In contrast, pressure-sensitive adhesives (PSAs) form a bond simply by the application of light pressure to marry the adhesive with the adherend. Pressure-sensitive adhesives are designed with a balance between flow and resistance to flow. The bond forms because the adhesive is soft enough to flow, or wet, the adherend.
Acrylic resin as pressure-sensitive adhesive. "Super glue" is a formulation of cyanoacrylate. Polymethyl methacrylate is the clear break-resistant sheeting sold as acrylic glass (or simply acrylic sheet) or under the trade name Plexiglas, Perspex, etc.
A typical PSA tape consists of a pressure-sensitive adhesive (the sticky part of the tape) coated to a backing material. To prevent the adhesive from sticking to the backing when wound in a roll, a release agent is applied to the backing or a release liner is placed on the adhesive. Sometimes a primer is coated between the adhesive and backing ...

Pressure-sensitive adhesive is used in Post-it notes. Pressure-sensitive adhesives are manufactured with either a liquid carrier or in 100% solid form. Articles are made from liquid PSAs by coating the adhesive and drying off the solvent or water carrier.
Materials Needed: Sponge, Stovetop, Pan, Water, Drying rack Step 1: Place at least two cups of water in a pot. Step 2: Bring the water to a rolling boil on the stovetop.
The bonding temperature is lower than with most other HMAs, only about 50 °C (122 °F) to 70 °C (158 °F), when the adhesive behaves as a soft rubber acting as a pressure-sensitive adhesive. The surface wetting in this amorphous state is good, and on cooling the polymer crystallizes, forming a strong flexible bond with high cohesion.
