Abstract: An epilamization agent containing at least one compound including at least hydrophobic and oleophobic moieties arranged to impart epilame properties to the compound, and at least one hydrophilic moiety arranged to make the compound soluble in aqueous medium, the hydrophilic moiety being linked to the compound by at least one cleavable group. A method for coating a substrate with epilame, including: preparing an aqueous epilamization bath by solubilising such an epilamization agent, placing the substrate in contact with the epilamization agent in the epilamization bath, separating the hydrophilic moiety from the epilamization agent by cleavage, rinsing the substrate to eliminate the hydrophilic residues from the hydrophilic moiety and drying.

Abstract: The invention relates to a copolymer and a substrate having a surface, at least one part of which is coated with an epilame agent comprising at least one compound in the form of a copolymer comprising V units, N units, optionally at least one M unit, and optionally at least one P unit, linked by covalent bonds by their main chains, wherein wherein W, X, Y, Z are spacer arms, T is a tracer group arranged to determine the concentration of epilame agent in an epilame-coating bath, L is a halogenated, preferably fluorinated, C1-C20 carbon moiety, A is a substrate anchoring moiety, Q is H, CH3, or a hydrocarbon chain different from T. The invention also concerns a method for coating such a substrate with epilame, said method comprising a step of checking the concentration of epilame agent in the epilame-coating bath by means of the tracer group and if necessary, a step of readjusting the concentration of epilame agent in the epilame-coating bath.

Abstract: An in-line method for marking a substrate made of extruded synthetic material, the method including the steps of extruding the synthetic material through an extrusion die to form the substrate, marking the substrate by scrolling the substrate obtained from the extrusion die between two rotatably mounted and temperature-controlled rollers with an upper roller and a lower roller, one of the rollers having an impression forming the negative of a decoration or a texture to be marked on one face of the substrate, this same roller or the other of the rollers including at least one notch allowing to guide the substrate as it passes through the extrusion die and between the two rollers. An installation can include in line the extrusion die and the marking device.

Abstract: A method for manufacturing an external component for watches or jewellery, especially a bracelet, includes the steps of: providing a substrate including a first face opposite to a second face and co-extrusion coating the first face and the second face of the substrate respectively with a first and a second band of synthetic material. The first band forms on the first face a transparent or translucent layer so that all or part of the substrate remains visible.
