is a RoHS compliant chromate free seal aluminum, zinc and magnesium. This final seal will help you achieve maximum corrosion resistance and paint adhesion on corrosion susceptible alloys such as 2024 aluminum and 380-cast aluminum. For shop/field repairs, you will get the same performance with our cold applied SafeGard CC-7000 when used in combination with the SafeGard CC-3400seal#2. The combination of SafeGard CC-7000 and SafeGard CC-3400Seal#2 has been tested at Boeing in St. Louis to meet the salt spray performance, the paint adhesion and electrical conductivity to meet the performance requirements of Mil-C-5541.
