Organic Wetting Carbon Black Dispersing Agent Additive For Paints And Coatings

Product Overview

ANJEKA-6050 is a wetting and dispersing agent designed for solvent-based industrial coatings, wood coatings, and concentrated pigment dispersions. It is particularly suitable for stabilizing carbon black and organic pigments, especially in two-component polyurethane and baking systems, significantly reducing the viscosity of grinding materials.

Product Information

Chemical Composition: Co-polymer solution with pigment-affinitive groups.

Storage and Transport

Storage at temperatures below 0℃ may cause separation or cloudiness; heating to 20℃ and thorough mixing is recommended. Storage time is not advised to exceed 12 months.

Special Notes

Surface treatment of certain organic pigments may adversely affect the efficacy of this wetting and dispersing agent. In such cases, experimenting with untreated pigments of the same type is recommended. For coil coatings, consider the interaction between this cationic additive and acid catalysts. Free acids or epoxy-sealed acids are more suitable than amine-sealed acids.

Application Guidelines

Industrial Coatings

Features and Advantages:

This additive utilizes steric hindrance to disperse pigments and maintain stability. ANJEKA-6050 imparts the same charge to pigment particles, creating repulsion and steric hindrance, effectively preventing potential co-aggregation. This ensures that multi-pigment systems do not exhibit color floating or flocculation. Additionally, it enhances the gloss, color intensity, transparency, and hiding power of coatings while reducing grinding viscosity.

Recommended Levels

Additive levels (as purchased) based on pigments:

Titanium Dioxide: 1%—5%

Inorganic Pigments: 5%—15%

Organic Pigments: 30%—80%

Carbon Black: 70%—140%

The above data represents empirical levels; optimal levels should be determined through a series of experiments.

Incorporation and Processing Instructions

For optimal performance, add the additive to the grinding medium before introducing pigments. Pre-mix the resin and solvent components of the grinding medium, then slowly add the additive while stirring continuously. Do not add pigments until the additive is uniformly mixed.
