Abstract: PVC-free coil coated steel having excellent cut-side corrosive resistance can be prepared by using on one or both sides a primer composition essentially consisting of a linear polyester of Mn=3,000-15,000, of acid number 0-10, and hydroxyl index 10-25; a blocked polyisocyanate, melamine or an urea-formaldehyde adduct, in an equivalent ratio of 0.8-4.0 to polyester; a catalyst; anti-corrosive pigments of the chromate type, being at least 50 weight percent of all pigments; and solvents.

Abstract: The invention relates to a cathode (1) intended for spraying thin layers of materials onto one or more substrates using the cathodic sputtering method.It consists of a structure (V-shaped) comprising an electrical supply, cooling members and two sputtering planes (6, 7) in which there are arranged side by side at least two strips of target material joined at their ends forming a single continuous target material track extending between and positioned in at least two separate planes, the track being confined within a single magnetic circuit, which also extends between and is positioned in the at least two separate planes, with the result that it is possible to treat simultaneously two substrates (44) arranged on their supports (43) on each side of the cathode (1).The cathode (1) according to the invention is particularly recommended for sputtering substrates of large size, such as glass.
