Abstract (en)
A method, comprising: - providing a first roll, a second roll, and a nip between the first and second rolls; - passing a substrate through the nip between the rolls at a predetermined line speed; - supplying a coating liquid to the substrate in the nip, wherein the coating liquid has a predetermined contact angle with the substrate; and - smoothing the coating liquid, via the nip, into a substantially uniform layer of liquid coating on the substrate, - providing that the substrate is a galvanized or galvannealed steel strip; - providing that a circumferential speed of a surface area of the rolls contacting the substrate substantially matches the line speed; and - providing that the contact angle of the coating liquid with the substrate is smaller than 97°.
