Introducing a new hotmelt adhesive technology matching the performance of PU dispersions

Waterborne aliphatic polyurethane adhesives are well known for providing tough and elastic bond lines with superior hot tear strength, making them the preferred adhesive technology for highly demanding and dynamically loaded adhesive applications in automotive, furniture and specifically footwear industry. Their high molecular weight and limited thermal stability have so far prevented their use as adhesive raw material in hotmelt application technology. We will report on a breakthrough in application and formulation technology for polyurethane hotmelts that allows the processing and application of very high molecular weight polyurethanes, matching the performance of heat activated polyurethane adhesives.
