Title
(EN) Debondable reactive hot melt adhesives
Abstract
(EN)

The present invention relates to a reactive hot melt adhesive composition, which at least partially loses its adhesiveness upon application of an electric voltage and thus allows debonding of substrates that have been bonded using said adhesive. Furthermore, the present invention relates to a method for its production and a method for forming a bonded substrate using such a reactive hot melt adhesive composition.
