Abstract
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.
Claims14
A plastisol composition comprising 5 to 60 weight % of at least one pulverulent organic polymer, 5 to 65 weight % of at least one plasticizer, 1 to 30 weight % pulverulent saccharide selected from the group consisting of monosaccharides, disaccharides and oligosaccharides, and 0.01 to 40 weight % of at least one reactive additive selected from the group consisting of di- and polyisocyanates, blocked di- and polyisocyanates, microencapsulated di- and polyisocyanates, amino-functional additives, hydroxy-functional additives, epoxy resins, condensation products of epoxy resins and polyaminoamides and/or di- or polyamines, dicarboxylic acids, di- and tricarboxylic acid anhydrides, β-dicarbonyl compounds, metal chelates of β-dicarbonyl compounds, peroxides and mixtures thereof.
