Process Line Coating Thickness

Process lines typically apply thin coatings onto metalized substrates. This includes clear and lightly pigmented thin organic laquer coatings and adhesive coatings. It also includes wax on aluminum or steel, plus thin water-based coatings. 

NDC's infrared gauges are designed to measure the thickness of clear and lightly pigmented coatings on shiny or reflective surfaces using coat weight. These coatings may be just a few mils or microns thick. NDC's infrared gauges are designed to directly measure the thickness of these coatings to an accuracy of 0.1 micron. 

NDC's NIR gauges measure the thickness of these coatings using coat weight without the need for muli-scanner configurations and subtractive measurements. This greatly simplifies the installation, maintenance and measurement accuracy. The IG710S gauge is designed to measure organic and water-based coatings, whist the SR710S gauge is used for clear and lightly pigmented organic laquer and wax coatings on aluminum and steel substrates. 

 

Summary of benefits:
