* - The curing time is the time, measured till the achievement of the maximum temperature of composite with the layer thickness of 2 cm ant the rate Aksa 16 / fillers = 20 / 100. We take 4 % of curing agent (on resin).
*** - The open time is the time, measured from the mixing of the curing agent (4 % on resin) into the composite mixture to the beginning of viscosity increase, at the layer thickness of 2 cm and the rate Aksa 16 / fillers = 20 / 100. After the achieved open time the mass starts to drag during agitation.
** - The curing time is the time, measured till the achievement of the maximum temperature of composite with the layer thickness of 2 cm and the rate Aksa N / ATH = 20 / 100. Approximately 0,5 % of curing agent. The recipe (and curing) depends on the type of the applied fillers, too.
