Copydex

	Copydex Copydex is a common latex-based rubber cement in the UK. It can be easily recognised by its characteristic "fishy" odour. It has been owned since 1986 by Henkel. Uses Also known as "fishy glue" this contact adhesive is commonly used when sticking a variety of materials, such as paper, board, upholstery, and carpet. It is used widely by model makers as a "mask" to protect areas during airbrushing. It can be used as an alternative to Table Tennis glue. Copydex is also frequently used to apply false eyelashes in the theatre to make sure they stay on during entire performances. Composition Unlike many other rubber cements, it consists of latex dissolved in water. As such it is relatively non-toxic and so is frequently used in primary schools. It also contains ammonia Ammonia is an inorganic compound of nitrogen and hydrogen with the formula . A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a distinct pungent smell. Biologically, it ...

picture info	Rubber Cement Rubber cement (cow gum in British English) is an adhesive made from elastic polymers (typically latex) mixed in a solvent such as acetone, hexane, heptane or toluene to keep it fluid enough to be used. This makes it part of the class of drying adhesives: as the solvents quickly evaporate, the rubber solidifies, forming a strong yet flexible bond. Composition Rubber cement is simply a mixture of solid rubber in a volatile solvent that will dissolve it. When the cement is applied, the solvent evaporates, leaving the rubber as the adhesive. Almost any rubber (pre-vulcanized or not) can be used. The rubbers used might be natural rubber, gum mastic or gum arabic. Early solvents used included chloroform and benzene. A small percentage of alcohol is often added to the mix. In the United States, current formulations include n-heptane. In the United Kingdom, a product called Marabu-Fixogum uses acetone, while a product called Copydex uses ammonia. Many special compositions include h ...

They marketed his first product, "Universalwaschmittel", a universal detergent base ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Ammonia Ammonia is an inorganic compound of nitrogen and hydrogen with the formula . A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a distinct pungent smell. Biologically, it is a common nitrogenous waste, particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to 45% of the world's food and fertilizers. Around 70% of ammonia is used to make fertilisers in various forms and composition, such as urea and Diammonium phosphate. Ammonia in pure form is also applied directly into the soil. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceutical products and is used in many commercial cleaning products. It is mainly collected by downward displacement of both air and water. Although common in nature—both terrestrially and in the outer planets of the Solar System—and in wide use, ammonia is both caust ...
