Solvay RHODOLINE® 581B Surfactant
Categories: Fluid

Material Notes: Description: Mineral oil defoamers for high PVC systems

Chemical Name: DEFOAMER

CAS: 64742-47-8

Available in: Asia Pacific, Europe, Latin America and North America

Solubility(2% in DI Water): Coarse Dispersion, RP-0547

Applications: The amount of RHODOLINE© 581B required for a specific application should be determined in each case, because of the variance in factors creating foam. Since severe foaming is often controlled with 0.1% RHODOLINE© 581B, this concentration is suggested as a starting point. Make subsequent adjustments to dilute or increase the concentration to the most efficient and economical strength. In some applications, higher concentrations will be needed to obtain the desired persistence. RHODOLINE© 581B will separate on prolonged standing; therefore, it should be mixed well before using. For greater efficiency and stability, an emulsion pre-mix is suggested. This is prepared by adding with mixing one part of water to two parts of RHODOLINE© 581B. More dilute emulsions may be used; however, they require more frequent mixing before use.
