  • Composition for one-component polyurethane foams having low free monomeric MDI content
    Patent number: 9796808
    Abstract: A one component precursor for the polymeric foam (OCF) composition comprising a very low amount of free monomeric MDI. The present OCF composition may be obtained without any free MDI removal step, and without the addition of extra solvent to compensate for the substantially lower amount of free MDI, compared with traditional compositions. The present composition comprises a source of free NCO of functionality of at least 2.6, a tri- or higher functional alcohol, all polyols being characterized by a rather low molecular weight and at least a specific mono-functional alcohol as well as an isocyanate end-capped prepolymer of toluene diisocyanate (=end capped TDI). The OCF composition is suitable for being dispensed from a pressurized can with a blowing agent.
