Product Information

It has outstanding resistance to aviation gasoline and jet fuel, as well as resistance to the chemicals and petroleum products used in the aircraft industry.

Naftoseal MC-630 Class A maintains its flexibility and bond strength on most metal substrates like aluminium, stainless steel, steel, titanium, composite and many coatings under extremes of temperature, weathering and stress. The mixed compound is a pourable, slightly thixotropic paste easily applied by extrusion, injection gun, spatula and 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).

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. PUR and EP topcoats as well as composite components should be pre-treated by the Naftoseal MC-110 Adhesion Promoter.
