Abstract

The present invention concerns a reagent coating mass which can be used in slot-die-coating of flat support materials in the manufacturing processes of test strips. Advantageously, the reagent mass of the invention exhibits certain superior rheological properties such as viscosity, surface tension and thixotropy. The reagent mass is preferably used to coat thin, narrow and homogeneous stripes of reagent material onto flat web material.
