Abstract
The present invention provides a sealant composition that includes a reactive silyl group-containing organic polymer, and gives a cured product having a low modulus and not having wrinkles or cracks on the surface even though the sealant includes as a curing catalyst a tetravalent tin compound, which is presumed to reduce recovery. The sealant composition is a one-component curable sealant composition including: a linear organic polymer (A) having a number average molecular weight of 11,000 to 30,000, and having an ethanol-elimination reactive silyl group at a molecular terminal; a tetravalent tin compound (B); and a plasticizer (C).
