| 摘要 |
Described is a method for producing a multicoat color and/or effect paint system, the method comprising: (1) applying a pigmented aqueous basecoat material to a substrate, (2) forming a polymer film from the basecoat material applied in stage (1), (3) applying a clearcoat material to the resulting polymer film, and subsequently (4) curing the polymer film together with the clearcoat film. In stage (1) a pigmented aqueous basecoat material is used that comprises at least one ether compound of the structural formula (I);;wherein R1 is a Cx alkyl radical, R2 is a Cy alkylene radical and R3 is a Cz alkyl radical, n is 0 to 5, and wherein x+n·y+z=18 to 24. Also described are coating materials and also the use of the ether compounds in pigmented aqueous coating materials. |
