CA 2605517
The invention relates to moisture-curable compositions that are provided with increased elasticity while having good mechanical properties and adhesion. Said compositions contain at least on silane-functional polymer A, at least one aminosilane AS2, and at least one .alpha.-functional organodialkoxysilane at an amount of 0.6 to 5.0 parts by weight relative to 100 parts by weight of polymer A. Also disclosed are the production and use of the inventive compositions, especially as a sealant and adhesive.
L'invention concerne des compositions durcissant à l'humidité présentant une expansibilité accrue tout en possédant de bonnes propriétés mécaniques et une bonne adhérence. Ces compositions contiennent au moins un polymère A à fonction silane, au moins un aminosilane AS2 et au moins un organodialcoxysilane à fonction .alpha. dans une quantité comprise entre 0,6 et 5,0 parties en poids, par rapport à 100 parties en poids du polymère A. L'invention concerne en outre la production et l'utilisation de ces compositions, en particulier comme agent d'étanchéité et comme adhésif.
