Waterborne 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 کاملDeposition Analysis of Pressure Sensitive Adhesives
In this study, a set of pulps containing different PSA products that were recycled at the Forest Products Laboratory (FPL) pilot plant were analyzed for deposition using the PIRA deposition device at North Carolina State University. The work is part of the United States Postal Service Environmentally Benign Pressure Sensitive Adhesive effort. The deposition device consists of a counter-rotating...
متن کاملAmbient Polymerization of Acrylic Pressure Sensitive Adhesives
Traditional solution acrylic polymers for pressure sensitive adhesives (PSA) are synthesized using conventional free radical initiation systems based upon organic peroxide or azo compounds 1 . Such syntheses are heat activated and employ solvent reflux temperatures during the polymerization process. The resulting acrylic polymers are formed with a relatively broad molecular weight distribution ...
متن کاملMechanics of Soft PSAs (Pressure Sensitive Adhesives)
The adhesive performances of a PSA (Pressure Sensitive Adhesive) are attributed to their viscoelastic properties. In this paper we analyze the viscoelastic behavior of different PSAs having substantially similar adhesive performance. Linear and non linear analyses were performed using small amplitude oscillatory shear tests and tensile stress-strain tests, respectively. It is shown that linear ...
متن کاملPressure-Sensitive Adhesives for Medical Applications
Since their introduction half a century ago, pressure-sensitive acrylic adhesive has been successfully applied in many fields. They are used in self-adhesive tapes, labels, sign and marking films and protective films as well as in dermal dosage systems for pharmaceutical applications, in biomedical electrodes, plasters, the assembly of automotive parts, toys, and electronic circuits and keyboar...
