Contains some free alcohol ethoxylate and nonionic surfactant which gives a very good wetting property. Can be neutralised with a number of bases, which gives flexibility regarding solubility in different solvents. When using NH3 as neutralising base, the solubility and colour acceptance will be good in both water borne and solvent borne paints.
