Expose the sample to UVA light (intensity approximately 100 mW/cm2) for 10 s. 4.3 USE OF ACTIVATOR For special reasons (faster and/or complete curing, inactive surfaces - Z
19、n, Cr, Ni, Cd, plastics, ceramic) activators may be required (see also para 2, 3.6.1). For details of use (kind of application, open time, reactivity etc.) see activator specification. Generally the strength after final curing on standard surfaces is lower when an activator is used (see para 3.6.1).
