Paint Inspection Gage IV (plastic)

Paint Inspection Gage IV (plastic)

Principle : A special cutting tool which is integral with the gage is used to incise a small, precision V-groove through the paint film and info the substrate. This V-groove is observed vertically with an illuminated microscope bearing a measuring reticle (scale).

Direct measurement of total coating thickness, and thickness of individual coats of paint is a unique capability of the "Toque Gage". Thus, in addition to routine use, it often serves as a "referee" instruments to calibrate indirect or "non-desctructive" thickness measuring instruments. Other uses include assessment of substrate conditions and coating adhesion, and observation of microscopic cracking, tendency for brittleness, blistering, cratering, or other microscopic film symptoms.

The Tooke Gage has been used to assess sandblast cleaning work, to measure plating and paint thickness on ceramics, metal, wood, and concrete, and even to measure protective backing thickness on mirrors. It is virtually the only tool for measuring paint on plastics. As indicated above, the quality of the incision in the film discloses much about characteristics of brittleness and adhesion of the material.
