The appropriate surface roughness profile has a dominant influence on the adhesion of paint and metallization coatings. There are several methods for assessing the roughness profile, quite often the clients of anti-corrosion works and even paint manufacturers require the assessment of the roughness profile by a specific method.
We offer the following methods for assessing the roughness profile of steel after shot-blasting:
- comparative method (COMPARATOR) according to ISO 8503-1 and 2
- replica tape method according to ISO 8503-5 or ASTM D 4417
- direct measurement method with electronic device according to ASTM D 4417
