Calcined Neuburg Siliceous Earth in adhesives with high strength based on silane terminated polyurethane(STP-U)

摘要

Apart from the widely introduced silicone and polyurethane systems,also hybrid prepolymers based on silane terminated polyurethanes(STP-U) offer themselves for the preparation of sealants and adhesives.They combine the benefits of a polyurethane base structure with a silane based curing mechanism.The formulations prepared are non-hazardous with respect to health and environment and are distinguished by outstanding mechanical properties along with excellent adhesion characteristics.
