The degree of profile on the surface affects a coating’s overall performance and determines aspects such as adhesion, coverage and overall volume of coatings used. If the profile is too large the amount of coating required increases, otherwise there is a danger that the peaks remain uncoated - allowing rust spots to occur. If the profile is too small there may be an insufficient key for adequate adhesion.
Elcometer offer a comprehensive range of surface profile gauges and surface comparators that are designed to quickly and accurately measure the profile a variety of materials.
