Henkel introduces their newly developed radiation curable PSA class. The polymer base can be described as UV-Polyurethane-Acrylate and can be applied without solvents at low viscosities at temperatures below 100^oC. The modular pre-polymer system has a very low non-polymer content, as well as an extraordinary property profile.

Additional outstanding characteristics include suitable adhesion to various surfaces, its conformity to ISO 10993 for medical devices and the exceptionally good processability in a variety of applications.

In processes and applications used in the medical market, the products have to fulfill many functional as well as legislative requirements, so the qualification of an alternative product is difficult and time consuming. The paper reports from a new UV-PU-Acrylate adhesive for medical devices, where the water vapor transmission rate is one key parameter in the area of the modern wound management. Further the adhesive has to have a very well controlled adhesive strength, so that the removal of the wound covering causes the least pain possible for the patient and provides a low-trauma-function.

In this context the new UV-PU-Acrylate adhesive system provides new opportunities, where current adhesives are limited in their performance.
