Solvirodia Rhodoline DF Defoamer
Product Description
The Solvirodia Rhodoline DF Defoamer series offers tailored foam control solutions for waterborne coatings, inks, and industrial formulations, combining silicone-free and silicone-enhanced technologies to address diverse application demands. Engineered with mineral oil or polysiloxane matrices, these defoamers destabilize macrofoam at interfaces while disrupting microfoam stability within coatings, ensuring rapid bubble collapse during high-shear processes like pigment grinding and substrate application
Compatible with acrylic, polyurethane, and hybrid resin systems, the series minimizes surface defects such as craters or pinholes without compromising gloss or adhesion. Variants optimized for acidic or alkaline environments maintain efficacy across pH 2–12, supporting stability in surfactant-rich formulations and long-term storage.

Application
1.Waterborne Coatings – Prevents foam-related defects (pinholes, craters) in architectural and industrial coatings, including latex-based systems
2.Adhesives & Sealants – Critical for foam control in pressure-sensitive adhesives (PSA) and water-based adhesives, ensuring bond strength and processing efficiency
3.Emulsion Polymerization – Optimizes acrylic, styrene, and vinyl acetate emulsion processes by stabilizing foam during reactions
4.Industrial Processes – Used in textile dyeing, pulp/paper production, and chemical manufacturing to maintain operational efficiency
