Abstract
An anti-corrosion composition includes a first compound including: a first polyisobutylene having an average relative molar mass ranging from about 30,000 to about 100,000 g/mole and a Staudinger index ranging from about 15-70 cm/g, a first depolymerized butyl rubber with Brookfield viscosity at 66° C. ranging from about 400,000-2,000,000 mPa·s and an average molecular weight ranging from about 20,000-60,000, and combinations thereof. A second compound includes a second polyisobutylene having an average relative molar mass ranging from about 900,000-6,500,000 g/mole and a Staudinger index ranging from about 240-900 cm/g, at least one second partly cross-linked butyl rubber with a Mooney viscosity at 127° C. ranging from about 65-100 MU. The anti-corrosion composition includes at least one first or at least one second polyisobutylene as well as at least one first or at least one second butyl rubber.
