More Information
Summary:The invention relates to a low-monomer, cross-linkable, 1-component or 2-component polyurethane adhesive, comprising a polyurethane prepolymer having NCO groups having a molecular weight of less than 5000 g/mol and common additives and auxiliary substances, having a content of monomeric diisocyanates of less than 0.5 wt %, wherein, in relation to the PU prepolymer, 0.5 to 30 wt % esters of monocarboxylic or dicarboxylic acids having 2 to 24 carbon atoms is present.
