WolfISBNs978-1-56990-447-31-56990-447-2 HANSERH anser Publishers, Munich Hanser Publications, CincinnatiSample Chapter 2:Primary Polymer Adhesion Issues with Inks, Coatings, and Adhesives2 Primary Polymer Adhesion Issues withInks, Coatings, and AdhesivesWhen addressing the adhesion of polymers to interfacing materials, the primary andforemost challenge is to understand the fundamental driving forces which can initiatethe development of adhesion strength between polymer-to-polymer, polymer-to- metal ,polymer-to-ceramic, or polymer-to-inks, coatings, and adhesives. These interfaces alsoexist in multivariate environments, such as heat and humidity, which also must be exam-ined. Ultimately, it is the polymer and the interface chemistry that determine , there can be adhesion failure between the polymer and an inorganic, such asa metal , due to an oxide layer that is weakly being said, this work will focus fundamentally on the bonding issues associatedwith polymers because of their unique deformation character, low modulus, and longchain polymeric materials inherently have a low Surface energy that results in poorsurface adhesion or even complete adhesion makes it difficult for inks,paints,adhesives and other coatings to properly wet-out and adhere to the Surface of thesesubstrates.
