Having both a hydrophobic and a hydrophilic group within its molecule, 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 cellulose |
|
4. |
Mechanical stability associated with polymer colloid
|
For these reasons, GOHSENOL is used as a polymerization emulsifier for vinyl acetate emulsion for wood and paper adhesives.
|
Generally, the emulsion prepared by using GOHSENOL as an emulsifier has the following features:
|
1. |
G Type (partially saponified PVA): Viscosity stability, high thixotropy, and high viscosity with the emulsion |
|
2. |
N Type (fully saponified PVA): Water resistance endowment to emulsion film; low thixotropy |
|
3. |
A Type (almost fully saponified PVA): Characteristics between those of the above two types (both water resistance and viscosity stability)
