Rhodoline DF691 is a mineral oil-based, silicone-free defoamer from Solvay (Rhodia, France), specifically formulated for aqueous systems. It is positioned to deliver rapid foam knockdown, long-lasting inhibition, and stability in challenging pH conditions, making it a reliable choice for diverse industrial applications.
Mineral oil-based formulation enhanced with nonionic surfactants, balancing efficiency and compatibility.
Silicone-free, minimizing the risk of surface defects like craters—critical for coating applications where finish quality is key.
APEO-free and VOC-free, aligning with sustainable and eco-friendly standards to support green manufacturing practices.
Emulsion paints and coatings (preventing surface defects)
Adhesive manufacturing (ensuring process efficiency)
Agricultural sprays (maintaining application consistency)
Wastewater treatment (managing foam in industrial effluents)
