Applications & Uses

  • Lanspec EMP404 is a highly ethoxylated nonionic surfactant system that is APE free.
  • Typically Lanspec EMP404 can be used in Emulsion Polymerisation systems as a performance replacement to Nonyl Phenol Ethoxylates with an EO range between 30-50.
  • Lanspec EMP404 is recommended to be used in conjunction with an anionic such as: Kemsurf ESD60, Kemsurf ESD, Kemsurf EM9 and Kemsurf OS38.

Lanspec EMP404 is an excellent emulsifier for emulsion polymerization for systems such as:

  • Vinyl Acetate - Homopolymer
  • Vinyl Acetate - Acrylic
  • Styrene - Acrylic
  • Acrylic Monomers - Esters and Acids
