Abstract:
Filler for plastics formulations based on polyurethane, obtained by reaction of the following components (A) to (E):(A) 15 to 35 wt. % of one or more radiation-curing (meth)acrylate-based compounds with OH numbers of 40 to 700 mg KOH/g (B) 15 to 40 wt. % of one or more polyols with a molecular weight of 500 to 6,000 g/mol (C) 0 to 15 wt. % of one or more polyols with a molecular weight of less than 500 g/mol (D) 1 to 10 wt. % of at least one compound which is mono- and/or difunctional in the sense of the isocyanate reaction, which additionally contains anionic groups or functional groups which can be converted into anionic groups (E) 24 to 69 wt. % of one or more polyisocyanates, and subsequent crosslinking the resulting product from (A) to (E) with component (F)(F) 0.5 to 10 wt. % relative to the total weight of components (A) to (E), of a mixture of at least one diamine with a polyamine of functionality greater than 2, at least 30 wt. % of component (F) comprising polyamine of functionality greater than 2.
