Pigment grinding vehicle for water based ink
Coating materials for water based OPV
Solution Preparation and Properties
The following formulations are offered as starting points of making resin solutions. The resin should be cut under agitation by high-speed mixers. Although GA 1900 will dissolve at room temperature, the solution process can be greatly accelerated by use of warm water up to 70℃.
GA 1900 | 30.0 | 30.0 |
D. Water | 62.5 | 62.3 |
Ammonia Water (28%) | 7.5 | － |
Monoethanol amine | － | 7.7 |
pH | 8.5 | 8.8 |
Viscosity, cps (25℃, Brookfield) | 3,500 | 4,000 |
Recommendation
Adding Soluwet-200, 1~2% into the pigment base, the viscosity stability as time can be improved and the fluidity can be better GA-1900 couldn’t be recommended for the emulsion
Safety Information
