Problems solved by technology

[0009] Alternatively, it is also conceivable to reduce water absorption by using (meth)acrylic monomers with a high glass transition temperature (Tg), or to improve adhesion by adding a coupling agent. However, these countermeasures have produced Other problems such as decrease in initial adhesive strength or poor storage stability

Embodiment

[0033] Hereinafter, the effects of the present invention will be described in detail using examples, but the present invention is not limited to these examples.

[0034] The (meth)acrylic curable compositions in Examples 1 to 7, Reference Examples 1 to 6, and Comparative Examples 1 to 3 were prepared from the following components in accordance with the additive amount ratios shown in Tables 1 and 2. In addition, the numerical value described in a table|surface is the addition weight part of each component.

[0035] 2-Hydroxyethyl methacrylate (manufactured by Nippon Catalyst Co., Ltd., trade name HEMA) as component (a) and ethylenediaminetetraacetic acid (manufactured by Dojin Chemical Laboratory Co., Ltd.) as component (b) and its comparative component were used. trade name 4H), ethylenediaminetetraacetic acid disodium salt (manufactured by Dojin Chemical Laboratory Co., Ltd., trade name EDTA2NA), sodium lauryl sulfate (Wako Pure Chemical Industries, Ltd. products), sodium s...

Abstract

The present invention relates to a curable (meth)acrylic composition comprising (a) a (meth)acrylic acid ester monomer or oligomer containing at least one hydroxyl group in the molecule, (b) a chelating compound that is not a metal salt, and (c) a surfactant.

Description

technical field [0001] The present invention relates to a curable composition mainly composed of a (meth)acrylic functional compound suitable for adhesive and sealing applications, which can maintain storage stability in an uncured state and can improve Humidity strength of cured product. Background technique [0002] Curable compositions having (meth)acrylic functional groups, cured by polymerization of (meth)acrylic functional groups, in particular anaerobically curable compositions, based on (meth)acrylate monomers , and has the property of maintaining a long-term stable liquid state without gelling during contact with air or oxygen (hereinafter, simply referred to as air), but solidifies rapidly when the air is blocked or excluded. The above-mentioned curable composition is used for gluing and fixing screws, bolts, etc.; bonding of fitting parts; gluing and sealing between flange faces; filling of nest holes generated in castings, etc. [0003] Anaerobic curable compos...
