Introduction:
801-D rheological additive is a high-performance, self-activated organic ammonium montmorillonite organoclay. Designed for low-medium aliphatic hydrocarbons, esters, and ketones, it excels in paint and printing oil applications within high-polar solvent systems. In solvent systems like xylene and butyl acetate, it disperses effortlessly without an activator. For low-polar solvents such as 200# solvent oil and white oil, an activator (95% ethanol at 30-40% weight of the organoclay) is required for optimal dispersion. Comparable to Bentone-SD1, this product ensures superior rheology.
Application:
801-D is a versatile rheological additive suitable for antiseptic paints, printing oils, boat paints, industrial decorative paints, car primers, and sealing materials.
Usage:
Incorporate 801-D rheological additive directly during the grinding phase. Under the intense cutting force of grinding or whipping, it fully disperses and activates. Follow these steps for optimal use:
Add resin/solvent
Introduce 801-D additive and whip at high speed for 10-20 minutes
For low-polar solvents like 200# solvent oil and white oil, add a polar activator (95% ethanol) at 30-40% weight of the organoclay and whip at high speed for 10-20 minutes. In medium-high polar solvent systems such as xylene-butyl acetate, it disperses without an activator.
Add wetting agent and pigment, then grind and disperse using whipping, ball-milling, or sanding until the desired fineness is achieved.
Incorporate other ingredients, ensuring continuous and uniform dispersion.
Dosage
Determine the dosage of 801-D based on the desired thickening effect, rheological control, and pigment precipitation. Typically, use 0.5-1.5% of the paint volume. Often, the required amount is less than that of standard organoclays, allowing for efficient optimization.
