organoclay formulations, with 801-D often requiring a lower percentage compared to traditional organoclays.
