Abstract
A multilayer coating system for metal substrates is described. The coating system includes a digital printed coating layer applied to the substrate and a clear coating layer applied over the digital printed coating layer. The digital printed coating layer is applied using a jet process and the inks used are inorganic inks. The described multilayer coating system demonstrates a color change (ΔE) of no more than 5 units.
Claims12
A multi-layer weatherable coating system comprising:
- a basecoat layer comprising at least one polyester resin component applied on a planar metal surface that forms at least part of a garage door;
- a patterned coating comprising an ink composition deposited over the basecoat layer on the planar metal surface, wherein the ink composition comprises a 100% solids inorganic ink system;
- and
- an electron beam-cured clear coating layer comprising 20 to 40% by weight of a urethane (meth) acrylate resin component applied over the patterned coating,
- wherein the electron beam-cured layer is applied in a coil coating process, the patterned coating is applied by a process integrated into the coil coating application process, and wherein the coating system demonstrates a color change (ΔE) of no more than 5 units on exposure to UV radiation of at least 500 hours.
