摘要：The invention relates to a two-component addition-cured silicon impressioncompound, comprising the following when both components are mixed: (a) between 1and 35 wt. % of at least one organopolysiloxane comprising at least two unsaturatedgroups in the molecule; (b) between 1 and 10 wt % of at least one

organohydrogenpolysiloxane comprising at least two SiH groups in the molecule; (c)between 0.00005 and 0.05 wt. % of at least one platinum catalyst, calculated as

elementary platinum; (d) between 4 and 10 wt. % of at least one liquid paraffin or at leastone white mineral oil, or of a mixture of at least one liquid paraffin and at least one whitemineral oil; (e) between 50 and 90 wt. % of at least one filler, each respective percentagerelating to the total weight of the silicon impression compound. According to theinvention, one of the components before being mixed with the other component has aBrookfield viscosity ranging between 800 and 2000 Pa*s. The invention is characterised inthat the silicon impression compound, when mixed, has a consistency stipulated by ISO4823 of less than or equal to 35 mm.
