Synthesis of new solvent-borne acrylic pressure-sensitive adhesives with low shrinkage
Abstract
Polyacrylic pressure-sensitive adhesives based on 2-ethylhexyl acrylate, ethyl acrylate, methyl acrylate or acrylic acid were synthesized in ethyl acetate. The effects of kind and amount of crosslinking agent on peel adhesion and shear strength of the adhesives crosslinked with the compounds selected from the groups of metal chelates, multifunctional propylene imines or amine resins were investigated. Dependences of peel adhesion as well as shear strength of UV-crosslinked adhesives on the kind and amount of photoinitiator, crosslinking time and UV radiation dose were determined. On the basis of the results obtained the crosslinking agents were selected and their minimal amounts were found, ensuring acceptable value of film shrinkage (<0.5 %). The amount of selected crosslinking agents, needed to keep the shrinkage below this level, was determined.
