The addition of pulverulent monosaccharides, disaccharides or oligosaccharides to plastisols based on pulverulent organic polymers and plasticizers results in plastisols with good adhesion properties on a large number of substrates employed in automobile construction. These plastisols are distinguished by good adhesion properties and a high resistance to ageing, and can be employed in automobile construction both in shell construction and in the lacquering line and in the trim shop for adhesive, sealing and coating tasks.
