Sisu Chemical LLC has announced the introduction of two new water-based adhesives developed for transdermal patches and medical tapes. Both water-based adhesives can be used as an alternative to solvent-based adhesives where long-term adhesion properties are desired. Scibond 134 is a vinyl-acetate/acrylate emulsion polymer, while Scibond 159 is an all-acrylic version. Both have passed skin-sensitivity testing and have demonstrated excellent resistance to moisture. They have also shown low interaction with drug delivery systems used in transdermal patches.
