Abstract
Monoesters of fatty acids containing at least 12 carbon atoms may replace a considerable percentage of conventional plasticizers based on phthalic acid esters, alkyl sulfonic acid esters of phenol or other known plasticizers in plastisol compositions. The methyl and/or ethyl esters of fatty acids of 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 plasticizers. These plastisols are preferably used as adhesives, sealing materials or coatings in automobile construction.
