anti-corrosion composition, use of an anti-corrosion composition, method for obtaining corrosion protection on pipes and units comprising pipes, and wrapping tape.

摘要

The invention relates to an anti-corrosion composition comprising at least one first butyl rubber having an apparent viscosity according to brookfield measured at 66 ° C, according to dinen iso 2555, in a range of approximately 400,000 mpa · s. 2,000,000 mpa · having an average molecular weight in the range of approximately 20,000 to approximately 60,000 and at least a second butyl rubber having an average molecular weight in the range of approximately 150,000 to approximately 2,000,000 and a mooney viscosity ml (1 + 8) measured at 125 ° C in a range from approximately 25 mu to approximately 65 mu, measured according to iso 289.
