Addition cross-linking two-component silicone materials Addition cross-linking two-component silicone materials on polysiloxane base, especially for the use in dental medicine and dental technique contain, so as to obtain a product with a high Shore D hardness and a high modulus of elasticity, organopolysiloxanes with two vinyl groups in the molecule, organohydropolysiloxanes with two or more SiH groups in the molecule, catalysts for the acceleration of the hydrosilation reaction, reinforcing material, non-reinforcing material, eventually dyestuff, eventually moisture binder, eventually organopolysiloxanes with more than two vinyl groups in the molecule, eventually inhibitors for the adjustment of reactivity, eventually vinyl group containing solid or liquid MQ-resins, eventually compounds made of organopolysiloxanes and reinforcing filling material, eventually tensides, emulsifying agents and stabilizing agents, eventually radio-opaque substances and eventually H.sub.2 absorbing or adsorbing substances and substances which eliminate or reduce the H.sub.2 development.
