Abstract
Abstract The invention provides a curing agent for two-pack type curable composition use having excellent storage stability, and also provides a curing agent composition which comprises a hydrolyzable silyl group-containing compound (a), a non-phthalic acid ester based plasticizer (b) having no phthalic acid ester structure in its molecule, and a bivalent tin based curing catalyst (c), that satisfies all of mechanical properties, recoverability and adhesiveness to substrate, can be mixed easily when used and has excellent storage stability, and a two-pack type curable composition which hardens when a base resin composition comprising a curable organic polymer (d) having in its molecule a functional group crosslinkable by a reaction catalyzed by a bivalent tin based curing catalyst (c), an epoxy group-containing silane compound (f) and an epoxy compound (g) is mixed with the above curing agent composition.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
36 words
A curing agent composition which comprises a
hydrolyzable silyl group-containing compound (a), a non-phthalic
acid ester based plasticizer (b) having no
phthalic acid ester structure in its molecule, and a
bivalent tin based curing catalyst (c).
Claim 2
Dependent Claim
