LANTHANE™ TR-175 Passivate

A Unique, Highly Protective, Non-Chelated, Nano-Particle Trivalent Passivate for Zinc and Zinc Alloy Plated Surfaces

LANTHANE TR-175 Passivate is a unique and highly protective post-plating treatment system for zinc and zinc alloy deposits, except those deposited via mechanical methods. It is based on trivalent chrome compounds that are used in combination with nano-particle technology. LANTHANE TR-175 Passivate exhibits at least two unique operating features: (1) the film formed possesses self-healing characteristics which add measurably to the corrosion protection it provides; and (2) the operating solution can be easily waste treated because the operating bath does not contain compounds that chelate or complex metals.

LANTHANE TR-175 Passivate produces a uniform, bright, protective film on electro-deposited zinc surfaces. The color of the film varies slightly, depending upon the type of deposit over which it is applied. Alkaline non-cyanide zinc deposits typically exhibit a slight pearlescent appearance. Chloride zinc deposits generally exhibit a clear, white appearance. Zinc/iron deposits typically have a more pronounced iridescent appearance. In all these instances, the film formed can provide 240 to 350 hours of salt spray protection to the first appearance of white rust.

LANTHANE TR-175 Passivate polishes, brightens and passivates zinc surfaces via the same chemical reactions that take place in hexavalent chromates. Additionally, however, another chemical reaction takes place, directly at the surface of parts being treated, which deposits a very thin layer of highly protective nano-particles that affords the unique self-healing characteristics to the passivate film.

LANTHANE TR-175 A and LANTHANE TR-175 B are used to make-up a new bath. LANTHANE TR-175 R and LANTHANE TR-175 B are used to replenish an operating bath.

PRODUCT FEATURES

• Provides a film with uniform appearance that exhibits unique self-healing characteristics.
• The operating solution can be easily waste treated because it does not contain any chelating
  materials.
• Used at lower operating temperatures, and with shorter dwell times than competitive products that are formulated to provide high corrosion protection.
• Provides superior white rust corrosion resistance that surpasses results obtained from films formed by conventional hexavalent yellow chromates.
• Effective on a variety of different types of zinc and zinc alloy deposits.
• Easy to tailor to the unique operating characteristics of any given installation, or piece of operating equipment.
• With an appropriate topcoat, specific coefficient of friction and torque tension characteristics can be obtained.
• Operates with replenishment additives that can be added on a predictable schedule.
• Long operating life.
• Provides excellent paint adhesion.
