Abstract

A coating composition, a process for producing it and substrate coated therewith are described. The composition comprises a multimodal ethylene polymer, which contains from 80 to 99.8% by weight of ethylene repeating units and from 0.2 to 20% by weight of C3-C20 α-olefin repeating units, and is a blend of at least a first and a second ethylene polymer prepared by polymerization in the presence of a single site catalyst system.The blend has a density of 0.915-0.955 g/cm3, a melt flow rate, MFR2, of 0.028-1.5 g/10 min., a molecular weight distribution, Mw/Mn, of 3-10, and a CTL 5.0 MPa-value according to ISO 6259 of at least 500 hrs.
