There are two types of adhesives that harden by drying: solvent-based adhesives and polymer dispersion adhesives, also known as emulsion adhesives. Solvent-based adhesives are a mixture of ingredients (typically polymers) dissolved in a solvent. White glue, contact adhesives and rubber cements are members of the drying adhesive family. As the ...
Adhesives may be broadly divided in two classes: structural and pressure-sensitive. To form a permanent bond, structural adhesives harden via processes such as evaporation of solvent (for example, white glue), reaction with UV radiation (as in dental adhesives), chemical reaction (such as two part epoxy), or cooling (as in hot melt).
In the United Kingdom of Great Britain and Ireland pre-adhesive mail was the norm before the Penny Black and Two pence Blue stamps were issued for use by the General Post Office on 6 May 1840, and in other countries, to mail used prior to each country's postal administration adopted adhesive labels to indicate postage had been pre-paid.
This led to his invention of stamp gum in 1837. The world's first adhesive postage stamp was called the Penny Black. [1] [2] Many early stamps were not gummed, however, and some have been unable to be gummed due to shortage (for instance, the typewritten Uganda Cowry stamps of 1895). Extreme tropical climates were also a problem for Curaçao ...

Athletic taping is the process of applying tape directly to the skin or over pre-wrap in order to maintain a stable position of bones and muscles during athletic activity.

These silicone covers are adhesive, meaning you simply peel back a piece of plastic and stick them on. They function exactly like a bra (and are even rounded like one) for natural-seeming ...
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 ...
