Abstract
Abstract A two-pack type curable composition comprising: A. a first composition containing (A-1) an organic elastomeric polymer having at least one silicon-containing group to the silicon atom of which a hydroxyl group and/or a hydrolyzable group are bonded and which is cross linkable through formation of a siloxane linkage in a molecule and (A-2) a curing agent for an epoxy resin, and B. a second composition containing (B-1) an epoxy resin, (B-2) a curing catalyst for the organic elastomeric polymer having at least one silicon-containing reactive group and (B-3) at least one member selected from the group consisting of acidic fillers and carboxylic acids, which has good storage stability.
