Acrylic Pressure-Sensitive Adhesives Containing SiO₂ Nanoparticles

Abstract

The use of acrylic pressure-sensitive adhesives (PSAs) is increasing in a variety of industrial fi elds. They have been applied in the manufacture of mounting tapes, self-adhesive labels, protective fi lms, masking tapes, splicing tapes, carrier-free tapes, sign and marking fi lms, and in diverse medical products, such as pads or self-adhesive bioelectrodes. In this study, the application of SiO 2 nanoparticles in acrylic PSA was investigated. The properties of the newly synthesized and modifi ed PSA were evaluated via the tack, peel adhesion, shear-strength and shrinkage. It has been found that the nanotechnologically-reinforced systems consisting of monodisperse non-agglomerated SiO 2 nanoparticles and self-crosslinked acrylic PSAs showed a great enhancement in tack, peel adhesion, shear resistance and shrinkage, without showing the disadvantages known to result from the use of other inorganic additives. In this paper we evaluate the performance of SiO 2 nanoparticles with a size of about 30 nm as inorganic fi ller into the synthesized solvent-borne acrylic PSA.

Aging of silicone pressure-sensitive adhesives

“…A shrinkage larger than 0.5% or larger than 0.5 mm exceeds the permissible shrinkage [13][14][15][16][17].…”

Citric acid modified potato starch films containing microcrystalline cellulose reinforcement - properties and application

“…The research on solvent‐borne water‐soluble pressure sensitive adhesives (PSA) based on acrylics is an interesting challenge. They could find application as splicing tapes in paper industry, water‐dispersible labels, medical devices (i.e., surgical tapes, bio‐electrodes, and self‐adhesive hydrogels) .…”

Heat resistance of acrylic pressure‐sensitive adhesives based on commercial curing agents and UV/heat curing systems

“…The heat resistance of acrylic PSAs depends on the structure of monomer and cohesion strength of polymers. It is worth noting that the cured acrylic PSAs contain sufficient cohesion strength than that of the untreated PSAs …”
