Emulsion Stabilizer Applications

Having both hydrophobic and hydrophilic groups within its molecules, GOHSENOL™ performs excellently as an emulsifier for synthetic resin emulsions. In particular, it has the following advantages over other surfactants on the market:

  • 1.Excellent protective colloid ability for vinyl acetate monomer
  • 2.Resilience of dried membrane
  • 3.Reliable adhesion to hydrophilic materials such as cellulose

Therefore, GOHSENOL™ is preferred as a polymerization emulsifier for vinyl acetate emulsions used for bonding wood and paper.

Generally, the emulsion prepared by using GOHSENOL™ as an emulsifier has the following features:

  • 1.G Type (partially saponified PVOH): Viscosity stability, high thixotropy, and high viscosity
  • 2.N Type (fully saponified PVOH): Water resistance (emulsion film) and low thixotropy
  • 3.A Type (almost fully saponified PVOH): Characteristics between those of the above two types (both water resistance and viscosity stability)
