Dextrol OC 4025 Phosphate Ester Surfacant

For emulsion Polymerization and Waterborne Architectural Coatings

Dextrol OC 4025 surfactant is the neutralized (ammonium salt) form of an ethoxylated tridecyl alcohol phosphate ester. In emulsion polymeriation, Dextrol OC 4025 is an effective emulsifier that provides efficient particle size control, low coagulum and improved handing and storage stability.

Dextrol OC 4025 surfactant is the most hydrophobic neutralized product in the Dextrol line and is effective in the production of all common latex types including vinyl, vinyl acrylic, vinyl acetate ethylene (VAE), acrylic and styrene acrylic.

Dextrol OC 4025 surfactant can also improve gloss and enhance pigment dispersion and color acceptance in watewrborne latex paints. Dextrol OC 4025 does not contain any alkyl phenol ethoxylates (APEOs).
