COATING COMPOSITION FOR ACHIEVING EXCELLENT MVSS ADHESION |
摘要 |
<p>A coating composition comprises a crosslinkable carbamate-functional resin and an aminoplast. The aminoplast comprises the reaction product of an aldehyde and a melamine. The aminoplast has a content of imino groups of less than or equal to about 10%, a content of alkylol groups of at least about 7%, and a remainder of groups being alkoxyalkyl groups, all based on a total number of reactive sites present in the melamine prior to reaction. A coating system includes a clear coat layer that comprises the reaction product of the crosslinkable carbamate-functional resin and the aminoplast. Threshold adhesion strength, in accordance with MVSS standards, can be achieved between glass and the coating system when the crosslinkable carbamate-functional resin and the specific aminoplast set forth above are reacted to form the clear coat layer, while minimizing problems associated with high viscosity of aminoplasts having a high content of imino groups of greater than 10%.</p> |
