Abstract: The invention relates to a coating compound for automobile construction, comprising a filler, preferably an aluminum silicate-based filler, which reduces, more particularly prevents, bubbling on transition from the wet state to the dry state.

Abstract: A static mixing device (1), containing at least one first mixing element (A) which contains a plurality of particularly parallel channels (2), which are orthogonal in relation to the main direction of flow (H), on a front side, wherein the channels (2) are not connected to each other but comprise through-flow openings (3) in the main direction of flow (H); further comprising a second mixing element (B) which enters into contact with the first mixing element (A) and which comprises a plurality of particularly parallel channels (2), which are orthogonal in relation to the main direction of flow (H), wherein the channels (2) are interconnected, wherein openings are more particularly provided in the side walls of the channels (2), enabling a medium (M) to pass therethrough in the main direction of flow (H). A plurality of more particularly parallel channels (2), which are not connected to each other, are arranged in an orthogonal manner in relation to the main direction of flow (H) on a rear side (R) thereof.
