Crosslinkable propyleneimine pressure-sensitive adhesive acrylates and their pot life

摘要

In this article a new generation of crosslinkers based on multifunctional propyleneimine derivatives involving crosslinking reactions of acrylic pressure-sensitive adhesives (PSAs) were investigated. Their tack, peel adhesion, and shear strength after crosslinking, as well as their viscosity and pot life were also measured. Crosslinking of PSAs is an established technology used in many industrial manufacturing processes. Their novel applications and technical specifications stimulate continuous research and development into new crosslinkers with very interesting characteristics.
