A device for storing and applying material, especially dental material, comprises a first zone comprising a first and a second film that define at least one first chamber that receives a first substance, and a pouch separated from the chamber for withdrawing the first substance. The separation between the pouch and the first chamber is provided with a through opening that can be selectively opened. The device further comprises a second zone with a second chamber that is not linked with the first section by way of a through opening that can be selectively opened.

Arizidinosilicones of the general formula (1), wherein R1 represents H, C1-C12 alkyl, C2-C12 alkenyl, C2-C12 alkinyl, C7-C15 alkaryl, C7-C15 aralkyl, C3-C12 cycloalkyl and these groups can be substituted with Cl or F partially, completely or in a mixed manner and/or may contain 0 to 5 heteroatoms selected from O, N, S, R2 represents a group of the selection of R1 and/or R4, and R3 represents SiRl3 or SiR12R4, and wherein R4 represents formula (2), and A represents an (n+1) radical saturated, unsaturated or aromatic, linear, branched or cyclic hydrocarbon group that may contain 0 to 5 heteroatoms selected from O, N, S and that includes 1 to 18 carbon atoms, B is selected from O, S, NR1, D is selected from C(O)O, C(O)NR1, C(O), C(O)C(O), C(O)(CH2)m(C(O), C(S)NR1, CH2, E represents a diradical saturated or unsaturated, linear, branched or cyclic hydrocarbon group that may contain 0 to 5 heteroatoms selected from O, N, S and that includes 0 to 18 carbon atoms, a is 0 or 1, f is an integer from 2 to 1000, n, m is an integer from 1 to 10, and x, y, z each represents 0 or an integer, the sum of which should range between 1 and 10000, with the proviso that, if x is larger 0, y or z is smaller or equal x, preferably smaller or equal 0.05 times x, and especially preferred 0.02 times x. The invention also relates to the use of arizidinosilicones.

Aziridinosilicones and the use thereof

N-alkyl aziridine block copolymers of the general structure (1), wherein R1 represents H, C-Calkyl, C-Calkenyl, C-Calkinyl, C-Caralkyl C-Caralkyl, or C-Ccycloalkyl and these groups can be substituted with C1 or F partially, completely or in a mixed manner and/or may contain 0 to 5 heteroatoms selected from O, N, S; R2 represents a group selected from R1 and/or R4; R3 represents SiR1or SiR1R4, wherein R4 represents a group of the general formula (2), wherein A represents an (n+1) radical saturated, unsaturated or aromatic, linear, branched or cyclic hydrocarbon group that may contain 0 to 5 heteroatoms selected from O, N, S and that comprises 1 to 18 carbon atoms; B is selected from O, S, NR1; D is selected from C(O)O, C(O)NR1, C(O), C(S)NR1, CH; E represents a diradical saturated or unsaturated, linear, branched or cyclic hydrocarbon group that may contain 0 to 5 heteroatoms selected from O, N, S, and that comprises 0 to 18 carbon atoms; Q represents and &#x3b1;, &#x3c9;-radical polyether chain of the general formula (3): &#x2014;[O&#x2014;CH]&#x2014;, wherein g is 2 to 20; h is 1 to 1000; a is 0 or 1; f is an integer from 2 to 1000; n is an integer from 1 to 10; and x, y, z each represents 0 or an integer, the sum of which should range between 1 and 10000, with the proviso that if x is larger 0, y or z is smaller or equal x. There are many uses of these copolymers.

A process of preparing a substrate surface for a subsequent adhesive bond, coating or pouring operation, by applying to the substrate an adhesion promoting composition comprising either:

Process for the preparation of substrate surfaces for adhesive bonding

Curable compositions are described which contain a binder and a high propion of fillers having a mean grain size of &lt;50 .mu.m. The filler proportion of the curable compositions is so high that they cannot be used for the intended purpose because of their high viscosity However, they can be liquefied by exposure to oscillation in the frequency range of 20 Hz to 20 MHz with an amplitude of 1 .mu.m to 5 mm so that they are workable and can be employed for the intended purpose.
