Title:
METHOD OF APPLYING SOLVENT-BORNE COATING COMPOSITION TO SUBSTRATE BY UTILIZING HIGH TRANSFER EFFICIENCY APPLICATOR TO FORM COATING LAYER THEREON
Document Type and Number:
Japanese Patent JP2022162553
Kind Code:
A
Abstract:
To provide a method for forming a coating layer on a substrate by a high transfer efficiency applicator while minimizing sag of a composition.SOLUTION: A method includes a step of applying a coating composition to a substrate through a high transfer efficiency applicator to form a coating layer on the substrate, where loss of volatiles is less than about 0.5 mass, and where the coating composition comprises: A. resin comprising an acrylic, a polyester, or combinations thereof; B. a melamine cross-linker; C. an optional pigment; D. an organic solvent; and E. at least one polyurea crystal sag control agent, where the polyurea crystal sag control agent is a reaction product of an amine and an isocyanate, has a melting point of from about 50°C to about 150°C, and is present in an amount of from about 0.1 to about 4 mass percent based on total weight of the coating composition, and where the coating composition has wet film thickness of at least about 30 microns measured at about 45 degrees without visible sag.SELECTED DRAWING: None
