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.

Two-pack type curable composition and hardener therefor

To provide curable resin compositions capable of exhibiting a low modulus, a high break strength, a high elongation and a satisfactory water-resistant adhesiveness to mortar. One of which includes (a) an organic polymer having at least one reactive silicon group in one molecule, (b) an amino group-substituted silane compound, and (c) an epoxy group-substituted silane compound; and another of which includes (a) an organic polymer having at least one reactive silicon group in one molecule, (b) an amino group-substituted silane compound, (c) an epoxy group-substituted silane compound, and (d) an epoxy resin.

Curable resin compositions

A one-pack type curable resin composition having high adhesive strength to various substrates, good storage stability and excellent restoring properties is disclosed. The one-pack type curable resin composition contains an organic polymer (a) having at least one reactive silicon group per molecule, a compound (b) having reactive silicon group in its molecule, a non-phthalate plasticizer (c) having no phthalate structure in its molecule, and a stannous curing catalyst (d).
