Waterbased acrylic pressure sensitive adhesive types are categorized based on performance properties, application targets, and formulation adjustments, each designed to meet specific bonding requirements across industries. Removable types offer low to moderate adhesion, allowing clean removal without residue, used in labels, post-it notes, and temporary tapes; they feature low tackifier levels and flexible monomers for easy release. Permanent types provide high adhesion and shear resistance, ideal for packaging tapes, automotive trim, and structural bonding; they use higher crosslinking and polar monomers to enhance substrate bonding. High-temperature resistant types withstand 100–150°C, formulated with heat-stable monomers (methyl methacrylate) and robust crosslinkers, used in engine compartments and electronics. Low-temperature resistant types maintain flexibility below 0°C, using 2-ethylhexyl acrylate and plasticizers, suitable for frozen food packaging and winter outdoor applications. Medical-grade types prioritize biocompatibility, hypoallergenic formulation, and gentle skin adhesion, used in tapes and dressings, compliant with ISO 10993. Clear types feature high-purity monomers and minimal additives for optical clarity, used in transparent labels and display applications. UV-resistant types include UV stabilizers to prevent degradation in outdoor use, such as signage and automotive labels. Each type is tailored through monomer selection, crosslinking levels, and additive packages, ensuring they deliver the precise performance needed for their intended application, from temporary bonding to long-term, harsh-environment use.
