ABSTRACT:
The viscosity of thixotropic dispersions of polyvinyl flouride in latent solvents is controlled by adding volatile alcohols or acids to decrease viscosity, stirring the dispersion to eliminate gas bubbles, and then adding volatile amines to increase viscosity on curing the amine and the alcohol or acid evaporate together to keep viscosity in desirable ranges.
