In the manufacture of couché paint, the pH of the dispersed pigments must be in the neutral-alkaline range before the introduction of the binder in question. We do not recommend the use of film agents in the composition of couché paint, because the Fortcryl 7670 already has a T.M.F.F. (minimum film formation temperature) low enough. Fortcryl 7670 gives the couché ink excellent pseudoplastic rheology in such a way that the application is greatly facilitated even at high machine speeds.
