Abstract

The purpose of the present invention is to provide an anaerobic curable resin composition having characteristics whereby a cured product thereof is fragile and easily made into fine particles. An anaerobic curable resin composition containing the following components (A)-(D): component (A): a compound having radical polymerizable functional groups; component (B): a radical polymerization initiator; component (C): an anaerobic polymerization accelerator; and component (D): a nonionic surfactant.

Description

technical field [0001] The present invention relates to an anaerobic curable resin composition having characteristics such that a cured product is relatively brittle and easily pulverized. Furthermore, this invention relates to the sealant for Wilchshire using the above-mentioned anaerobic curable resin composition. Background technique [0002] The anaerobic curable resin composition is composed mainly of a compound having a radically polymerizable functional group such as (meth)acrylate, and has the following properties: it is relatively stable during contact with oxygen present in the air, and does not It will remain in a liquid state for a long period of time due to gelation, etc., and radical polymerization will proceed rapidly if oxygen is blocked. Utilizing such properties, the above-mentioned anaerobic curable resin composition is used for bonding and fixing screws, bolts, etc.; fixing, bonding, and sealing of fitting parts; filling of pores that may occur in cast p...
