Intercrossing resin/curing agent adhesive systems
Abstract
Abstract Novel adhesive systems are disclosed which pertain to combinations of more than one curable resin and the curing agents corresponding thereto. The disclosed adhesive systems comprise separated reactive components wherein: (a) a first reactive polymeric material is combined with a curing agent for a second reactive polymeric material to yield one component and; (b) the second reactive polymeric material is combined with a curing agent for the first reactive polymeric material to form another component. Several embodiments relating to intercrossing combinations of the two components are disclosed. In all of the embodiments, when the reactive materials from two components are combined, the curing agents react with their respective, intercrossed, reactive polymeric material to yield strong adhesive bonds. Of particular interest in this invention are embodiments of the adhesive systems which pertain to a rapidly curing adhesive and especially to such an adhesive for use underwater.
