    摘要: The present invention is directed to photoinitiated cationic epoxy compositions, which show a delayed onset of cure resulting in controllable “open times” for the end user consumer. These compositions are activated by exposure to electromagnetic radiation, such as UV radiation with a wavelength In the range of 254-405 nm, but show a commercially meaningful “open time” and then cure even in shaded zones to achieve a desired final adhesive strength.
