In 1977, the production of starch- and cellulose adhesives commenced and in 1990, these were followed by the first protein-based label adhesive. [4] Coca-Cola Deutschland, which was then based in Essen asked cph in 1990, to develop a special label adhesive for PET bottles. At this time the name of the company was changed to cph Deutschland GmbH.
The high tack material comprises about 95% of the adhesive and provides the majority of the adhesive's tackiness. [6] In addition to these 2 components, surfactants are often added to reduce the surface energy of the adhesive and facilitate adhesion to high surface energy substrates (metals, other polymeric materials).

Silicones are usually very thick (high viscosity), and must be vacuum degassed prior to pouring, to minimize bubble entrapment. If making a brush-on rubber mold, the curing time factor between coats is long (longer than urethanes or polysulfides, shorter than latex). Silicone components (A+B) must be mixed accurately by weight (scale required ...
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.
The chemical industry in Germany is one of the most well-established in the world, and a world leader; a quarter of the chemicals made in the EU, are made in Germany. Currently the German industry, turning over 160 billion euros [1] is the European leader, and the third-biggest in the world. It is Germany's third-largest industry, after Germany ...
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.
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 ...
Lohmann-Koester manufactures self-adhesive and mechanical closures for diapers and incontinence pads, skin-compatible hotmelt adhesives and adhesive tape for hygiene, medical and technical applications. In 1992 the company created Lohmann Technologies UK based in Buckinghamshire. It offers adhesives for manufacturers, designers and OEM customers.
