Chromate-free and metal phosphate free treatments and compositions for applying a conversion or passivation coating for metals, more particularly, steel, zinc coated steel, and aluminum surfaces. The methods of the invention comprise contacting the requisite metal surface with a treatment composition comprising a member or members comprising one or more Group IV B elements, fluoride, and phosphonic acid or phosphonate. Optionally, a silane may be added as a treatment component.

Rinsable metal pretreatment methods and compositions

The present invention relates to a composition for the treatment of metal substrates including an aqueous solution of a Group IVA metal ion, selected from the group consisting of zirconium, titanium, hafnium and mixtures thereof, and a water-soluble or water-dispersible polyphenolamine.

Polyphenolamine composition and method of use

Tri-cation zinc phosphate conversion coating compositions are disclosed. The compositions include a phosphate component, ions of nickel, manganese, and zinc, and a glycerophosphate component, such as disodium glycerophosphate. Coatings formed from these compositions provide improved corrosion resistance to metal substrates and provide a uniform layer for the application of paint finishes. Processes of making and using these compositions are also disclosed.

Methods for providing a conversion coating to a metal surface are provided. The methods comprise applying to a metal surface an aqueous composition comprising a diglycidyl ether of Bisphenol A, a fluoacid, and a silicon compound containing a hydrolyzable group.

Method for forming chromium-free conversion coating

A cleaning and passivating treatment for metals comprising an amphoteric surfactant which is a caprylic acid derivative of imidazoline compounds. The treatment is substantially free of amines, alkanolamines and phosphates. The preferred treatment includes small quantities of borate ions and molybdate ions. In addition a nonionic surfactant may be added as a foam control agent.

Cleaning and passivating treatment for metals

An acid based cleaning and passivating treatment for metal surfaces is provided. The single step acid based cleaning and passivating is provided by incorporating a corrosion inhibiting amount of an ethoxylated tertiary dodecyl mercaptan into an acidic metal cleaner.

Method of cleaning and passivating a metal surface with acidic system

Compositions and methods for cleaning and etching an aluminum surface with a low etch, low phosphate alkaline cleaner solution are disclosed. The preferred composition employs a stable combination of an alkali metal hydroxide, gluconic acid, a detergent source, an aluminum sequestrant, an oil emulsifier, a defoamer, and a hydrotrope.

Low phosphorous, low etch cleaner and method

An emulsion cleaner formulation is provided which is free of toxic or hazardous materials listed under SARA 313. The emulsion cleaner formulation employs a blend of triethanolamine soap of tall oil fatty acid, polyethylene glycol (400) dioleate and polyethylene glycol (400) monooleate as a stabilizing agent. The emulsion cleaner may also include a nonionic surfactant. The emulsion cleaner also includes both oil soluble and water soluble rust inhibitors.

Metal working emulsion cleaner

A method and composition for reducing and maintaining the coefficient of friction of a metal surface cleaned by an alkaline cleaner, while preventing the formation of foam on said surface, is disclosed. The cleaned metal surface is contacted with a treatment comprising monoethanolamine, an ethoxylated alkyl ether phosphate and a silicate.

Metal surface treatments

A black, no-rinse conversion coating on metal surfaces is provided. The treatment of a metal such as aluminum or aluminum alloys with a composition of hexavalent chromium, an acrylic/itaconic modified styrene butyl acrylate polymer resin, a fluoacid, and carbon black results in a black no-rinse conversion coating.
