Binder mixture and a high scratch resistance is produced which the coating agent contains, as well as from this and weathering resistance as well as coating with good optical properties

摘要

The present invention, 1.0 wt%, nitrogen-containing silane groups and cross-linking at least phosphorus for non-volatile components of the mixture and binder (A) at least one hydroxyl group-containing compound - at least one catalyst (D) it contains relates to a binder mixture, a hydroxyl group containing compound (A), (here, the hydroxyl functional group of the at least one average of the polyester, which is a hydroxy-functional polyester of one or at least one C at least _{8 ~C} 9 _- formulas) are esterified with monocarboxylic acid (I) [wherein, R ₁ is an aromatic or aliphatic hydrocarbons acyclic aliphatic C atoms of at least 3, same as R ₃ R ₂ is a hydrocarbon of the aromatic or aliphatic acyclic aliphatic or different and / or R _1, the same as the R ₂ R ₃ acyclic fat or different or R ₁ and / or hydrogen and is characterized in that the blocked, at least one tertiary amine] is a hydrocarbon aromatic or aliphatic group, and contains at least one catalyst (D). Multistage coating methods in use under the coating agent, as well as the object of the present invention, this as a clear coat for the production of multi-layer coating of chromogenic or and effect-imparting and coatings are based on this binder mixture further regarding the use of this coating process for the automotive refinishing paint and automotive paint production or use of a coating agent.
