Compatibility of GA 1900

GA 1900 is compatible with most common emulsions. Dilution with glycols, glycol ethers and alcohols is good.

 

Application

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℃.
