Adhesive composition that can be peeled after crosslinking

An adhesive composition comprising:

• (i) from 58 to 80% by weight of a moisture-crosslinkable polymer (A) comprising at least:
• as main chain, a polyurethane (A2) having a number-average molecular weight between 600 Da and 60 kDa, being the condensation product of a polyether polyol and/or a polyester polyol with polyisocyanates, and
• an alkoxysilane terminal radical of formula (I),
• —Si(R1)p(OR2)3-p (I)
• in which:
• R1 and R2, which are identical or different, each represent a linear or branched alkyl radical having 1 to 4 carbon atoms, and when there are multiple R1 radicals, the R1 radicals may be identical or different, and when there are multiple R2 radicals, the R2 radicals may be identical or different;
• p is an integer equal to 0, 1 or 2;
• said alkoxysilane radicals being connected to the main chain directly by its available bond or indirectly
• (ii) from 8 to 20% by weight of a silica (B) having a BET specific surface area between 150 and 250 m2/g;
• (iii) from 4 to 15% by weight of an oligomer of a vinyl derivative of an alkoxyalkylsilane (C) having a number-average molecular weight between 500 Da and 5 kDa,
• (iv) from 0.01 to 3% by weight of a crosslinking catalyst (D), and
• (v) from 0.1 to 5% by weight of rubber granulates of non-spherical shape having a size between 0.5 and 2 mm.
