A non-stick coating with improved scratch resistance comprises an undercoat applied to a substrate, coated with a primary coat comprising a fluorocarbon resin and one or more fluorocarbon resin-based outer coats. The undercoat comprises at least 50% by weight of the polymer oxy-1,4-phenylene-oxy-1,4-phenylene-carbonyl-1,4-phenylene, known as PEEK, and is free of fluorocarbon resin.

Antiadhesive coating with improved scratch resistance

A non-stick coating with improved scratch resistance comprises an undercoat applied to a substrate, coated with a primary coat comprising a fluorocarbon resin and one or more fluorocarbon resin-based outer coats, characterized in that the undercoat is exclusively constituted by the polymer oxy-1,4-phenylene-oxy-1,4-phenylene-carbonyl-1,4-phenylene, known as PEEK.

Non-stick coating with improved scratch resistance

The process permits applying a fluorocarbonated resin base coating on a flat metallic support (4). According to the invention, this coating is applied in a continuous manner, directly on the support (4) by serigraphy. Use particularly to coat cooking utensils with a layer of fluorocarbonated resin. (See FIG. 2).

A smoothing or pressing or steam iron having a metallic sole-plate that comes into contact with articles to be ironed and has a series of substantially parallel ribs (6, 7) whose width and height are within the range of a few tenths of a millimeter to a few millimeters. The sole-plate has an exposed surface having a continuous anti-adhesive coating (8) selected from the group consisting of fluorocarbon resin and enamel. The coating follows the profile of the ribs. The ribs extend in a longitudinal direction of the sole-plate. Each rib has either a rounded crest or a pointed crest.

The smoothing or pressing or steam iron has a metallic sole-plate (1) provided with an anti-adhesive coating (2). The sole-plate surface overf the anti-adhesive coating has a series of projections (3) formed by an anti-adhesive coating based on fluorocarbon resin, with the result that the iron glides easily over textile fabrics.
