The second active ingredient is an organic solvent such as 2-butoxyethanol (ethylene glycol monobutyl ether, trade name butyl cellosolve) that acts as a wetting agent and provides a protective primer layer in conjunction with an organic polymer emulsion.
The second most important part of FBE coatings is the curing agent or hardener. Curing agents react either with the epoxy ring or with the hydroxyl groups, along the epoxy molecular chain. Various types of curing agents, used in FBE manufacture, include dicyandiamide, aromatic amines, aliphatic diamines and organic acid anhydrides. [6]
Substrate is used in a converting process such as printing or coating to generally describe the base material onto which, e.g. images, will be printed.Base materials may include:
A small transformer potted in epoxy. The surface visible on the right is formed by the potting compound that has been poured into the plastic box. In electronics, potting is the process of filling a complete electronic assembly with a solid or gelatinous compound.
J-B Weld (stylized as J-B WELD) is the name of their flagship product: a specialized, high-temperature epoxy adhesive for use in bonding materials together. The company has run advertisements showing engine block repair with J-B Weld. [2] The J-B Weld Company, founded in 1969 by Sam Bonham in Sulphur Springs, Texas, specializes in epoxy products.
Exercise resolutions shouldn’t cause you stress. Try adding a five-minute walk to your daily routine for added health benefits.
9. Cook Out. If “The Purge” were a fast-food restaurant, it would be Cookout. There is no order in this place, a place where you can get a burger, and for your “side” you can just choose ...
Polyacrylates used in adhesive tapes are readily synthesized by free-radical polymerization. [6] These polymerizations can be initiated thermally or photo catalytically using azo- and peroxide-based initiators. [6] Such polymerizations are typically carried out in solvent to produce a water-resistant, homogenous coating. [6]
