Patent ID: 8691909

Claim:
A heat-curable adhesive composition comprising: from 20 to 85% of a polyether (A) comprising 2 hydrolysable alkoxysilane-type end groups, having a viscosity, measured at 23° C., ranging from 25 to 40 Pa·s and of formula (I): in which: R 1 and R 2 , which are identical or different, each represent a linear or branched alkyl radical having 1 to 4 carbon atoms, with the possibility, when there are several R 1 (or R 2 ) radicals, that these are identical or different; R 3 represents a linear alkylene divalent radical comprising from 1 to 6 carbon atoms; R 4 represents a linear or branched alkylene divalent radical comprising from 1 to 4 carbon atoms; n is an integer such that the number-average molecular weight M n of the polymer of formula (I) is between 20 kDa and 40 kDa; p is an integer equal to 0, 1 or 2; from 15 to 80% of a compatible tackifying resin (B), having a number-average molecular weight between 200 Da and 10 kDa; and from 0.01 to 3% of a curing catalyst (C).
