Abstract
An adhesive bond is produced using an adhesive composition which comprises a silane-grafted, largely amorphous poly-.alpha.-olefin prepared by grafting onto said largely amorphous poly-.alpha.-olefin a silane compound having from 1-3 alkoxy groups attached directly to the silicon and at least one olefinic double bond containing moiety, and then crosslinking the adhesive composition by means of water.
Claims13
A process for producing an adhesive bond between objects, comprising:
- applying to the objects an adhesive composition comprising a silane-grafted, largely amorphous poly-.alpha.-olefin, wherein the silane to be grafted on the amorphous poly-.alpha.-olefin has at least one olefinic double bond containing moiety and from 1-3 alkoxy groups attached directly to the silicon, and
- permitting moisture, as it is absorbed by the applied adhesive composition, to cause crosslinking within the adhesive composition.
A method of bonding two or more surfaces, comprising:
- a) applying an adhesive composition comprising a silane-grafted, largely amorphous poly-.alpha.-olefin, wherein the silane to be grafted on the amorphous poly-.alpha.-olefin has at least one olefinic double bond containing moiety and from 1-3 alkoxy groups attached directly to the silicon to said surfaces and joining the surfaces together, and
- b) crosslinking the adhesive composition by means of water.
