Abstract

A one-pack moisture-curing epoxy resin composition which can be cured at ordinary temperatures and is improved in storage stability without impairing the quickness of curing, i.e., is excellent in two properties incompatible with each other. This composition includes one ore more members selected from the group consisting of vinyl carboxylates of the general formula (1) and epoxy-containing silyl compounds of the general formula (2), one or more members selected from the group consisting of ketimines and oxazolidines, and an epoxy resin. (1) [In the general formula (1), R1, R2, R3, and R4 are each independently hydrogen or an organic group; and n is an integer of 1 or above] (2) [In the general formula (2), R5 and R6 are each independently alkyl; R7 is an epoxy-containing organic group; and n is an integer of 1 to 3]

Claims1

Dependent claims

A one-pack moisture curable epoxy resin composition comprising:

(a) a vinyl carboxylate compound represented by the following chemical formula (1),
(b) one or two or more compounds selected from the group consisting of a ketimine compound represented by the following chemical formula (4) which is obtained by reaction of a carbonyl compound represented by the following chemical formula (3) with an amine compound having a primary amino group, and an oxazolidine compound represented by the following chemical formula (5) which is obtained by dehydration condensation of a carbonyl compound and an aminoalcohol compound, and
(c) an epoxy resin:
wherein R1, R2, R3 and R4 are each a hydrogen atom or an organic group and they may be the same or different, and
n is an integer of 1 or more,
wherein R8 and R9 are each an alkyl group and they may be the same or different,
wherein R10 is a residue excluding a primary amino group of an amine compound,
R8 and R9 are each an alkyl group and they may be the same or different, and
n is an integer of 1 or more, and
wherein R11, R12, R13, R14 and R15 are each a hydrogen atom or an organic group.
