Introduction:
The 801-D rheological additive is an advanced, dispersible, self-activated organic ammonium montmorillonite organoclay. It is specifically formulated as a rheological additive for various solvent systems including low to medium aliphatic hydrocarbons, esters, and ketones. It excels in high polar solvent systems used in paint and printing inks. Remarkably, in medium to high polar solvents such as xylene and butyl acetate, it disperses effortlessly without needing an activator. However, in low polar solvents like 200# solvent oil and white oil (mineral alcohol) aliphatic hydrocarbons, an activator is required (such as 95% ethanol at 30-40% of the organoclay's weight) for optimal dispersion. This product parallels the performance of Bentone-SD1, ensuring superior stability and functionality.
Application:
The 801-D additive is a versatile rheological agent ideal for a wide range of industrial applications. It is perfect for use in antiseptic paints, printing oils, marine coatings, industrial decorative paints, automotive primers, and sealing materials. Its broad-spectrum capabilities make it a valuable addition to any formulation requiring enhanced viscosity and stability.
Usage:
The 801-D rheological additive should be incorporated directly during the grinding phase of production. Under the mechanical force of grinding or whipping, the pigment and 801-D will fully disperse and activate. Follow these general steps for optimal use:
1. Add resin/solvent.
2. Introduce the 801-D additive and whip at high speed for 10-20 minutes.
3. If using low polar solvents like 200# solvent oil and white oil aliphatic hydrocarbons, add a polar activator (e.g., 95% ethanol) at 30-40% of the organoclay's weight and whip at high speed for 10-20 minutes. For medium-high polar solvents like xylene or xylene-butyl acetate, the additive disperses autonomously without an activator.
4. Add wetting agents and pigments, then grind and disperse using methods such as whipping, ball-milling, or sanding to achieve the desired fineness.
5. Incorporate additional materials as required, ensuring continuous dispersion until homogeneous.
Dosage
The amount of 801-D rheological additive required in paint formulations is contingent on the desired thickening effect, rheological properties, and pigment settling characteristics. Typically, the dosage ranges from 0.5% to 1.5% of the total paint volume. It is advisable to experiment with the common organoclay dosage initially and adjust accordingly, generally requiring a lesser amount than traditional organoclays.
