Naftoseal MC-216 Class B remains flexible and keeps a low bond strength on most metal substrates like aluminum, stainless steel, steel, titanium, composite, and many coatings under extremes of temperature, weathering, and stress.
The mixed compound is a thixotropic paste easily applied by extrusion, injection gun, spatula, or brush and it has excellent tooling properties.
The curing time may be reduced considerably by increasing the temperature (up to 60 °C / 140 °F max). The cured Naftoseal MC-216 B has low adhesion and forms a tough gasket, rubbery enough to mold itself to surface irregularities.
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.
