ADHESION PROMOTER FOR SOLVENTBORNE CLEARCOAT MATERIALS |
摘要 |
The present invention relates to a solvent-borne clearcoat material comprising at least one additive preparable by reaction of at least one alpha,omega-hydroxy-functionalized oligoester which possesses an OH number of 30 to 160 mg KOH/g, a theoretical carbon-carbon double bond content of 1 to 2.5 mmol/g, a number-average molecular weight of 1000 to 3000 g/mol and a weight-average molecular weight of 2800 to 10 000 g/mol, and at least one alkoxysilane which possesses an OH-reactive functional group, the sum of the weight-percentage fractions of all additives of the invention being 0.5 to 10 wt%, based on the total amount of the solvent-borne clearcoat material. The present invention further relates to a method for producing multi-coat paint systems and to multi-coat paint systems producible with the aid of said method. The invention further relates to the use of the above additive in solvent-borne clearcoat materials for improving adhesion. |
