ASTRA WA® - ASTRA CHEMICAL

WETTING AGENTS

ASTRA’S wetting additives result in a fine and homogeneous distribution of solid particles in liquid media and ensure the long-term stability of such systems. The additives stabilize pigments (inorganic, organic and also effect pigments) and fillers. The liquid phase can comprise water and the entire range of organic solvents of varying polarity.

Wetting agents are surface-active substances and improve the wetting of solids. Dispersing agents prevent particles flocculating by various mechanisms (electrostatic effects, steric effects). Wetting and dispersing additives unite both mechanisms of action in one product, i.e. they are both wetting and stabilizing.

ASTRA WA SERIES

Key Features

•Superior Pigment and Filler Stabilization: Whether dealing with inorganic, organic, or effect pigments, our additives provide reliable stabilization, ensuring a consistent and high-quality output.

•Enhanced Wetting and Dispersion: Combines wetting and dispersing capabilities, reducing particle flocculation and promoting better coverage and color development.

•Versatile Solvent Compatibility: Effective in water and a broad spectrum of organic solvents, making them adaptable to numerous applications and formulations.

Benefits OF USING ASTRA's WETTINGS AGENTS

•Improved Process Efficiency: Reduced formulation time and enhanced processing capabilities.

•Consistent Quality: Achieve repeatable, high-quality results in your final products.

•Versatility: Suitable for a wide range of applications and compatible with various liquid systems.

HOW IT WORKS

1. Wetting Mechanism: Our additives lower the surface tension between the liquid and solid particles, enabling the liquid to spread more effectively over the particles, promoting better wetting.

2. Dispersing Mechanism: By utilizing electrostatic and steric effects, these agents prevent particles from coming together and forming clumps. This ensures a stable dispersion, maintaining the fine distribution of particles over time.

Applications:

Coatings and Paints: Achieve vibrant colors and smooth finishes with stabilized pigments and fillers.

•Printing Inks: Enhance print quality with even dispersion and reduced clogging.

•Adhesives and Sealants: Ensure uniform performance and consistency in complex formulations.

•Plastic and Polymer Systems: Maintain the integrity and appearance of composite materials with stable dispersions.
