Title:
着色された水性基層および溶剤型上層の二重層硬化機構により形成される低温硬化コーティング
Document Type and Number:
Japanese Patent JP6999643
Kind Code:
B2
Abstract:
Shelf-stable low temperature cure coating compositions that include a hydroxy-functional resin, a crosslinking agent, and a catalyst that does not catalyze the crosslinking reaction between hydroxy-functional resin and the crosslinking agent contained therein, but instead between a hydroxy-functional resin and a crosslinking agent contained in a different low temperature cure coating composition. In addition, low temperature cure composite coatings that include: a waterborne basecoat containing a first hydroxy-functional resin, a first crosslinking agent, a first catalyst, and an organic solvent; and a solventborne topcoat containing a second hydroxy-functional resin, a second crosslinking agent, a second catalyst, and water, where the first catalyst migrates into the topcoat from the basecoat and catalyzes the reaction between the second hydroxy-functional resin and crosslinking agent, and the second catalyst migrates into the basecoat from the topcoat and catalyzes the reaction between the first hydroxy-functional resin and crosslinking agent.
