From the preparation of the surface to be coated, through climatic condition monitoring to the dry film thickness evaluation, visual assessment and gauge-based testing will ensure adequate process control.
For steel surface preparation, the removal of rust and other contamination and the creation of a surface profile is required to enhance the adhesion of the applied coatings. Elcometer offer a range of visual standards for rust removal and a simple test for dust on blast-cleaned surfaces. In order to determine the level of soluble salt contamination of the blast cleaned surface, a range of salt contamination methods are available including the Bresle Patch Method, the Saturated Filter Paper method and the chloride-specific titration tube method.
For climatic condition monitoring Elcometer offer simple bi-metallic magnetic thermometers and electronic thermometers for temperature measurement, with wet and dry bulb hygrometers and electronic dewpoint meters for the measurement and data-logging of relative humidity and dewpoint temperatures. Oven temperature logging and wind velocity measurement are also available.
For coating thickness Elcometer offer wet film combs, mechanical and electronic non-destructive dry film thickness gauges, the destructive paint inspection gauge and the non-contact powder coating thickness gauge.
For post coating assessment of adhesion and porosity of the coating there is a full range of adhesion testers and low and high voltage holiday detectors.
