ABSTRACT:
The present invention provides a two-component composition for use to form a solvent-free fixing material suitable for use in dentistry, which fixing material is liquid at room temperature and has a viscosity in the range of from 5,000 to 100,000 cP, said compositions having: a first component comprising at least one organic polyisocyanate with aliphatically and/or cycloaliphatically bonded isocyanate groups; and a second component comprising (a) at least one polyhydroxy compound having a molecular weight in the range of from 200 to 20,000, being substantially free of ether groups, and having at least 2 aliphatically bonded OH groups and (b) from 1 to 60% by weight, relative to the total mixture, of monohydric and/or polyhydric alcohols with a molecular weight below 200 and/or from 0 to 40% by weight, relative to the total mixture, of oligomeric polyesters containing at least 2 OH groups or ester-diols, with an average molecular weight of from 100 to 500, the first and second components of the mixture being present in amounts corresponding to a NCO/OH ratio of from 0.8:1 1.2:1.
