Abstract (en)
[origin: WO2013167671A2] The invention relates to a method for producing a two-component polyurethane composition comprising at least one additive soluble in polar solvents, in particular a biocide, comprising the following steps: a) providing at least one polyol; b) adding at least one solution of the polar solvent comprising at least one additive soluble in polar solvents, in particular a biocide, and at least one carrier material for the additive to the polyol from step a); and c) providing, in accordance with the requirements, at least one isocyanate for adding to the mixture from step b). Said method has the advantage that additives can be incorporated into a two-component polyurethane composition without agglomerating or precipitating, without side reactions, and without an additional drying step.
