Aurin

Aurin is an organic compound, forming yellowish or deep-red crystals with greenish metallic luster. It is soluble in strong acids to form yellow solution, or in aqueous alkalis to form carmine red solutions. Due to this behaviour it can be used as pH indicator with pH transition range 5.0 - 6.8. It used as intermediate in manufacturing of dyes.

Properties Suppliers
Metol

Metol is a developing agent used in black & white photographic developers. In its pure form, it is a solid rather light-sensitive chemical which is the half sulfate (hemisulfate) salt of N-methyl-p-aminophenol. It is also used as hair dye intermediate.

Properties Suppliers
SR533

SR533 is a trifunctional monomer that can be used to enhance hardness, heat and solvent resistance, and electrical properties in polymer systems including, polyolefins, epoxies, polyes-ters, and polyvinyl chloride.

Properties
SYMIC

SYMIC are pearlescent pigments based on synthetic mica substrates that are refinished by the application of advanced coatings and special classification technologies. Its special strengths are the optical effects and its outstanding resistance to the weather and to chemicals, along with excellent intercoat adhesion.

Properties
BC 403

BC 403 silicone glycols are a combination of polydimethylsiloxane with polyoxyalkylene materials. They are also known as silicone polyethers or Dimethicone Copolyols. This combination gives properties which are unique to this type of material.

Carbon

Carbon is nonmetallic and tetravalent-making four electrons available to form covalent chemical bonds. The major economic use of carbon other than food and wood is in the form of hydrocarbons, most notably the fossil fuel methane gas and crude oil (petroleum). Crude oil is used by the petrochemical industry to produce, amongst others, gasoline and kerosene, through a distillation process, in refineries. Cellulose is a natural, carbon-containing polymer produced by plants in the form of cotton, linen, and hemp. Cellulose is mainly used for maintaining structure in plants. Commercially valuable carbon polymers of animal origin include wool, cashmere and silk. Plastics are made from synthetic carbon polymers, often with oxygen and nitrogen atoms included at regular intervals in the main polymer chain. The raw materials for many of these synthetic substances come from crude oil. It can form alloys with iron, of which the most common is carbon steel. Graphite is combined with clays to form the 'lead' used in pencils used for writing and drawing. It is also used as a lubricant and a pigment, as a molding material in glass manufacture, in electrodes for dry batteries and in electroplating and electroforming, in brushes for electric motors and as a neutron moderator in nuclear reactors. Gem quality diamond is used in jewelry, and Industrial diamonds are used in drilling, cutting and polishing tools for machining metals and stone. Carbon black is used as the black pigment in printing ink, artist's oil paint and water colours, carbon paper, automotive finishes, India ink and laser printer toner. It is also used as a filler in rubber products such as tyres and in plastic compounds. Carbon acts as a macronutrient for the body, and is thus greatly required.

Chitin

Chitin is a long-chain polymer of a N-acetylglucosamine, a derivative of glucose, and is found in many places throughout the natural world. It is the main component of the cell walls of fungi, the exoskeletons of arthropods such as crustaceans and insects, the radulas of mollusks and the beaks of cephalopods, including squid and octopuses. Chitin may be compared structurally to the polysaccharide cellulose and functionally to the protein keratin. Chitin has also proven useful for several medical and industrial purposes. It is used as an additive to thicken and stabilize foods and pharmaceuticals. It also acts as a binder in dyes, fabrics, and adhesives. Industrial separation membranes and ion-exchange resins can be made from chitin.

Properties Suppliers
Cobalt

Cobalt is found naturally only in chemically combined form. It is used in the preparation of magnetic, wear-resistant and high-strength alloys. Cobalt silicate and cobalt(II) aluminate give a distinctive deep blue color to glass, smalt, ceramics, inks, paints and varnishes. Lithium cobalt oxide is widely used in lithium ion battery cathodes. Several cobalt compounds are used in chemical reactions as oxidation catalysts. Other uses of cobalt are in electroplating, owing to its attractive appearance, hardness and resistance to oxidation, and as ground coats for porcelain enamels.
