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.
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 ...
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).

Numerous products like shaving cream or shampoo were launched in the 1930s. When Beiersdorf celebrated its 50th company anniversary in 1932, it already employed more than 1.400 employees.

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.
Tesa SE is a German company manufacturing adhesive products. Founded in 2001, the company was previously a division of Beiersdorf, remaining a subsidiary thereof after becoming an independent company. [4] In Germany, the brand name has become synonymous with adhesive tape, [5] [6] and is listed in the Duden dictionary as such. [7]
