Blu Tack is a reusable putty-like pressure-sensitive adhesive produced by Bostik, commonly used to attach lightweight objects (such as posters or sheets of paper) to walls, doors or other dry surfaces. Traditionally blue, it is also available in other colours.
Chemical structure of ethyl cyanoacrylate, the precursor to many commercial adhesives. The most common monomer is ethyl cyanoacrylate.Several related esters are known. To facilitate easy handling, a cyanoacrylate monomer is frequently formulated with an ingredient such as fumed silica to make it more viscous or gel-like.
The tack or ‘’quick stick’’ characteristics are critical for the initial bonding to the intended substrate; cool temperatures can make a PSA too firm, losing its tack. Once applied, temperature affects the performance on its intended use: Heat can soften an adhesive, reducing its shear holding ability.
Adhesive removers are often based on organic solvents, which can dissolve or soften many adhesive polymers that do not dissolve in water. They may also contain a gelling agent, increasing viscosity so that the product sticks to the area to be treated rather than running off. Common solvents used include D-limonene, aliphatic alkanes, and acetone.
Pressure-sensitive tape or pressure-sensitive adhesive tape (PSA tape) is an adhesive tape that sticks when pressure is applied without the need for a solvent (such as water) or heat for activation. It is also known in various countries as self-stick tape , sticky tape , or just adhesive tape and tape , as well as genericized trademarks , such ...
Dennison Mending Tape from the second half of the 20th century. From the Museo del Objeto del Objeto collection. Pressure-sensitive tape, PSA tape, self-stick tape or sticky tape consists of a pressure sensitive adhesive coated onto a backing material such as paper, plastic film, cloth, or metal foil. It is sticky (tacky) without any heat or ...

Tackifiers are chemical compounds used in formulating adhesives to increase tack, the stickiness of the surface of the adhesive. [1] They are usually low-molecular weight compounds with high glass transition temperature. At low strain rate, they provide higher stress compliance [clarification needed], and become stiffer at higher strain rates.
