SANDBLASTING ROUGHNESS SURFACE COMPARATORS

Sandblasting roughness surface comparators – SA6204SAB1-SA6204SAB2

A correct preparation of the surface before performing coating process is essential, in order to ensure a correct anchorage and proper degree of protection given by the coating itself. It is therefore necessary to check if roughness or profile fall within certain predetermined parameters. The values below or above these parameters could lead in the first case to a poor adhesion, and in the second to potential presence of special (peaks) exposed or poorly protected.
Optical sandblasting roughness surface comparators – spherical “Shot” and angular “Grit” include a series of standard sandblasted surface comparators, useful for comparison and identification of roughness surface values by visual and tactile method.
Note: Surface comparators can not be certified.
