Multi-components adhesives, manufacturing thereof, and applications thereof

摘要

A multi component adhesive comprises uncured pre-gel that comprising at least one water miscible cross-linkable polymer selected from at least one of a naturally existing form of a carbohydrate, a synthetically prepared form of carbohydrate and a salt of a polysaccharide, and at least one water- insoluble salt of a cross linking agent; and a composition comprising at least one trigger compound capable of triggering dissolution of the salt of the cross linking agent into the pre-gel; wherein the uncured pre-gel applied to a first surface is capable of curing and increasingly adhering to the first surface after adding the composition comprising the trigger compound to the uncured pre-gel.
