PolyamidesUn polyamide est un polymère contenant des fonctions amides -C(=O)-NH- résultant d'une réaction de polycondensation entre les fonctions acide carboxylique et amine.
Selon la composition de leur chaîne squelettique, les polyamides sont classés en aliphatiques, semi-aromatiques et aromatiques. Selon le type d'unités répétitives, les polyamides peuvent être des homopolymères ou des copolymères.

| Résumé : |
Pre-finished metal, be it steel or aluminium, is commonly used globally. The majority is used as façades and roofs of buildings, but other uses include garage doors, caravans, gutters and domestic appliances. The pre-finishing takes place on lines consisting of a coil of relatively thin metal (commonly around 0.6 mm thick for steel and between 1 and 1.2m wide) that can run continuously. The coil of thin metal can have a mass of 20 tonnes for steel and be upwards of 3,000 m long. Hence, the alternative name for prefinishing is coil coating. |
