Patent ID: 11034870

Abstract:
A composition curing upon exposure to moisture comprises (A) one or more at least bifunctional silane compounds with at least two alkoxysilane groups, (B) at least one monofunctional silane compound with only one alkoxysilane group, and/or a partially condensed or bridged derivative thereof, and (C) at least one acid generator which, upon exposure to actinic radiation or heat, releases an acid. In addition, further additives (D) may be contained in the compositions according to the present invention. The composition is liquid at room temperature and, apart from the latent acid generator, does not contain any further catalysts for moisture-curing of alkoxysilanes. After activation of the acid generator the composition cures in the presence of moisture, while remaining liquid at room temperature in the presence of humidity over a period of at least 24 hours prior to activation of the acid generator. Furthermore, a method of joining or casting structural elements using the composition is described.
