This installation for application of a coating product comprises a print head equipped with a plurality of nozzles each controlled by a valve supplied by a product source. A product accumulator, installed on a product circulation circuit, comprises a deformable or movable wall delimiting, at least in part, a first chamber of variable volume supplied with coating product and a second variable-volume chamber supplied with gas, under a predetermined pressure equal to a nominal operating pressure of the print head. The first chamber of variable volume is supplied or purged with coating product due to a difference between an instantaneous coating product ejection rate from the print head and a supply rate to the print head from the source. A control unit adjusts an operation setpoint value of the source as a function of the difference between instantaneous ejection flow rate and supply flow rate, to reduce this difference.

A method includes introducing a first material component having a first permittivity and a second material component having a second permittivity to a mixing unit. The first and second material components are advanced through the mixing unit at a mixing ratio to form a material component mixture that is dispensed from the mixing unit. A third permittivity of the material component mixture, which is related to the first permittivity, the second permittivity, and the mixing ratio, is determined. The third permittivity is compared to a predetermined permittivity, which is related to the first permittivity, the second permittivity, and a predetermined mixing ratio. If the third permittivity differs from the predetermined permittivity by a threshold limit or more than the threshold limit, a corrective response is generated.
