    摘要: A pasty composition for the room temperature crosslinking and curing of a vulcanizable organopolysiloxane, comprising a crosslinking agent for an organopolysiloxane, a curing catalyst therefor, and about 3-40% by weight of the total amount of the pasty composition of active hydrophilic silica as a thickener. The pasty composition may additionally contain up to about 40% by weight of at least one inactive filler. Advantageously, the organopolysiloxane is in one tube and the pasty composition is in another; lengths of material are squeezed out in easily ascertained proportions and are mixed in the presence of water, e.g. water vapor in the atmosphere, the mixture setting to a silicone rubber.

    摘要: The invention includes formulated dental filling materials comprising a polymerizable organic plastics material containing inorganic fillers, which filling material comprises at least two pastes in intimate admixture with one another in a paste/paste system in which hardening is initiated by means of a peroxidic initiator and an accelerator, wherein said at least two pastes contain different inorganic fillers with different chemical constitutions such that one of said at least two pastes contains filler with a substantially higher proportion of elements with high atomic number than does the other of said at least two pastes. Also included in the invention is a dental filling pack containing said formulated dental filling materials as well as a method for their use.
