## Abstract

A curable composition which comprises (A) a silyl group containing vinyl resin which has a main chain consisting essentially of vinyl polymer and has in one molecule at least one silicon atom connected to a hydrolyzable group on the terminal or side chain, (B) a tin compound, and (C) an amine or a mixture of two or more amines having in one molecule at least one silicon atom connected to a hydrolyzable group. The composition is useful as a coating material, adhesive, sealant, paints, and the like.

## Claims

### Claim 1

A curable composition comprising a blend consisting essentially of (A) a silyl group containing vinyl resin having a main chain consisting essentially of vinyl polymer and in one molecule at least one silicon atom connected to a hydrolyzable group on terminal or side chain; (B) a tin compound; and (C) an amine or a mixture of two or more amines having in one molecule at least one silicon atom connected to a hydrolyzable group, wherein said vinyl resin comprises 100 parts by weight; said tin compound comprises 0.01 to 10 parts by weight; and said amine or mixture of amines comprises 0.01 to 20 parts by weight.

### Claim 2 (depends on 1)

The composition of claim 1, wherein said tin compound is an organotin compound of carboxylic acid type.

### Claim 3 (depends on 1)

The composition of claim 1, wherein said tin compound is an organotin compound of mercaptide type having a Sn.dbd.S bond.

### Claim 4 (depends on 1)

The composition of claim 1, wherein said tin compound is an organotin compound of sulfide type having a Sn.dbd.S bond.

### Claim 5 (depends on 1)

The composition of claim 1, wherein said amine is a silane coupling agent containing an amino group.

### Claim 6 (depends on 1)

The composition of claim 1, wherein said amine is a reaction product of a silane coupling agent containing an amino group and a silane coupling agent containing an epoxy group.

### Claim 7 (depends on 1)

The composition of claim 1, wherein said amine is a reaction product of a silane coupling agent containing an amino group and a compound containing an epoxy group.

### Claim 8 (depends on 1)

The composition of claim 1, wherein said amine is a reaction product of a silane containing an epoxy group and an amine.

### Claim 9 (depends on 1)

The composition of claim 1, wherein said amine is partial-hydrolyzates of silane coupling agent containing an amino group and a compound containing a hydrolyzable group.

### Claim 10 (depends on 1)

The composition of claim 1, wherein said tin compound comprises 0.1 to 8 parts by weight.

### Claim 11 (depends on 1)

The composition of claim 1, wherein said amine or mixture of amines comprises 0.1 to 15 parts by weight.
