What is an ANCHOR PATTERN, and how do I get it? We hear that question a lot, and maybe this will help answer those questions.
The anchor pattern or profile is extremely important to protective
coatings in that it provides for excellent coating adhesion. Coatings
manufacturers specify the optimal profile needed to achieve maximum
coating adhesion for each different coating.
Typically anchor pattern is expressed in mils, microns or millimeter
Pressure, distance from the surface and angle can effect the anchor
pattern but following are some general guidelines on how to achieve
specific anchor patterns. Assumption is 90PSI nozzle pressure,
2 feet from surface:
|Abrasive sizes vary and a tolerance of 10% should be maintained to expect these results, especially where abrasives are reclaimed and re-used. Reclaimed abrasives should be angular, not rounded and free from oil, grease, iron oxide, etc.|
