عنوان انگلیسی Evaluation of Adhesion Properties of Acrylic/Silicone Pressure Sensitive Adhesives Blends
چکیده انگلیسی مقاله In this study the blends of acrylic/silicone pressure sensitive adhesive (PSA) were prepared, and their adhesion properties and surface morphology were evaluated. For this purpose appropriate amounts of acrylic (10- 90%w/w) were added to silicone PSA to obtain visually homogeneous solution. The resulting solution was evenly applied on a polyethylene terephthalate (PET) film with final specific thicknesses (35, 65 and 110 μm) by using a film applicator. The morphological analysis was performed through scanning electron microscopy (SEM) and by the study of thermal analysis using the differential mechanical thermal analysis (DMTA) behavior of the blends, and it was found that all acrylic/silicone blends were incompatible and showed two different glass transition temperatures. By addition of silicone from 10 to 50% to acrylic/silicone blends the continuous phase is acrylic and the dispersed phase is silicone. Equally by increasing the percentage of silicone in the blends the continuous and dispersed phases were interchanged. By study of surface analysis and peel strength results it was found that surface properties are the main factors to determine peel strength values. Viscoelastic studies of the blends were shown that tack values and G" showed the same changing trend.
