Curing will occur under sufficient ultraviolet irradiation. 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 of ultraviolet radiation of 20mw/cm² produced by a high-pressure mercury lamp:

Properties Reference
Tack free time (1mm) 10 s
Anaerobic positioning time 11 s
Deep curing time (1mm) 20 s
Full cure energy (1mm) 600 mJ/cm²

*Recommended Curing Equipment: CUV-1800M Mercury UV Curing System


The following data are measured after curing with a high-pressure mercury lamp source with a cumulative energy of 600 mj/cm²
