Publication number: 20200095367Abstract: Low-viscosity urethane methacrylate compounds are used as a backbone resin in reactive resins. In particular, the compounds are for lowering the viscosity of reactive resins containing such mixtures and thus the extrusion forces of reactive resin components produced therefrom and also for increasing the performance of reactive resins and reactive resin components produced therefrom containing such compounds. Furthermore, said compounds and their reactive resin components are used for construction purposes, in particular for chemical fastening.Type: ApplicationFiled: June 19, 2018Publication date: March 26, 2020Applicant: Hilti AktiengesellschaftInventors: Georg Nickerl, Beate Gnass, Natja Park, Jens Bunzen, Klaus Schaefers, Ralf Neuerburg, Rainer Strobel-Schmidt, Gerald Gaefke
