UV5144 will cure under sufficient UV irradiation conditions. The curing speed and depth depend on the light intensity, spectral distribution of the light source, irradiation time and the light transmittance of the adhered material. The following data are measured under the condition that a 395nm wavelength LED surface light source generates 400mw/cm2 ultraviolet radiation:

Properties Reference
Fixed time (S) 10S
Tack free time (1mm) 5S
Deep curing time (1mm) 10S
