  • Process for producing a flowable, highly pigmented, low viscosity, hot-melt coating compound
    Patent number: 4175977
    Abstract: A process for preparing a flowable, nonaqueous, solvent-free highly-pigmented, low viscosity, thermoplastic, hot-melt coating compound, which comprises the steps of: (a) mixing in an initial stage from about 70% to about 95%, by weight, of pigment with from about 5% to about 30%, by weight, of low viscosity thermoplastic binder material for a period of time sufficient to obtain a homogeneous concentrate; and (b) mixing in one or more subsequent stages the homogeneous concentrate of step (a) with sufficient additional amounts of low viscosity thermoplastic binder material to yield a final homogeneous, flowable compound comprising from about 30% to about 70%, by weight, of pigment and from about 30% to about 70%, by weight, of low viscosity thermoplastic binder material.
