Abstract (en)
[origin: WO2009033874A1] The invention relates to a method for producing a roller shell or roller covering (1) of a roller from a PPDI-based polyurethane. To avoid stress cracks, the intention is to overcome the inadequacy in green strength as quickly as possible by the hardener that is added to the polyurethane bringing the pot time down to 5 to 60 s. The invention also relates to a PPDI polyurethane for producing a roller shell or roller covering (1) of a roller formed by mixing a PPDI prepolymer with a hardener, in particular for carrying out the method, wherein it is essential that 60 to 99% by weight of the hardener is 1,4-butane diol, at most 40% by weight is diamine and at most 1% by weight is a catalyst.
