Binary adhesives comprising phenoxyethyl methacrylate and tetrahydrofurfuryl methacrylate, including structures of cured materials thereof

Abstract

The present disclosure provides a two-part adhesive capable of adhering over a wide temperature range near room temperature and exhibiting excellent adhesion on poorly adhering substrates including silicone rubber and the like strength. In some embodiments, the binary adhesive comprises: a main agent comprising phenoxyethyl methacrylate and tetrahydrofurfuryl methacrylate; and an initiator comprising organoborane; wherein the relative Based on the mass of the polymerizable component, the main ingredient contains 60% to 95% by mass of phenoxyethyl methacrylate.

Description

technical field [0001] The present disclosure relates to binary adhesives and structures including cured materials thereof, and in particular to reactive binary adhesives for poorly adhering substrates such as substrates including silicone rubber and the like. Background technique [0002] There is a need for efficient and effective means of adhering poorly adhering substrates, such as silicone rubber, by adhesives. [0003] In the case of adhering such poorly adhesive substrates, surface treatments such as flame treatment, ITRO treatment, corona discharge, plasma treatment, ozone or acid oxidation, or sputter etching are often required. Although primers comprising high surface energy materials can be used to cover the surface of poorly adhering substrates, the surface treatments described above are sometimes required in order for the primer to adhere adequately. In this way, adhesion of poorly adhesive substrates often requires complex and expensive treatments, and even wh...
