Abstract
Abstract A hardenable composition for use as an adhesive, putty, molding compound, sealer and for coating purposes composed of the reaction product of a monomeric, oligomeric or polymeric carboxylic acid and a compound of a metal of the second group of the periodic system which are capable of forming salts and a hardening agent. One or all of the components can be in protective sheaths or microencapsulated to prevent the hardening until the rupture thereof.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
156 words
A composition suitable for use as an adhesive, putty, sealing, or coating material consisting essentially of the reaction product of: a) a hardenable component selected from the group consisting of unsaturated monomeric, oligomeric, or polymeric carboxylic acids and esters thereof having an acid number in excess of 0.1; with at most a stoichiometric amount of b) a salt forming component of a metal of the second group of the periodic system; and c) a pulverulent olefin polymer selected from the group consisting of polyolefin copolymers with acrylates or vinyl acetate and a grafted polyolefin copolymer grafted with acrylic or methacrylic compounds, the olefin polymer being present in an amount from 0.1 to 50% by weight based on the weight of the reaction product, which composition further contains a hardening agent and wherein the reaction product, the hardening agent or both are contained in rupture protective sheaths which prevent their reaction with one another until rupture thereof.
Claim 2
Dependent Claim
