CURING PROPERTIES

UV5128 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 ultraviolet radiation conditions of 220mw/cm² from a 395nm wavelength LED surface light source:

Properties Reference
Tack free time (1mm) 5-10 S
Deep curing time (1mm) 5-10 S
Full cure energy (1mm) 2500 mj / cm²

*Recommend to use with FUV-100 Curing Oven or CUV-350 Curing Conveyor.
