Patent

CA 2302934

The present invention has its object to provide a curable composition showing a controlled initial curing rate and, hence, offering good workability by introducing a methyl group into the neighborhood of the reactive silicon group within an oligomer to indirectly lower the reactivity of the reactive silicon group within the oligomer. The present invention is concerned with a curable composition comprising (A) a reactive silicon group-containing polyether oligomer and (B) a silanol condensation catalyst, said (A) reactive silicon group-containing polyether oligomer having a partial structure of the following general formula (1) per molecule: -O-R1-CH (CH3)-CH2-(Si(R2 2-b) (X b)O) m Si(R3 3-a )Xa (1)
