  • Publication number: 20120045652
    Abstract: Single-component compositions are disclosed, which can be cured in two stages, wherein in the first curing stage, compositions pre-cured by means of moisture and having in particular plastic properties are formed, and wherein in the second curing stage, compositions cured by means of heat and having in particular elastic properties are formed. The two-stage compositions are suitable in particular as adhesives and have the great advantage that thanks to said two-stage compositions, an adhesive can be applied to a substrate, said adhesive cures by means of moisture in such a way that it can be handled and stored without problems, and said adhesive can be cured easily in an adhering step by means of heat only when needed.

  • Publication number: 20120012251
    Abstract: The present invention relates to curable compositions comprising at least one specific blocked amine, at least one surface-deactivated polyisocyanate that is solid at ambient temperature and optionally water or a water-producing substance. Compositions of this type are characterized by an extremely high storage stability as long as they are not heated. Hot curing compositions that cure with the action of heat can thus be produced. Heat-activated compositions can also be produced. When heat is applied the latter compositions are not cured but are activated so that they are able to cure under the influence of moisture. The curable compositions are particularly suitable for use as adhesives.
