New generation of crosslinking agents based on multifunctional methylaziridines

This publication describes new generation of crosslinking agents based on methylaziridine derivates, crosslinking reaction of pressure-sensitive acrylic adhesives (PSA) and their performance after crosslinking such as tack, adhesion and cohesion. Crosslinking of PSA is an established technology used in many industrial manufacturing processes. New applications and technical specifications stimulate the continuous development of new crosslinking agents with very interesting properties. The weak point of methylaziridine crosslinker systems, which is their very short pot life, is examined. (c) 2006 Published by Elsevier Ltd.
