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:
- Excellent protective colloid ability for vinyl acetate monomer
- Resilience of dried membrane
- 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:
- G Type (partially saponified PVOH): Viscosity stability, high thixotropy, and high viscosity
- N Type (fully saponified PVOH): Water resistance (emulsion film) and low thixotropy
- 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).
