Surface Profile

Showing all 3 results

The surface profile, or anchor pattern, of a blasted structure will directly affect a coatings performance.  Low profile may reduce coating bond strength (adhesion). Too high and the peaks may receive insufficient coverage and possibly rust prematurely. The costly application of more coating may be required if the profile is too high. For these reasons, surface profile should be measured prior to coating application to ensure that it meets contract specifications.

DeFelsko offers two types of devices for measuring peak to valley profile height in the forms of either a digital depth micrometers or a digital spring micrometers that make use of  replica tape (testex tape).
