Title:
二重層硬化機構で極性－促進の層間触媒移動により形成される低温硬化コーティング
Document Type and Number:
Japanese Patent JP7333776
Kind Code:
B2
Abstract:
A double coating, curing method, cured coating, and kit are provided. A first layer of the double coating can be a first cure coating composition, which has a first hydroxy-functional resin, a first crosslinking agent, and a non-polar catalyst. A second layer of a second cure coating composition can have a second hydroxy-functional resin, a second crosslinking agent, and a polar catalyst. The non-polar catalyst catalyzes crosslinking between the second hydroxy-functional resin and crosslinking agent, and not between the first hydroxy-functional resin and crosslinking agent. The polar catalyst catalyzes crosslinking between the first hydroxy-functional resin and crosslinking agent, and not between the second hydroxy-functional resin and crosslinking agent. The polarity of the catalysts can facilitate catalyst migration from one layer to the other. The separate compositions can be shelf-stable and/or the curing can occur at low temperature.
