M-NT 400 is a versatile process that is particularly suitable for the Pretreatment of aluminum suitable. It is frequently used in industrial production when a chromium(VI)-free conversion coating which provides corrosion protection and serves as a reliable adhesion promoter for coatings.

In addition to aluminum, M-NT 400 can also be used on other metals, including:

• Galvanized steel (e.g. hot-dip galvanized or electrolytically galvanized)
• Stainless steel
• Zinc die casting

The generated layer is in all cases Uniform, colorless and conductive - and therefore particularly suitable for applications in which both Technical functionality as well as optical neutrality are in demand.

In combination with Powder coatings or wet paints M-NT 400 ensures a significantly improved Liability and a Increased corrosion resistance. The process is also ideal for use with different types of material within a component, as it works on several types of metal and therefore minimizes the risk of damage. Reliable pre-treatment of complex assemblies makes it possible.

Due to its REACH and ROHS conformity M-NT 400 is a particularly future-proof choice - both for aluminum parts in the Automotive and aviation industry as well as for Galvanized components in mechanical engineering, electronics or building technology.

Passivation with M-NT 400, a chromium-free, liquid product for the conversion treatment of light metals, offers several advantages: it improves corrosion protection, serves as an ideal adhesion primer for paints and varnishes, and enables the formation of the natural oxide layer to be leveraged. 

The advantages in detail:

• Improved corrosion protection
• Excellent primer for paints and varnishes
• Levering of the natural oxide layer
• Environmentally friendly
• Versatile application

Overall, passivation with M-NT 400 provides improved corrosion resistance and an excellent basis for further coatings, while at the same time using an environmentally friendly process. 

Alodine and Bonderite are both brands of chromate conversion coatings used to protect metals from corrosion and to improve the adhesion of paints. The main difference lies in the manufacturing company and the composition. Alodine was formerly a Turco brand name and was later acquired by Henkel, while Bonderite is a Henkel brand that encompasses both Alodine technology and other related coating processes. 

Alodine (formerly Turco):

Alodine coatings are chromate conversion coatings that form a layer on metal surfaces that protects against corrosion and improves the adhesion of paints. Alodine coatings can be used on various metals such as steel, aluminum, zinc and other alloys. Alodine is known for its high corrosion resistance and good adhesion of paints and varnishes. 

Bonderite:

Bonderite coatings also provide corrosion protection and improve the adhesion of paints. Bonderite coatings are suitable for a wide range of applications, including aerospace, automotive and general industry. Bonderite is known for its reliability and durability.
