Problems solved by technology

However, these systems have disadvantages, especially for industrial applications with high production volumes; because water cannot be removed from the sprayed coating quickly enough due to the large coating thickness
Another disadvantage of these conventional methods of sound attenuation is that these materials are used for the single purpose of sound attenuation

Abstract

The invention relates to heat-curing preparations, containing (a) a triglyceride fraction, the fatty acid distribution of which has a portion of at least 5 wt%, in particular of at least 60 wt%, of one or more omega-3 fatty acids and / or one or more omega-6 fatty acids, (b) at least one vulcanizing agent selected from the group comprising (b1) sulfur, (b2) peroxidic vulcanizing agents, (b3) quinones and / or quinone dioximes, and / or (b4) dinitrosobenzenes, and (c) at least one inorganic filler.

Description

technical field [0001] The present application relates to thermally curable formulations based on triglyceride moieties containing omega-3 fatty acids and / or omega-3 fatty acids, to processes for the preparation of said formulations, and also to said formulations as acoustic damping adhesives, sealants or Use of the coating composition. Background technique [0002] Metal sheets with very thin walls are often used in the production of automobiles, machines and devices to reduce their weight. Mechanically moving parts or running motors inevitably cause these thin-walled metal plates to vibrate at frequencies generally within the range of human hearing. These vibrations are propagated through the entire vehicle, machine or installation in the form of structure-borne sound, which can be released into the air at a distance as disturbing noise. Therefore, in order to reduce sound emission and eliminate structure-borne noise, the thin-walled metal sheets used, especially in the ...
