Résumé : |
pressure-sensitive adhesives (PSAs) represent a system that actually dates back to the invention of the self-adhesive label in 1935 when R. Stanton Avery produced the first coating unit using a wooden cigar box with two holes cut in the bottom. The box was filled with adhesive, which then dripped through the holes onto a narrow roll of paper that ran below. The thickness of the adhesive coating was regs lated by narrowing the cigar box holes with pieces of tape, producing pressure-sensitive labels that could be applied without moistening or glue.
Such "technology" seems primitive when compared to the multi-million dollar, sophisticated coaters that operate today. In medical devices, the use of PSAs provides versatility and design flexibility to meet the demands of the ever-changing marketplace. Pressure-sensitive adhesives can be defined as "a distinct category of adhesive tapes which in dry form are aggressive and permanently tacky at room temperature." PSAs will adhere to a variety of substrates when applied with pressure, and do not require activation by water, heat or sol-vent. They will have sufficient cohesive strength so they can be handled with fingers. The primary mode of bonding for a PSA is not chemical or mechanical, but rather a polar attraction with the substrate, and always requires pressure to achieve sufficient "wet out" onto the surface to obtain sufficient adhesion. |
