Fatty acid monoesters with at least 12 carbon atoms can replace a considerable portion of the conventional softeners based on phthalic acid esters, alkylsulphonic acid esters of phenol or other prior art softeners in plastisol compositions. The methyl and/or ethyl esters of fatty acids from renewable fats and oils, such as tall oil fatty acids, rapeseed oil fatty acids, linseed oil fatty acids or safflower oil fatty acids are preferably used for these secondary softeners. Preferably these plastisols are used as adhesives, sealants or coatings in the automotive industry.
Les monoesters d'acides gras comportant au moins 12 atomes de carbone peuvent remplacer une proportion considérable de plastifiants classiques à base d'esters d'acide phtalique, d'esters d'acide alkylsulfonique du phénol ou d'autres plastifiants de la technique antérieure, dans les compositions de plastisol. Les esters de méthyle et/ou d'éthyle d'acides gras provenant de graisses et huiles renouvelables, telles que les acides gras de tallöl, les acides gras d'huile de colza, les acides gras d'huile de lin ou les acides gras d'huile de carthame sont utilisés de préférence pour ces plastifiants secondaires. Ces plastisols sont utilisés de préférence sous forme d'adhésifs, de matériaux d'étanchéité ou de revêtements dans la construction automobile.
