Abstract
The object of the present invention is to significantly improve weather resistance over a long period of time of the cured product of the invention, while maintaining physical properties, such as tensile properties and rubber-like elasticity, at levels required of sealing compositions for use in general buildings. The curable composition of the invention is a curable composition which comprises a vinyl polymer having a reactive silicon containing group (a), such as a (meth) acrylic polymer having a reactive silicon containing group, a polyoxyalkylene polymer having a reactive silicon containing group (b), such as a polyoxypropylene having a reactive silicon containing group, and a plasticizer having an acrylic component (c), such as an acrylic polymer, and is reacted and crosslinked in the presence of moisture to provide a rubbery cured product.
