Introduction:
The 801-D rheological additive is an advanced, dispersible, self-activated organic ammonium montmorillonite organoclay. This innovative additive is specifically formulated for low to medium aliphatic hydrocarbons and high polar solvent systems, including esters, ketones, paint, and printing oils. In xylene and butyl acetate-based medium to high polar solvents, 801-D disperses effortlessly without the need for activators. However, in low polar solvents like 200# solvent oil and white oil, an activator (such as 95% ethanol, at 30-40% weight of the organoclay) is essential. This product is comparable to Bentone-SD1.
Application:
The 801-D rheological additive is a versatile, broad-spectrum solution. Perfect for use in antiseptic paint, printing oils, marine coatings, industrial decorative paints, automotive primer coats, and sealing materials.
Usage:
During the production process, the 801-D rheological additive is incorporated directly into the grinding stage. Under the cutting power of grinding or whipping to disperse the pigment, 801-D will fully activate and disperse. Typical usage steps include:
Add resin and solvent.
Introduce the 801-D additive and whip at high speed for 10-20 minutes.
For low polar solvents with 200# solvent oil and white oil, add a polar activator (such as 95% ethanol) at 30-40% weight of the organoclay, and whip at high speed for 10-20 minutes. In medium to high polar solvent systems with xylene or xylene-butyl acetate, no activator is needed for self-activation.
Incorporate wetting agent and pigment, then proceed with grinding and dispersing (whipping, ball-milling, sanding) to achieve the desired fineness.
Add remaining ingredients and continue to disperse until fully uniform.
Dosage
The dosage of 801-D rheological additive in paint formulations is governed by the desired thickening effect, rheology control, and degree of pigment precipitation. The typical range is 0.5-1.5% of the total paint amount. Generally, the dosage is determined through optimization trials and is often lower than that of common organoclays.
