water-based wetting and dispersing agent in resin-free color paste better color development BYK2012

GENERAL DESCRIPTION

Anjeka-6871 is a high-performance wetting and dispersing additive designed for aqueous coatings and printing inks. It effectively stabilizes a broad spectrum of pigments, including inorganic pigments, organic pigments, and carbon blacks. It significantly reduces grinding paste viscosity, improves storage stability, and is suitable for both resin-containing systems (emulsions, water-soluble resins) and resin-free pigment concentrates.

PRODUCT DATA

Chemical Composition: Structured polymer with pigment-affinic groups.

Typical Physical & Chemical Data: (The following data are typical values and are not to be treated as binding specifications.)

APPLICATION GUIDELINES

Features and Benefits
Anjeka-6871 offers excellent compatibility with common aqueous resin systems, making it the preferred choice for dispersing pigments in resin-containing pastes. Its robust stabilization extends to a wide range of pigments, including transparent and opaque organics, as well as carbon blacks. It is also highly effective in resin-free aqueous pigment concentrates.

Key Advantages:

Broad Formulation Compatibility: Its dispersing efficacy remains unaffected by the presence of organic amines, rheology modifiers, wetting agents, or co-solvents in the grind.

Superior Processability: Significantly reduces grinding paste viscosity and eliminates thixotropy, enabling easier handling and processing.

Enhanced Final Properties: Provides strong deflocculation, leading to excellent color development, transparency, and color strength—ideal for high-performance printing inks and coatings.
