Document Type and Number:
Japanese Patent JP2001514692
Kind Code:
A
Abstract:
A process for producing scratch-resistant coatings, especially scratch-resistant multicoat finishes, involving use of coating compositions which after curing have a storage modulus E' in the rubber-elastic range of at least 107.5 Pa and a loss factor tan delta at 20° C. of at least 0.05, the storage modulus E' and the loss factor having been measured by dynamic mechanical thermoanalysis on free films having a film thickness of 40±10 mum, and comprise as binders one or more polyacrylate resins having a hydroxyl number of from 100 to 240, an acid number of from 0 to 35, and a number-average molecular weight of from 1500 to 10,000, and as crosslinkers one or more free or blocked isocyanates and/or triazine-based components which crosslink with the hydroxyl groups of the binder to form ether and/or ester structures.
