PREPOLYMER MIXTURE FOR A PU FLOORING
The invention relates to a method for producing a 1C polyurethane system adapted for creating an elastic floor layer (129) at temperatures at or below 10°C. The method comprises creating (602) an initial mixture (900). The initial mixture comprises a mixture of MDI monomers, polymeric MDI and a polyol component. The MDI monomer mixture comprises 2,2' MDI, 2,4' MDI and 4,4' MDI, wherein at least 3.8% by weight of the initial mixture consist of the 2,2' MDI. The polyol component comprises EO-end-capped polypropylene glycol and a further polyol. The method further comprises reacting (604) the initial mixture into a prepolymer mixture comprising a prepolymer being the reaction product of the MDI monomers, the polymeric MDI and the polyol component.
