polymeric wetting dispersant superior color development for carbon black in polyester syestems EFKA 4063

GENERAL DESCRIPTION

A wetting and dispersing agent designed for solvent-based automotive coatings, industrial coatings, and concentrated pigment dispersions. Particularly well-suited for stabilizing ultrafine carbon black and organic pigments, it significantly reduces the viscosity of grinding media and effectively enhances color development performance.

PRODUCT DATA

Chemical Composition: Solution of graft copolymer with pigment-affine groups

The data provided on this sheet represents typical values and not product specifications.

STORAGE and TRANSPORT

Storage at temperatures below 15℃ may result in layering or crystallization; heat to 40℃ and thoroughly mix. Storage beyond 12 months is not recommended.

SPECIAL NOTES

Surface treatments of certain organic pigments may adversely affect the effectiveness of this wetting and dispersing agent. In such cases, consider using untreated pigments of the same type.

APPLICATION GUIDELINES

Key Features and Benefits:

Utilizing steric hindrance, the additive aids in the facilitation of pigment deflocculation, ensuring stability. ANJEKA—6173 induces a uniform charge among pigment particles, creating repulsion and steric hindrance mechanisms that efficiently ward off possible flocculation. This results in an improved gloss, heightened color intensity, increased transparency, and enhanced coverage of the coating, concurrently reducing the viscosity associated with the grinding process.

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

PROCESSING INSTRUCTIONS

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