The invention relates to an aqueous dental single-component primer composition as well as a kit with this primer composition and a composite. The primer composition according to the present invention is self-etching and self-undercoating. It comprises a polymerizable (meth)acrylate or (meth)acrylamide monomer with (i) at least one acidic group such as for example a phosphoric acid group and with (ii) at least one hydrophilic group such as for example a terminal hydroxy group or two polymerizable (meth)acrylate or (meth)acrylamide monomers, wherein one thereof comprises (i) at least one acidic group and one thereof comprises (ii) at least one hydrophilic group. In addition, at least one of the polymerizable (meth)acrylate or methylacrylamide monomers comprises (i) a polyfunctionality, preferably an at least threefold polyfunctionality, particularly preferably a 3-, 4-, 5-, 6-, 7-, 8-, 9- or 10-fold polyfunctionality and/or (ii), or a further polymerizable (meth)acrylate or methylacrylamide monomer (iii) with a polyfunctionality, preferably an at least three-fold polyfunctionality, particularly preferably a 3-, 4-, 5-, 6-, 7-, 8-, 9- or 10-fold polyfunctionality is contained. This polyfunctionality inheres in the capability to polymerize. In particularly, at least three, preferably terminal, (meth)acrylate, (meth)acrylamide and/or allyl groups are present. Furthermore, this primer composition is characterized by the absence of a photoinitiator, a polymerization catalyst, in particularly a polymerization catalyst on the basis of vanadium as well as by the absence of an organic solvent.

The present disclosure relates to a mixer having a mixer housing which encloses a mixing chamber, an input part which can be connected to the mixer housing and has at least two input openings for the components to be mixed, and a mixing element, at least some sections of which extend into the mixing chamber, wherein each of the input openings is flow-connected to the mixing chamber via at least one input duct, wherein there is also in the input part at least one compensation duct which connects the input openings to each other, and/or at least one holding chamber is provided in the mixing element.

Mixer having compensation channel and/or reservoir chamber

The disclosure relates to a specifically static mixer for mixing two components, with a housing, in which a mixing element is accommodated, and an input part with a first intake and a diametrically opposite second intake, wherein, within the input part, a first channel is formed between the first intake and the mixing chamber and a second channel is formed between the second intake and the mixing chamber. The first channel extends radially inward from the first intake and opens into a central opening in the cover. The second channel has two partial channels as storage chambers not leading into the mixing chamber, and two intake sections located radially within the storage chambers and leading into the mixing chamber. The intake sections branch off the respective storage chambers, extend inward in the opposite direction to the first channel and open into the central opening in the cover.

Mixer and method for mixing two components

The present disclosure relates to a mixer for mixing pasty components, comprising a mixing case extending along a longitudinal axis and having at least one inlet, preferably two inlets, and an outlet, and comprising at least one mixing element received in the mixing case, which defines a plurality of chambers together with the mixing case, said chambers being arranged successively and/or adjacently along a flow path from the inlets to the outlet. The chambers are defined by transverse walls, each extending perpendicularly to the longitudinal axis, and four side walls that each extend parallel to the longitudinal axis, and adjacent chambers are interconnected by a flow by means of through-openings provided in the side walls, the mixing element comprising two strips forming side walls, which are connected by a web that forms other side walls and is perpendicularly arranged in relation to the strips, a first group of chambers having first through-openings arranged in the web, which extend up to a strip, and a second group of chambers comprising second through-openings positioned at a distance to at least one strip in the web.

Mixer

The present disclosure relates to an application system with a cartridge having at least one container with a respective outlet, and a closure element that can sealingly close the outlet of the at least one container when the cartridge is in the delivery state. When in the storage state, the cartridge sealingly closes the closure element. When the cartridge is in the state of use, the closure element can be removed therefrom and an accessory can be connected to the outlet of the at least one container. According to the invention, the cartridge or the closure element comprises, in the delivery state, a connecting element which cannot be removed without being damaged, and the cartridge or the closure element, in the storage state, is connected via a connecting element that cannot be removed without being damaged, to a closure element or the cartridge.

Application system

An application system is presented having a cartridge, at least one first accessory part, for example a stopper, and at least one second accessory part, for example a static or dynamic mixer. The cartridge has at least one container with an outlet opening and at least one outlet connected to the container via the outlet opening on the end face of the cartridge, wherein the at least one outlet can be connected to the at least one first accessory part and the at least one second accessory part such that a seal is produced between the outlet and the respective accessory part. At least one separate seal plane is provided for each accessory part.

Medical cartridge

The invention relates to a container () for storing and discharging at least one component with at least one chamber (), which is sealed on a first side by a plug (), and with one applicator () attached on the first side. A flow connection between the at least one chamber () and the side of the applicator () facing away from the at least one chamber () is opened by a relative rotational movement of the applicator () to the container () and a subsequent axial relative movement of the plug () to the container () and the applicator (), in particular due to pressure of the at least one component on the plug (). Furthermore, the invention relates to a method for storing and discharging at least one component.

Container for storing and dispensing at least one component and method therefor

The invention relates to a polymerizable dental material containing a catalyst paste (A) and a base paste (B), wherein the catalyst paste (A) contains at least one organic peroxygen compound, at least one radically polymerizable organic (meth)acrylic monomer and at least one filler, and wherein the base paste (B) contains at least one radically polymerizable organic (meth)acrylic monomer, an amine as co-initiator of the radical polymerization, at least one filler and at least one salt-like, water-soluble, powdery reduction agent dispersed therein, wherein the catalyst paste (A) and/or the base paste (B) contains at least one phase transfer catalyst that is selected from the group consisting of the ammonium, phosphonium and/or sulfonium salts that contain an inorganic or organic anion, provided that the phase transfer catalyst&#x2014;in the event of organic anions&#x2014;contains only those having 1-4 carbon atoms, and that anions of sulfinic acids are precluded.
