Drying, lacquer oxidative

Japanese lacquer. These lacquers are a type of oleoresin that dry by oxidation in a damp atmosphere.14... 

Both drying and semi-drying oils can be used to make alkyd resins which dry by oxidation. Nondrying oils give alkyds suitable as plasticizers, particularly for nitrocellulose lacquers or stoving amino resin paints. 

Some time before 200 b.c., the Chinese used an exudate from the conifer Rhus verniciflua (later known as the varnish tree) as a coating. The process was further developed in Japan, where by a.d. 400 the product was known as Japanese lacquer. These lacquers are a type of oleoresin that dries by oxidation in a damp atmosphere. 

The first true lacquer was developed in Japan from the sap of a sumac tree Rhus vernicera) during the Chou dynasty about 3000 years ago. Japanese lacquers are a type of oleoresin, which dries by oxidation in a damp atmosphere. 

The presence of the unsaturated substituent along this polyester backbone gives this polymer crosslinking possibilities through a secondary reaction of the double bond. These polymers are used in paints, varnishes, and lacquers, where the ultimate cross-linked product results from the oxidation of the double bond as the coating cures. A cross-linked polyester could also result from reaction (5.J) without the unsaturated carboxylic acid, but the latter would produce a gel in which the entire reaction mass solidified and is not as well suited to coatings applications as the polymer that crosslinks upon drying. ... 

Dubois-Raymond Explosives (Fr). Proposed in 1892, mixtures which contained combustible materials such.as naphthalene, anthracene, camphor, etc together with oxidants, such. as nitrates, chromates, etc. To these was added tar, varnish, lacquer or a drying oil. 

Nail polish consists of flexible lacquers, pigments such as organic dyes, iron or chromium oxides, and ultramarine blue along with drying agents and binders or vehicles such as ethyl acetate that evaporate on drying. Nail polish remover is usually an organic solvent such as acetone or ethyl acetate. 

One can further divide lacquers according to their drying processes into oxidative drying, cold hardening, irradiation hardening and oven drying. 

The body and ogive are now reassembled and soldered together. Seal the inside of this assembly with a heavy coat of red oxide lacquer primer. This prevents possible reactions between the explosive and the metal surface of the grenade. When dry, fill the body/ ogive section with the explosive filler of your choice Complete how-to info for several different examples of both load types have been detailed in PMA Volume One and Volume Two issue 2.
