Definitions
- the present invention relates to cold-stable NCO-containing prepolymers, obtainable from the reaction of an isocyanate-reactive component comprising polyether carbonate polyols with an isocyanate component comprising methylenediphenyl diisocyanate (MDI) with high levels of 4,4'-MDI, processes for their preparation and their use in 1- and 2-component systems for foams, elastomers, adhesives and sealants.
- an isocyanate-reactive component comprising polyether carbonate polyols
- an isocyanate component comprising methylenediphenyl diisocyanate (MDI) with high levels of 4,4'-MDI
- NCO-containing prepolymers are used in many technical fields, in particular for the production of foams and elastomers, for bonding and coating substrates and in sealants. Both moisture-curing 1-component systems and 2-component systems are used, with polyols and / or polyamines often being used as reactants for the NCO-containing prepolymers.
- 4,4‘-MDI is a solid at room temperature that tends to form irreversible dimers. In this case, irreversible means that the dimers do not split under the processing conditions and that the product properties deteriorate.
- a similar behavior is also observed with prepolymers based on 4,4‘-MDI. This is why these NCO-containing prepolymers have to be temperature-controlled during storage and cannot be used without temperature control, e.g. at low outside temperatures on construction sites.
- NCO-containing prepolymers with polyether carbonate polyols as structural components are described, for example, in EP 2 566 906 B1 and EP 2 691 434 B1.
