The present disclosure relates to a method of reactivating the surface of an organic paint coating, a method of facilitating adhesion of a further coating to the organic paint coating, and a substrate having a reactivated organic paint coating. There is also disclosed a surface reactivation treatment for an organic paint coating. The reactivation method also facilitates adhesion of the organic paint coating to further coating(s) across a broad application window.

Surface reactivation treatment

A method of treating a contoured surface with surface treatment layer includes applying a surface preparation layer along the contoured surface and applying a basecoat layer on top of the surface preparation layer. The method further includes stabilizing the basecoat layer to prepare a basecoat surface along the basecoat layer for one or more subsequent layers of the surface treatment coating and jetting a decorative livery layer along the contoured surface using one or more ink jet print heads. The method further includes applying an adhesion promoter on top of the decorative livery layer and stabilizing the adhesion promoter layer to produce a desired bonding surface along the adhesion promoter layer. Additionally, the method includes applying a clear coat layer to cover the underlying decorative livery layer, the basecoat layer and the surface preparation layer.

Inkjet printed livery application process

A coating includes at least one coating layer containing first particles, second particles, and third particles distributed throughout a cross-linked, continuous polymer matrix. An outer surface of the coating layer includes surfaces of at least first particles extending outward from a top periphery of the polymer matrix. The outer surface exhibits a property of delaying ice formation compared to the coating layer without the first particles. A method includes applying a coating composition in one application step. The one-step coating composition contains first particles, second particles, and third particles in a base containing a polymer. A coating composition includes first particles, second particles, and third particles distributed in a matrix precursor.
