SafeGardCC-3400 SafeGard CC-3400Seal#2

SafeGard CC-Seal#2 is a reactive aluminum conversion coating that can be used to give you a long-term clear shine on aluminum. Due to the reactive bond with the aluminum, this coating will not wash off at the car wash, in high humidity or by the ocean. 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.

SafeGard 4100 - Dry in place aluminum surface treatment to prevent aluminum corrosion and discoloration under humid conditions. SafeGard CC-4100 is not affected by heat so it is often used in areas that reach high heat such as 400-500°F. Used to prevent corrosion on in process aluminum parts, and as a surface treatment before painting aluminum.

Additional Chrome-Free Pre-Treatments for Aluminum:

SafeGard CC-5000 is a chromate-free inorganic seal for anodizing and aluminum oxide coatings. SafeGard CC-5000 is a direct replacement for standard dichromate seal used in military applications specification MIL-A8625C. It contains no organics or toxic environmentally unfriendly inorganic. Will not breakdown with heat above 160°F as will dichromate seals, almost identical color to final product and is used at almost the same temperature and time as a chromate seal. This is not an iron phosphate coating.

SafeGard CC - Seal#10 - Enhances paint and coating adhesion specifically from filiform corrosion on aluminum castings such as (380, 383, 360, aluminum zinc die castings). This product is to be used with either the SafeGard CC-3000 or the SafeGard CC-3400. Seal#10 is an environmentally safe, clear seal which is applied at room temperature.
