Introduction:
Our 801-D rheological additive is a highly efficient, dispersible, and self-activated organic ammonium montmorillonite organoclay designed for enhanced performance in low to medium aliphatic hydrocarbons, esters, and ketones. It excels in paint, printing inks, and high-polar solvent systems. In mediums such as xylene, xylene-esters like butyl acetate, and certain ketones like cyclohexanone, it self-activates without an additional activator. However, for low-polar solvents like 200# solvent oil and white oil, it requires a polar activator (95% ethanol at 30-40% weight of the organoclay). This product shares similarities with Bentone-SD1.
Application:
Our versatile 801-D rheological additive is ideal for a wide range of applications, including antiseptic paints, printing inks, boat paints, industrial decorative paints, automotive primer coats, and sealing materials.
Usage:
For best results, add the 801-D rheological additive during the grinding stage of production. Under high shear forces, it will fully disperse and activate, ensuring optimal pigment dispersion. Follow these steps for effective usage:
1. Add resin/solvent
2. Introduce 801-D additive and whip at high speed for 10-20 minutes
3. For low-polar solvents like 200# solvent oil and white oil, add a polar activator (e.g., 95% ethanol) at 30-40% of the organoclay weight and whip at high speed for 10-20 minutes. For medium-high polar solvents like xylene or xylene-butyl acetate, the additive will self-activate without an activator.
4. Add wetting agent and pigment, then grind and disperse using methods such as whipping, ball-milling, or sanding to achieve the desired fineness.
5. Introduce additional ingredients and continue dispersing until the mixture is homogeneous.
Dosage
The optimal dosage of 801-D rheological additive in paint formulations is typically 0.5-1.5% of the total paint volume. This dosage is determined by the desired thickening effect, rheological control, and pigment stability. Generally, the required amount is less than that of standard organoclays, and can be adjusted based on previous formulations.
