Clemtex Anchor Pattern Standards

1/2 Mil The CAPS (Clemtex Anchor Pattern Standards) are designed for the purpose of a quick field inspection of a blast cleaned surface to determine the anchor pattern depth within 1/2 mils.

The anchor pattern is all-important to protective coatings in that it provides excellent coating adhesion. It is important that the anchor pattern be uniform over its entire surface. This is accomplished using a clean, well-graded or sized abrasive.

The chart included will aid in obtaining the proper abrasive size specified.

It should be remembered that abrasive sizes vary and a close inspection of size tolerance (approx. 10%) should be maintained, especially where abrasives are reclaimed and re-used. Reclaimed abrasives should be angular and not rounded and free from oil, grease, iron oxide, etc.

NOTE: 100 psig should be used for those not already stated.
