A method of determining a curing behavior of an electromagnetic radiation curing adhesive and a curing test device

摘要

The invention relates to a method for determining a curing behavior of an electromagnetic radiation curing adhesive (4), wherein in a first determination phase (20) with a radiation having a first wavelength (15) in the electromagnetic spectral range is irradiated to the adhesive (4) and a first time period (35) is determined until a value of a parameter (29, 32) of the adhesive (4) which at least characterizes a degree of curing is reached, and in which a second determination phase (21) with a radiation different from the first determination phase (20) with a second wavelength (16) different from the first wavelength (15) in the electromagnetic spectral range is irradiated onto the adhesive (4) and a second period of time (36) until reaching the value of the parameter (30, 33) of the adhesive at least characterizing the degree of cure (4), wherein the durations (35, 36) are compared w ground and that wavelength (15, 16) is set as the reference wavelength (38) for a curing process in which a parameter characterizing the curing of the adhesive (4) is greatest.
