DePHOS™ EP 136 is an alcohol ethoxylate-based phosphate ester in free acid form. DePHOS™ EP 136 is an effective emulsifier and dispersant in aqueous formulations, and exhibits wetting, antistatic, and corrosion inhibiting properties. It may assist in the prevention of aluminium staining in metalworking fluid emulsions. DePHOS™ EP 136 is particularly effective when used to produce small particle size dispersions of resins for coating applications. DePHOS™ EP 136 can also be used as a surfactant in emulsion polymerization. Please submit a document request or general inquiry form if you’d like to access an SDS in another language.
