Abstract (en)
[origin: EP2439219A1] Composition comprises: (i) at least one isocyanate groups exhibiting polyurethane polymer; (ii) at least one isocyanate groups exhibiting monomer; and (iii) silicon dioxide, which exhibit functional groups on the surface, which are reactive toward isocyanate groups, where the silicon dioxide is present in the form of particles having an average particle size of = 100 mu m and a specific surface area of >= 100 m 2>/g, and the functional groups of the silicon dioxide, reacts at least partially with isocyanate groups of the isocyanate monomer. An independent claim is also included for reducing the content of isocyanate monomers in the composition containing at least one polyurethane polymer having isocyanate groups, and at least one monomer exhibiting isocyanate group, comprising (a) providing a composition having at least one isocyanate polyurethane polymer and at least one monomer having isocyanate groups, and (b) combining the composition with the silicon dioxide exhibiting functional groups on its surface, which are reactive toward isocyanate groups.
