Claims
- 1. A two-pack type curable composition comprising:
- 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, 2,4,6-tris-(dimethylaminomethyl)phenol as a curing agent for an epoxy resin and (A-3) calcium carbonate, 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) a mixture of calcium carbonate and at least one carboxylic acid.
- 2. The two-pack type curable composition according to claim 1, wherein said silicon-containing group is represented by the formula: ##STR39## wherein X is a hydroxyl group or a hydrolyzable group, R.sup.1 is a monovalent hydrocarbon group having 1 to 20 carbon atoms or a triorganosiloxy group of the formula: R.sup.2.sub.3 --Si--O-- in which R.sup.2 is a monovalent hydrocarbon group having 1 to 20 carbon atoms, "a" is 0, 1, 2 or 3, "b" is 0, 1 or 2 provided, that the total of "a" and "b" is at least 1 and "m" is 0 or an integer of 1 to 19, provided that when two or more R.sup.1 groups are present, they may be the same or different, that when two or more X moieties are present, they may be the same or different, that when two or more bracketed groups are present, they may be the same or different, and "b" may be the same or different when "m" is two or more.
- 3. The two-pack type curable composition according to claim 1, wherein said silicon-containing group is a group of the formula: ##STR40## wherein R.sup.1 and X are the same as defined above, and "c" is 1, 2 or 3.
- 4. The two-pack type curable composition according to claim 2, wherein the hydrolyzable group is an alkoxy group.
- 5. The two-pack type curable composition according to claim 1, wherein the organic elastomeric polymer comprises a backbone of a polyether.
- 6. The two-pack type curable composition according to claim 5, wherein the organic elastomeric polymer comprises a backbone of polypropylene oxide.
- 7. The two-pack type curable composition according to claim 1, wherein the organic elastomeric polymer comprises a backbone of polyalkyl acrylate.
- 8. The two-pack type curable composition according to claim 1, wherein the epoxy resin is at least one selected from a bisphenol-A type epoxy resin and a novolak type epoxy resin.
- 9. The two-pack type curable composition according to claim 1, further comprising an acidic filler which is at least one selected from the group consisting of titanium oxide and clay.
- 10. The two-pack type curable composition according to claim 1, wherein the carboxylic acid is a higher fatty acid having 8 to 40 carbon atoms.
- 11. The two-pack type curable composition according to claim 2, wherein the total of "a" and "b" is from 1 to 4.
