Elcometer 125 Surface Comparator
Surface Profile
The proper and effective preparation of a surface prior to coating is essential. Making
sure that the correct roughness – or profile – has been generated is essential.
If the profile is too low, the adhesion of the coating to the surface will be reduced. Too
high and there is the danger that the profile peaks will remain uncoated – allowing rust
spots to occur.
