Methylene Chloride

(dichloromethane) [CH₂Cl₂] Clear liquid

Mainly used as a paint stripper and a degreaser. In the food industry, it is used to decaffeinate coffee and to prepare extracts of hops and other flavorings. Its volatility has led to its use as an aerosol spray propellant and as a blowing agent for polyurethane foams. It is also used as a fumigant pesticide for stored strawberries and grains. It’s used as a paint remover that does not harm wood in the removal process and can be used to reduce the flammability of other substances, decreasing the chance of in-plant fire or explosion. It’s also often necessary for the removal of grease, oil, or similar substances used as lubricants or temporary protective coatings during metal fabrication.

Oxidizer.

Potassium perchlorate until recently was used to treat hyperthyroidism resulting from Grave's disease, and is still used diagnostically to test thyroid hormone production in some clinical settings. In addition, potassium perchlorate is used in protective breathing equipment on Air National Guard (ANG) aircraft for use in the event of depressurization, and in naval emergency escape breathing devices. Other uses of perchlorate salts include in nuclear reactors and electronic tubes, as additives in lubricating oils, in solid fuels in rockets and missiles, road flares, air-bag inflation systems, in tanning and finishing leather, as a fixer for fabrics and dyes, and in electoplating, in nuclear reactors, electronic tubes, aluminum refining, rubber manufacture, and production of paints and enamels. Commonly used in fertilizers, it’s also used for analytical chemistry, in gypsum cements, glass and aluminum manufacture.

One area of natural occurrence of potassium perchlorate is in potassium nitrate from Chile (Chile saltpeter), which may be used in chemical fertilizers originating from Chile.

Wood Meal

Extremely fine, light-tan flour, much-much finer than sawdust

Used as a soil extender, as filler in a plastic resin matrix, animal feed filler, oil and water solidification, toilet seats, decking, marina products, and automotive components. Some other interesting uses of wood meal include cleaning of furs where it is a mild abrasive and oil absorbent, it is also an abrasive in soaps - especially those used by mechanics, and relatively coarse wood meal is used in silverware cleaners. Other uses include doorknobs, ornaments, and molded furniture parts.

Zinc Oxide

[ZnO] White powder

Used as a white pigment in paints. It is also used in coatings for paper. Because it absorbs ultraviolet light, zinc oxide can be used in ointments, creams, and lotions to protect against sunburn. It imparts a unique combination of properties when used in glass, such as high brilliance and luster and high stability against deformation under stress. It is added to fungicides to increase their effectiveness in specific applications. It is also used in Zinc-Carbon dry cells, Zinc-Silver Oxide batteries, Nickel Oxide-Cadmium batteries and even in secondary batteries. It is also an important ingredient in the commercial manufacture of rubber goods.

Zinc Powder

[Zn] Gray powder

+200-325 mesh

Mainly used as a protective coating of other metals, such as iron and steel. It is often alloyed with other metals, e.g., aluminium, copper, titanium and magnesium, to impart a variety of properties and mainly used for casting and for wrought applications. Further important applications are in dye-casting, and the construction industry. Zinc dust is a widely used catalyst; it is also used as a reducing and precipitating agent in organic and analytical chemistry. Inorganic zinc compounds have various applications, e.g., for automotive equipment, storage and dry-cell batteries and organ pipes.
