- Surface Preparation
To obtain good adhesion, clean surfaces with appropriate cleaners (e.g. Chemetall's Ardrox® products like Ardrox® 5529 or Ardrox® 5575) to remove dirt, grease and processing oils just prior to sealant application. Use lint-free rags or paper towels that are free of oil. Always pour cleaner on the cloth to avoid contamination of the cleaner supply. Clean one small area at a time, quickly wiping it dry before the cleaner's solvent evaporates to prevent redeposition of oil, wax or other contaminants. Usually, in the case of most epoxy resin primers, surfaces need not be additionally prepared with an adhesion promoter to improve adhesion. PUR and EP topcoats as well as composite components should be pre-treated by the Naftoseal® MC110 Adhesion Promoter.
