Bresle Patches Standard High Adhesion

The Bresle Test will measure water-soluble salts and corrosion products on blast-cleaned steel. Those compounds are almost colorless and are localized at the lowest point of the rust pits. If they aren't removed prior to painting, chemical reactions can result in blister formation and accumulations of rust that destroy the adhesion between the substrate and the applied protective coating.

The Bresle Patches are latex and chloride free
They have an elastomer that the syringe does not pierce and comply with ISO 8502-6 and 8502-9.
The elastomer on the Bresle Patch is not latex or polyurethane. It is a specific material manufactured for the Bresle Patch. We do not use latex due to latex being chloride containing material and polyurethane is not a strong enough material to stop the syringe piercing the elastomer when carrying out the injection-sucking cycles as per ISO 8502-9 section 6.
When high adhesion strength Patches are required for testing on very corroded or coarse-grade blasted steel, use the Bresle Patches Plus as an alternative to the Standard Bresle Patches.
