Contact adhesives are well known for providing tough and elastic bond lines with superior initial tear strength, making them a preferred adhesive technology for highly demanding and dynamically loaded adhesive applications in the automotive, furniture and specifically textile and footwear industry. The high molecular weight necessary to produce contact adhesive properties has so far prevented the use of this material class as an adhesive raw material in hotmelt application technology. We will report on a breakthrough in application and formulation technology for reactive hotmelts that allows the processing and application of very high molecular weight polyurethanes with excellent hot tear strength and a long cold tack life, matching the performance of 2-component contact adhesives.
