UV5140 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 of ultraviolet radiation of 20mw/cm2 produced by a high-pressure mercury lamp:

Properties Reference
Surface drying time (1mm) 3-5 seconds
Deep curing time (1mm) 15-20 seconds
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 600mj/cm2:

Properties Test method Reference
Hardness Shore D 80-85
Operating temperature range -40~130℃ Customers conduct self-test with workpieces
