Abstract:
Process for preparing 2-alkyne 1-acetals of the general formula I, where the radicals have the following meanings: R1 is hydrogen, C1-C20-alkyl, C2-C20-alkenyl, C2-C20-alkynyl, C3-C12-cycloalkyl, C4-C20-cycloalkylalkyl, C4-C10-aryl, with these radicals optionally being able to be substituted by hydroxy, halogen, C1-C6-alkoxy, (C1-C6-alkoxy)carbonyl, carboxyl or nitrile groups, R2 is C1-C6-alkyl or a radical of the general formula II where R1 is as defined above, R3 has the same meaning as the radical R2, by electrochemically oxidizing a compound of the general formula III where the radical R1 has the same meaning as in the general formula I, in the presence of C1-C6-alkyl alcohols (alcohol A) or as such.

Abstract:
A process for producing multi-layer coatings comprising a waterborne primer-surfacer layer and a topcoat applied thereto on substrates, in which a waterborne primer-surfacer layer is applied from a waterborne primer-surfacer to substrates and baked and then a topcoat is applied, wherein the waterborne primer-surfacer has a binder solids content with a hydroxyl number of 100 to 250 mg KOH/g and contains free or blocked polyisocyanate as a curing agent (crosslinking agent) for the hydroxy-functional binder(s) in a molar ratio of OH/NCO of more than 2:1 to 5:1, and wherein, after it has been applied and before baking, the waterborne primer-surfacer layer is allowed to evaporate for 30 to 300 seconds at 15 to 40° C.
Abstract:
A method for producing woven airbags, especially at least partially multi-layered airbags, includes the following steps: the warp threads are prepared in a warping room, warp threads which are suitable as marker threads for machine-readable markings being already placed in the warp; the airbag material is woven, weft threads which are suitable as marker threads for machine-readable markings being interlaced over at least part of the width of the cloth; and the airbag is cut out of the airbag material using a cutting device which is guided by the interlaced machine-readable markings.
Abstract:
A process for the high-speed rotary application of a liquid coating agent onto a substrate, wherein the process comprises the steps: (a) direct supply of at least two liquid components in a specified quantity ratio which determines the qualitative and quantitative composition of the coating agent to at least one high-speed rotary atomizer or preparation of a premix from at least two liquid components in a specified quantity ratio which determines the qualitative and quantitative composition of the coating agent and supply of the premix to at least one high-speed rotary atomizer, (b) high-speed rotary atomization of the components directly supplied in step (a) or of the premix supplied in step (a) to the at least one high-speed rotary atomizer and (c) application of the material atomized in step (b) onto a substrate, wherein at least one of the components used in step (a) differs from at least one further component used in step (a) with regard to density by 0.05 to 2 g/cm3 and/or with regard to flow time (DIN EN ISO 2431, DIN 4 cup, 20° C.) by 15 to 150 seconds.
