Japanese Patent JP2020066708
Kind Code:
A
Abstract:
To provide a curable composition which contains a polyoxyalkylene-based polymer having a hydrolyzable silicon group and a (meth)acrylic polymer having a hydrolyzable silicon group, and suppresses a change in tensile physical property after construction when being used as a sealing material to a porous base material.SOLUTION: A curable composition for sealing material to a porous base material contains (A) a polyoxyalkylene-based polymer having a hydrolyzable silicon group, (B) a (meth)acrylic polymer having a hydrolyzable silicon group and (C) a polyoxyalkylene-based polymer plasticizer having a number average molecular weight of 2,000-15,000 and a ratio of hydroxyl groups in terminal groups of 10% or less.SELECTED DRAWING: None
