CA 2748723

The present invention relates to an article coated with a composition comprising (A) an ethylene homo- or copolymer resin which has been prepared by using a single-site catalyst further characterized in that component (A) has an MFR21,measured according to ISO 1133 at 190°C and under a load of 21.6 kg, from 0.01 to 20 g/10 min. The present invention further relates to an article coated with a composition comprising (A) an ethylene homo- or copolymer resin which has been prepared by using a single-site catalyst further characterized in that component (A) has an impact strength at -40 °C of at least 80 kJ/m2 in a Charpy notched test according to ISO ISO 179-1/1eA:2000 with a pendulum energy of 15 J. The invention is furthermore directed to the use of the composition for the coating of an article.

La présente invention concerne un article revêtu d'une composition comprenant (A) une résine d'homopolymère ou de copolymère d'éthylène synthétisée avec un catalyseur à site unique, ladite composition étant en outre caractérisée en ce que le composant (A) présente un MFR21, mesuré selon ISO 1133 à 190 °C et sous une charge de 21,6 kg, compris entre 0,01 et 20 g/10 minutes. La présente invention concerne en outre un article revêtu d'une composition comprenant (A) une résine homopolymère ou copolymère synthétisée avec un catalyseur à site unique, ladite composition étant en outre caractérisée en ce que le composant (A) présente une résistance impact à -40 °C d'au moins 80 kJ/m2 dans un essai de flexion par choc sur éprouvette entaillée Charpy selon ISO 179-1/1eA:2000 avec une énergie de pendule de 15 J. L'invention concerne en outre l'emploi de la composition dans le revêtement d'un article.
