Effect of Monomer Composition on Adhesive Performance for Waterborne Acrylic Pressure-Sensitive Adhesives
A series of pressure-sensitive adhesives (PSAs) with different monomer composition was prepared using emulsion polymerisation. The monomers were butylacrylate (BA), 2-hydroxyethyl acrylate (2-HEA), acrylic acid (AA) and 2-ethylhexyl acrylate (2-EHA). The adhesive performance was studied at 4%, 8% and 12% 2-EHA content based on total monomer (BOTM) composition. The adhesives obtained with consta...
متن کاملpH dependence of the properties of waterborne pressure-sensitive adhesives containing acrylic acid.
Polymer colloids are often copolymerized with acrylic acid monomers in order to impart colloidal stability. Here, the effects of the pH on the nanoscale and macroscopic adhesive properties of waterborne poly(butyl acrylate-co-acrylic acid) films are reported. In films cast from acidic colloidal dispersions, hydrogen bonding between carboxylic acid groups dominates the particle-particle interact...
متن کاملWaterborne polyurethane-acrylic hybrid nanoparticles by miniemulsion polymerization: applications in pressure-sensitive adhesives.
Waterborne polyurethane-acrylic hybrid nanoparticles for application as pressure-sensitive adhesives (PSAs) were prepared by one-step miniemulsion polymerization. The addition of polyurethane to a standard waterborne acrylic formulation results in a large increase in the cohesive strength and hence a much higher shear holding time (greater than seven weeks at room temperature), which is a very ...
متن کاملSkin Development during the Film Formation of Waterborne Acrylic Pressure-Sensitive Adhesives containing Tackifying Resin
Tackifying resins (TR) are often used to improve the adhesive properties of waterborne pressure-sensitive adhesives (PSAs) derived from latex dispersions. There is a large gap in the understanding of how, and to what extent, the film formation mechanism of PSAs is altered by the addition of TR. Herein, magnetic resonance profiling experiments show that the addition of TR to an acrylic latex cre...
متن کاملProbing particle structure in waterborne pressure-sensitive adhesives with atomic force microscopy.
There is a need to know the nanostructure of pressure-sensitive adhesive (PSA) films obtained from waterborne polymer colloids so that it can be correlated with properties. Intermittent-contact atomic force microscopy (AFM) of an acrylic waterborne PSA film identifies two components, which can be attributed to the polymer and the solids in the serum (mainly surfactant). It is found that when th...
