The invention relates to a kit of parts comprising part A and part B, part A comprising a polymerizable component having an acid group in the molecule, an initiator, part B comprising an activator, and a film former with a molecular weight of at least 1000.

The invention also relates to a composition obtainable by mixing the components contained in the kit of parts and to a process for producing the kit of parts comprising the steps of bringing the components contained in part B of the kit in contact with a surface, drying the surface to form a film.

The present invention relates apparatus for holding material to be dispensed in a surgical setting, and in particular that: (a) allows for small portions of material to be dispensed efficiently, (b) resists evaporation of volatile agents in the material being dispensed, (c) reduces exposure of the material to light and actinic radiation during intermittent use, and (d) supports autoclaving in order to fulfill sterilization standards in surgical setting.

A container (100) for producing a self-curing or dual-curing dental synthetic material composition (200), which container includes a deformable wall (101), having a first synthetic material component (103-1); and a second synthetic material component (103-2) for curing the synthetic material composition (200) or starting a curing reaction.
