Electronic materials pressure sensitive adhesives (PSAs) are a type of adhesives that can adhere to solid surfaces under light pressure and short contact time, without the need for curing or solvent evaporation. PSAs are widely used in various electronic applications, such as tapes, labels, protection films, and medical devices.
PSAs can also provide additional functions, such as shock absorption, thermal and electrical conductivity, electromagnetic shielding, and optical property. One example of PSAs for electronic applications is optically clear adhesives (OCA), which are used as a core material for optical performance of display devices.
OCA can improve the brightness, contrast, and color reproduction of displays by eliminating air gaps and reducing reflection between the display components. OCA can also protect the display from dust, moisture, and mechanical stress
Electronic materials pressure sensitive adhesives (PSAs) work by achieving the correct balance between flow and resistance to flow. They are viscous and elastic materials that can wet the surface of the substrate on contact and form a bond without any chemical reaction or physical change.
PSAs can also provide additional functions by incorporating various additives, such as conductive particles, photo responsive molecules, or bioinspired compounds. These additives can enhance or modulate the adhesion performance of PSAs under different conditions, such as underwater, light irradiation, or temperature change.
PSAs are typically coated onto a backing material, such as paper, plastic, or fabric, and then cut into smaller pieces and packaged as tapes or labels. PSAs can be applied to various substrates by applying light pressure and can be peeled off without leaving any residue
PSAs are formulated by polymerizing different types of acrylic monomers, such as alkyl acrylates, acrylic acid, or methacrylic acid, to obtain high molecular weight polymers with various properties. PSAs can also be modified by adding various additives, such as crosslinkers, tackifiers, fillers, pigments, or stabilizers, to enhance or adjust the adhesion performance.
PSAs are applied by coating them onto a backing material, such as paper, plastic, or fabric, using various methods, such as knife coating, curtain coating, gravure coating, slide coating, or extrusion. PSAs can be delivered as solution, emulsion, radiation curable, or hot-melt materials1. PSAs can adhere to various substrates by applying light pressure and can be peeled off without leaving any residue
