Rhodoline DF 642M Defoamer

Rhodoline DF642M is a defoamer from Solvay's Rhodoline DF series, tailored for waterborne coatings, inks, adhesives, and related fields. It combines efficient foam control with eco-friendly properties, making it a versatile choice for aqueous systems.

Features Of Rhodoline DF 642M Defoamer

  1. Efficient Foam Management: Rapidly eliminates existing foam and provides long-lasting inhibition of new foam formation.

  2. Eco-Friendly: Zero VOC and free of APE (alkylphenol ethoxylates), meeting strict environmental standards.

  3. Strong Compatibility: Stabilizes and disperses well in various coating and emulsion systems without affecting product performance.

  4. Easy Handling: Low viscosity allows for simple addition and mixing, suitable for industrial production processes.

Typical Applications Of Rhodoline DF 642M Defoamer

  1. Emulsion Polymerization: Ideal for systems like NBR (nitrile butadiene rubber), SBR (styrene-butadiene rubber), styrene, and acrylics, controlling foam to enhance product quality.

  2. Waterborne Coatings and Inks: Prevents foam-related defects (bubbles, cracking, peeling) in waterborne architectural coatings, latex systems, and inks.

  3. Adhesives: Suitable for manufacturing pressure-sensitive adhesives (PSA) and other adhesives, ensuring stable production processes.
