Application of the Bonded Film

There are several thickness measuring devices which can be used for more accurate measurement. Disapio used an automatic bench micrometer with indicator readings to 0.5 /ym. Hopkins and Campbell used a dial indicator or a four- 

The following procedure will usually give a uniform, adherent film of the required thickness, and the operator should be prepared to experiment in order to achieve a satisfactory performance. 

The nozzle should be held at a distance from the component such that the spray reaches the surface wet, but dries quickly. 

The spray density should be tested by placing a sheet of paper beside the component. The paper should be uniformly darkened in a single pass. 

The gun should be continually swirled to keep the constituents dispersed.
