Product Information

Naftoseal MC-630 Class A is a two-component, manganese-dioxide cured polysulfide polymer system providing excellent fuselage seals. 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 aluminum, 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. It has excellent tooling properties.

Naftoseal MC-630 Class A Techkits can be mixed by MCI-Mixer or by appropriate 2- component mixing and dosing systems. The curing time may be reduced considerably by increasing the temperature (up to 60C / 140F max).

Applications:Sealing fuselages

Specifications Approvals:

  • AIMS 04-05-001, DAN 1159

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 pourcleaner 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 ofoil, wax or other contaminants. PUR and EP topcoats as well as composite componentsshould be pre-treated by the Naftoseal MC-110 Adhesion Promoter.
