摘要：
A method for simultaneously coating multiple thin layers of relatively viscous fluids comprises the relative adjustment of the viscosity of the fluids in order to achieve a viscosity ratio in the optimum range without adversely affecting the adhesive properties of the fluids. In the preferrred method, viscosity is adjusted by varying the temperature of one or both fluids prior to coating and/or by reformulating the liquids to vary their relative viscosities.
