Emulsion Polymerization with GOHSENX™ AND GOHSENOL™

Having both hydrophobic and hydrophilic groups within its molecules, GOHSENX™ and 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, GOHSENX™ and 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)

GOHSENX™ Z, especially Z-210 is suitable for one component water resistant vinyl acetate emulsion. (Emulsion satisfied JAS Category I or II and D3 of DIN EN204/EN205).
