摘要:
A process for producing a repair coating on at least one metallic surface that is coated with at least one corrosion protecting coating A applied with at least one composition selected from the group of pretreatment compositions, of organic compositions and of silicon compound(s) containing compositions, whereby the at least one corrosion protecting coating A has been at least partially removed in the area Z, whereby a thin corrosion protecting coating B containing at least one silicon compound is applied with a solution or dispersion containing a silane, a silanol, a siloxane, or a polysiloxane on at least a part of the area Z. A further corrosion protecting coating C may be applied.
摘要:
A process for producing a repair coating on a metallic surface coated with a corrosion protecting coating A applied with a pretreatment composition, an organic composition or a silicon compound containing composition. Corrosion protecting coating A has been at least partially removed in the area Z, and a thin corrosion protecting coating B containing a silicon compound is applied with a solution or dispersion containing a silane, a silanol, a siloxane, a polysiloxane or a mixture thereof on at least a part of the area Z. A further corrosion protecting coating C which is generated with an organic composition like a primer, a wet-primer, an e-coat, a powder coat, a base-coat or a clear-coat or a composition which is the same or another siloxane composition as for the thin film B may also be applied to coating B.

摘要:
A process for the treatment or pretreatment of containers made of aluminum, aluminum-containing alloys, magnesium-containing alloys, iron-containing materials such as steel, coated iron-containing materials such as galvanized steel, or aluminum alloys, tinplate, brass or bronze, in particular the treatment or pretreatment of bags, tubs, bottles, cans, canisters, casks or tubes, wherein the process steps for the treatment or pretreatment take place at the same time as the application of the lubricant, with the agent used for the pretreatment or treatment, which also contains or is a lubricant, not essentially consisting of titanium or zirconium with fluoride and polymer, the lubricant possibly being formed first in the agent for the pretreatment or treatment or in the formation of the coating produced therefrom.

摘要:
A process for producing a repair coating on at least one metallic surface that is coated with at least one corrosion protecting coating A, applied from at least one composition selected from the group consisting of pretreatment compositions, organic compositions and silicon compound containing compositions; wherein the at least one corrosion protecting coating A has been at least partially removed in an area Z, and a thin corrosion protecting coating B, containing at least one silicon compound, is applied, from a composition that is a solution or dispersion containing at least one silane, silanol, siloxane, polysiloxane, or any mixture of these, on at least a part of the area Z. Optionally, a further corrosion protecting coating C may be applied on the thin corrosion protecting coating B whereby the at least one further corrosion protecting coating C is applied from at least one organic composition such as, for example, a primer, a wet-primer, an e-coat, a powder coat, a base-coat or a clear-coat, or with at least one composition which is the same composition as or a different composition than that which the thin corrosion protecting coating B is applied.
