Rhodoline DF 642NI Defoamer

Rhodoline DF 642NI is a specialized defoamer from Solvay's Rhodoline DF series, engineered to deliver effective foam control for industrial applications. Its mineral oil-based formulation, enhanced with silica, makes it a robust solution for diverse aqueous systems.

Features Of Rhodoline  DF 642NI Defoamer

  1. Mineral Oil-Based with Silica: Incorporates silica to boost defoaming efficiency, particularly in challenging foam-prone systems, ensuring reliable performance.

  2. High-Efficiency Foam Control: Rapidly breaks down existing foam and provides long-lasting inhibition, maintaining stability in industrial processes.

  3. Good Compatibility: Disperses well in various aqueous systems, integrating smoothly into coatings, adhesives, and other industrial formulations without compromising product properties.

Typical Applications Of Rhodoline  DF 642NI Defoamer

  1. Waterborne Coatings: Reduces foam during production and application of waterborne paints, architectural coatings, and latex-based products, preventing surface defects like pinholes or uneven finishes.

  2. Adhesives and Sealants: Ideal for adhesive manufacturing (including pressure-sensitive adhesives/PSA), where precise foam control is critical to ensure product quality and processing efficiency.

  3. Industrial Processes: Used in emulsion polymerization and other industrial operations where foam can disrupt workflows or compromise end-product performance.
