A container () is provided for single- or multi-component molding materials. The container has a container body () having a constant outer contour in a longitudinal extent of the container (), a piston () movable in the longitudinal direction, and a cover () having an outlet opening (). A volume for a molding material is defined between the piston () and the cover (), the volume being variable in the direction of the longitudinal extent of the container (). The container distinguishes itself in that the container body () is rotatable relative to the outlet opening (), and the piston () thereby pushes out the content of the container ().

Multi-component mixing system having a rotatable container and container therefor

Single-use cartridges for the storing and dispensing of dental two-component impression materials have a closable external chamber with a cylinder-shaped external wall, a cylindrical closable internal chamber that is arranged coaxially or eccentric therein, a mixing element including housing and mobile mixer that is to be mounted separately or connected firmly to the external chamber at its inlet end. Either the internal cylindrical chamber is arranged such that it can be rotated and forms the drive shaft for the mobile mixer part of the mixing element, or the drive shaft extends parallel to the central axis through the internal cylindrical chamber or forms the central axis. The content of the chambers can be dispensed by means of conveying means whose axial thrust motions can be controlled independent of each other.

Single-use cartridges for the storing and dispensing of dental two-component impression materials

A cylindrical cartridge for receiving a pasty material, having a sealing piston and a spreading piston insertable into the sealing piston which, sealing piston and spreading piston, when inserted into said cartridge, cooperate to vent air from and seal said cartridge.

Sealing piston for cartridges with de-aeration and barrier properties

Two-component preparation on the basis of silane functionalized polyether derivatives, which cures into an elastomer product after the mixing of a base component containing silane functionalized polyether derivate with a catalyst component containing organic or inorganic acid, wherein the base component comprises an antiacid.

Two-component dental molding composition having at least one anti-acid acting compound

Among other things, a silicone composition curing by condensation at room temperature is prepared from a base dough containing filler and polyorganosiloxane having hydroxy groups, as well as from an activator component containing crosslinker and a catalyst of an organometallic compound, which is characterized in that the activator component additionally contains a polyether having at most one alkoxysilyl group and/or a polyaddition product based on polyether and having at most one alkoxysilyl group.

Silicone composition curing at room temperature and the use thereof

A silicone composition curing at room temperature by condensation, which is suitable especially as a dental molding composition. The silicone composition consists of the a) base paste containing a filler and polyorganosiloxane having hydroxy groups, b) and the activator component containing in addition to crosslinking agent and catalyst also a polyaddition product with alkoxysilyl groups in the molecule. The base paste and activator component can be mixed uniformly together and can be offered with special advantage in double cartridges.
