Curable composition
View Patent ↗It is an object of the present invention to provide a two-component curable composition whose component A is easy to be handled, and which shows excellent internal curability and good storage stability. This problem is solved using a two-component curable composition, comprising component A comprising 100 parts by weight of an organic polymer containing a reactive silicon group, (B) 0.1-300 parts by weight of an epoxy group-containing compound, and (C) 0.1-20 parts by weight of water, and component B comprising (D) 0.1-20 parts by weight of a curing catalyst, and (E) 0.1-200 parts by weight of an amine compound.
1. A production method for a curable composition, comprising storing each of a component A and a component B for one month, and then mixing them;
wherein component A comprises
(A) 100 parts by weight of an organic polymer containing a reactive silicon group of the following general formula (1):
—Si(R 1 3-a )X a (1)
where R 1 represents an alkyl group of 1 to 10 carbon numbers, an aryl group of 6 to 10 carbon numbers, or an aralkyl group of 7 to 10 carbon numbers, X represents a hydroxy group or a hydrolyzable group, and the subscript a is 1, 2, or 3;
(B) 0.1-300 parts by weight of an epoxy resin, and
(C) 0.1-20 parts by weight of water, and
component B comprises
(D) 0.1-20 parts by weight of a curing catalyst, and
(E) 0.1-200 parts by weight of an aliphatic aromatic amine compound;
wherein the curing catalyst is a tetravalent tin compound; and
wherein the main chain skeleton of constituent (A) comprises a polyoxyalkylene polymer and/or an alkyl (meth)acrylate ester polymer.
2. The production method for a curable composition according to claim 1 , wherein the component A and/or component B further comprise(s) (F) 0.1-20 parts by weight of a silane coupling agent.
3. The production method for a curable composition according to claim 1 , wherein the component A and/or component B further comprise(s) (G)50-800 parts by weight of an inorganic filler.
4. The production method for a curable composition according to claim 1 , wherein the component A and/or component B further comprise(s) (H) 1-300 parts by weight of a plasticizer.
5. The production method for a curable composition according to claim 2 , wherein the component A and/or component B further comprise(s) (G) 50-800 parts by weight of an inorganic filler.
6. The production method for a curable composition according to claim 2 , wherein the component A and/or component B further comprise(s) (H) 1-300 parts by weight of a plasticizer.
7. The production method for a curable composition according to claim 3 wherein the component A and/or component B further comprise(s) (H) 1-300 parts by weight of a plasticizer.
8. The production method for a curable composition according to claim 1 , wherein the tetravalent tin compound is an organotin compound.
9. The production method for a curable composition according to claim 1 , wherein the curable composition is a sealing material.
10. The production method for a curable composition according to claim 1 , wherein the curable composition is a coating material.
11. The production method for a curable composition according to claim 1 , wherein the curable composition is an adhesive material.
