    Abstract: The invention relates to a kit of parts comprising a Base Paste (B) and a Catalyst Paste (C), Base Paste (B) comprising a cationically hardenable component, Catalyst Paste (C) comprising a starter component suitable to contribute to the hardening of the cationically hardenable compound, the composition obtained when combining the compositions of Base Paste (B) and Catalyst Paste (C) comprising in addition a porous water-adsorbing component and water, the porous water-adsorbing component being selected from molecular sieves, zeolites, silica gel and mixtures thereof, wherein either the porous water-adsorbing component is present in Base Paste (B) and the water is present in Catalyst Paste (C), or the water-adsorbing component is present in Catalyst Paste (C) and the water is present in Base Paste (B). The invention also relates to a dental retraction composition obtainable by mixing Base Paste (B) and Catalyst Paste (C) and to a process of taking a dental impression and/or conducting a dental retraction using the kit of parts.

    IPC: C08L83/08 ,  B33Y70/00 ,  B29C64/129

    Abstract: The invention relates to a radiation-curable silicone composition for additive-manufacturing technology comprising mercapto-functional polyorganosiloxane(s) as Component A, organosiloxane(s) with at least two aliphatic unsaturated carbon-carbon moieties as Component B, photo-initiator(s) as Component C for initiating a curing reaction between Component A and Component B, dye(s) as Component D dissolved in mercapto-functional polyorganosiloxane(s) as Component E, the mercapto-functional polyorganosiloxane(s) having a fraction of (mercaptoalkyl)methylsiloxane units of at least 50 mol %, wherein Component D is dissolved in Component E before Component D is combined with the other components of the radiation-curable silicone composition. The invention also relates to a process of producing a radiation-curable composition wherein the process comprises the steps of providing a solution of dye(s) in a composition comprising mercapto-functional polyorganosiloxane(s) having a fraction of (mercaptoalkyl)methylsiloxane units of at least 50 mol %, combining the solution containing the dye(s) dissolved in the mercapto-functional polyorganosiloxane(s) with mercapto-functional polyorganosiloxane(s), organosiloxane(s) with at least two aliphatic unsaturated carbon-carbon moieties, photo-initiator(s) for initiating a curing reaction between Component A and Component B, optionally filler(s), stabilizer(s) and additive(s).

    Abstract: The present invention relates to a kit of parts comprising Paste (A), Paste (B) and Paste (C), the pastes being characterized as follows: Paste (A) comprising at least one polyorganosiloxane with at least two olefinically unsaturated groups, and at least one organohydrogenpolysiloxane, at least one alkylsiloxane having at least one carbinol, silanol, alkoxy, carboxyl or amino group, optionally filler(s) and optionally additive(s); Paste (B) comprising at least one polyorganosiloxane optionally with olefinically unsaturated groups, at least one addition cure catalyst, optionally at least one alkylsiloxane having at least one carbinol, silanol, alkoxy, carboxyl or amino group, optionally filler(s) and optionally additive(s) Paste (C) comprising a softener, a condensation cure catalyst, optionally filler(s), and optionally additive(s) optionally at least one polyorganosiloxane optionally with olefinically unsaturated groups. The invention is also directed to a system for storing and delivering Paste (A), Paste (B) and Paste (C), the system comprising three compartments for storing the respective pastes, means for delivering the respective pastes to an outlet orifice and an interface for receiving a mixing tip. The kit of parts or the system is in particular useful for conducting a dental retraction and dental impression process.
