PROCEDURE
 Mixing it on the glass plate with an agate or plastic spatula.
 Environment of mixing: using it at the temperature of 231℃ and at the relative humidity of
50+10% recommended. If using it at higher temperature, its curing procedure will be fastened
and its working time will be decreased. If using it at warmer area, please use a cooler glass
plate.
 The proportion of powder to liquid is 1.5g : o.5 ml（0.85g）.
 The proportion of powder to liquid for test is 1.5g : o.5 ml（0.85g）. Test at the temperature of
231℃ and at the relative humidity of 5010% in accordance with ISO9917-1:2007.
 Operation procedure:
When mixing, first divide the weighed powder into three heaps (i.e. big, middle, small), then
put the first heap of powder into proportional liquid and mix it evenly for about 10 seconds,
put the second heap of powder into proportional liquid and mix it evenly for about 15 seconds
and put the last heap of powder into proportional liquid and mix it thoroughly.
 Mixing time: accomplish the whole mixing procedure within 60 seconds.
 Working time: the whole material mixing procedure should accomplish in 90 seconds
 In a case of deep pulp: cover the dentine most close to the pulp with eugenol cement so as to
avoid acid irritation to the pulp.
 Post treatment: after the filling process, remove the excess material by using a wet cotton and
trim it after 24h when its curing.
 The product can be stored in a dry place of 10 ~ 23℃for best performance.
