Abstract:
1. A moisture free, moisture-curable, single component, room temperature vulcanizable composition which is storage stable with exclusion of water and cures to a solid elastomer in the presence of water, comprising: (A) at least one compound of the formula where A is an x-valent organic radical bonded to —CR R each independently is a monovalent, optionally substituted hydrocarbon radical, R R x is an integer from 1 to 10, a is 0, 1 or 2, (B) at least one compound which contains at least one basic element of main group 5, selected from the group consisting of (B1) compounds comprising basic nitrogen and (B2) compounds comprising basic phosphorus, (C) at least one acid selected from the group consisting of (C1) phosphorus acids of the formula and/or condensates thereof with one or more P—O—P bonds and (C2) carboxylic acids of the formula where R R R q is 0, 1 or 2, r is 1, 2 or 3 and q+r is 1, 2 or 3, and (D) at least one silane of the formula and/or partial hydrolyzates thereof, where X is a monovalent organic radical bonded to —CR R R′ each independently is as defined for R, Y each independently is a hydrolyzable radical, and b is 0, 1 or 2, wherein the pH of the mixture of components (B), (C), and (D) is less than or equal to 7.
