Patent number: 8450411Abstract: A solvent-free and anhydrous hardenable composition that contains at least one polymer A. Polymer A being obtainable by reacting a polyether with at least one ethylenically unsaturated silane in the presence of a radical starter, the ethylenically unsaturated silane carrying at least one hydrolyzable group on the silicon atom. The composition provides low viscosity prior to curing along with good elasticity after curing and a broad adhesion spectrum in a solvent-free and water-free hardenable composition. Also methods for producing the composition and use of the composition as an adhesive, sealant, or coating agent.Type: GrantFiled: December 12, 2011Date of Patent: May 28, 2013Assignee: Henkel AG & Co.
