| titleOfInvention | Adhesion Promoter for Monomer-Free Reactive Polyurethanes |
| abstract | Polyurethane compositions are prepared in a two-step process. In the first step, a diol component with a molecular weight of less than 2000 is reacted with monomeric diisocyanate with a molecular weight of less than 500 and unreacted monomeric diisocyanate is removed from this reaction mixture. In the second step, the high molecular weight diisocyanate obtained is reacted with a polyol to prepare a reactive prepolymer having isocyanate end groups. The addition of polyisocyanates that are mobile and have a vapor pressure substantially lower than diphenylmethane diisocyanate improves the additional behavior of the polyurethane composition of the present invention. Reactive polyurethane compositions of this type are suitable for use as binders for reactive one or two component adhesives / sealing agents, which may optionally contain a solvent. These compositions are also suitable for producing reactive hot melt adhesives when suitable polyols are selected. A substantial advantage of these compositions compared to known polyurethane compositions is the significantly lower proportion of monomeric diisocyanates having a molecular weight of less than 500.n n n Polyurethane, Polyisocyanate |
