Zusammenfassung: | The present invention relates to an adhesive composition comprising at least one silylated polymer (A) comprising at least one group of formula (I), preferably at least two groups of formula (I):-Si (R4) p (OR5) 3-p wherein: each R4 independently represents a linear or branched alkyl group comprising from 1 to 4 carbon atoms; each R5 independently represents a linear or branched alkyl group comprising from 1 to 10 carbon atoms and optionally comprising one or more heteroatoms selected from oxygen and nitrogen, or two OR5 groups are involved in the same ring comprising from 2 to 8 carbon atoms; p is an integer equal to 0, 1 or 2; and at least one catalyst (B) of formula (V): B (OH) R 'R "wherein: R' represents a substituted or unsubstituted aryl group; and R ''is selected from OH groups and substituted or unsubstituted aryl groups. The invention also relates to the use of said composition as an adhesive or as a coating; an article comprising at least one layer obtained by crosslinking said composition; and a m |
