Thermoplastic coating and binding agent for medicinal forms

Abstract

A thermoplastic coating and binding agent containing a non-homogeneous mixture of, based on the total weight of A and B: A) 5-95 wt % of a thermoplastic acrylic plastic with a melting temperature above room temperature, but below 200° C., a glass transition temperature below 120° C., and a melt viscosity of 1,000 to 1,000,000 Pa·sec at the melting temperature; and B) 95-5 wt. % of a flow improver, which, at room temperature, is not compatible with the thermoplastic acrylic plastic, has a melting temperature above room temperature but below 200° C., a molecular weight under 20,000 d, and a melt viscosity below 100 Pa·sec at the melting temperature of the acrylic plastic.
