Features Of Solvay Rhodoline 675 Oil-Based Defoamer Surfactant

  1. Highly effective silicone-free defoaming in oil-based systems.

  2. Excellent compatibility with mineral oils, synthetic lubricants, and industrial greases.

  3. Low dosage efficiency — delivers rapid foam suppression and long-term foam control.

  4. Thermally stable up to 180 °C, suitable for high-temperature processing environments.

  5. Non-aqueous formulation ensures no risk of water-induced emulsification or phase separation.

Typical Applications Of Solvay Rhodoline 675 Oil-Based Defoamer Surfactant

  1. Metalworking fluids (neat oils and soluble oil concentrates).

  2. Industrial lubricants including hydraulic oils and gear oils.

  3. Coating and ink formulations based on solvent-borne or high-solids resin systems.

  4. Adhesives and sealants manufacturing where air entrapment compromises viscosity and film integrity.

  5. Textile auxiliaries such as spin finishes and softening emulsions.
