Publication number: 20160040050Abstract: A polyurethane-based composition is disclosed which includes a polyurethane prepolymer, a solvent, a plasticizer and a curing agent, wherein the curing agent contains a mononuclear aromatic polyamine, and is present in an amount such that the molar ratio of all amine functions in the polyamine to all isocyanate functions in the composition is at least 0.7 to 1. Such polyurethane-based compositions have proven effective for example as adhesives and fillers in the repair of elastic substrates since they can be processed quickly and readily even at low temperatures. Methods are also disclosed for bonding or repairing elastic substrates that include corresponding polyurethane-based compositions, and to use of the composition for bonding and repairing elastic substrates.Type: ApplicationFiled: March 12, 2014Publication date: February 11, 2016Applicant: Sika Technology AGInventors: Hector MUÑOZ, Pedro GALLEGOS, Thomas HAACK
