The Bresle Patches will allow you to extract salts from blast-cleaned steel for measurement using the Horiba Conductivity Meter in the Bresle Patch Test.

Salts are almost colourless and are localized at the lowest point of the rust pits.  If they are not 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.

Supplied in packs of 35.

Compliant to ISO 8502-6.
