Silane-terminated PUs offer high flexibility for adhesives and sealants

摘要

Silane-terminated polyurethanes (SPUR) are becoming increasingly common in the adhesives and sealants sector. Users are taking up SPUR materials because, "These silylated PUs, we think, have a very good set of properties, combining the advantages of silicone-curing technology with the mechanical advantages of a PU backbone", said Thorsten Adebahr, commercial director of Hanse Chemie AG, in an interview at the European Coatings Show in Nuremberg in April.
