Abstract:
1. A polymer coated pipe comprising an inner surface, an outer surface layer (A) and a coating layer (B) covering said outer surface layer (A) wherein the coating layer (B) comprises a coating composition (B-2) comprising a multimodal ethylene copolymer (B-1), being a copolymer of ethylene and one or more alpha-olefin comonomers having from 4 to 10 carbon atoms, wherein the multimodal ethylene copolymer (B-1) has a weight average molecular weight of from 70000 g/mol to 250000 g/mol, the ratio of the weight average molecular weight to the number average molecular weight, Mw/Mn, of from 15 to 50, a melt index MFR 2 , determined according to ISO 1133 at 190° C. under a load of 2.16 kg, of from 0.05 g/10 min to 5 g/10 min, a melt index MFR 5 , determined according to ISO 1133 at 190° C. under a load of 5 kg, of from 1.0 to 10 g/10 min and a density of from 930 kg/m 3 to 955 kg/m 3 .
