CURING PROPERTIES
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.
