Indigo

Indigo is an organic compound with a distinctive blue color. It is the blue often associated with blue jeans.Indigo is among the oldest dyes to be used for textile dyeing and printing. Many Asian countries, such as India, China, Japan, and Southeast Asian nations have used indigo as a dye.It is insoluble in water, alcohol, or ether, but soluble in DMSO, chloroform, nitrobenzene, and concentrated sulfuric acid.Indigo and some of its derivatives are known to be ambipolar organic semiconductors when deposited as thin films by vacuum evaporation.

Orcein

Orcein are names for dyes extracted from several species of lichen. Orcinol is extracted from such lichens. It is then converted to orcein by ammonia and air. In traditional dye-making methods, urine was used as the ammonia source.It is red in acidic pH and blue in alkaline pH. It forms dark brown crystals. It is a mixture of phenoxazone derivates - hydroxyorceins, aminoorceins, and aminoorceinimines.

SR507A

SR507A is a trifunctional monomer that can be used to enhance hardness, heat and solvent resistance, and electrical properties in polymer systems including polyolefins, epoxies, polyesters, and polyvinyl chloride.

Aniline

Aniline is an organic compound. Aniline was first isolated by destructive distillation of indigo by Otto Unverdorben. Aniline is the prototypical aromatic amine. Its main use is in the manufacture of precursors to polyurethane. Aniline is mainly produced in industry in two steps from benzene. First, benzene is nitrated using a concentrated mixture of nitric acid and sulfuric acid at 50 to 60 °C, which gives nitrobenzene. In the second step, the nitrobenzene is hydrogenated, typically at 200–300 °C in presence of various metal catalysts. Aniline reacts with carboxylic acids or more readily with acyl chlorides such as acetyl chloride to give amides. Aniline and its ring-substituted derivatives react with nitrous acid to form diazonium salts. It reacts with nitrobenzene to produce phenazine in the Wohl-Aue reaction.

Carmine

Carmine is a pigment of a bright red color obtained from the carminic acid produced by some scale insects, such as the cochineal and the Polish cochineal, and is used as a general term for a particularly deep red color of the same name. Carmine is used in the manufacture of artificial flowers, paints, crimson ink, rouge, and other cosmetics, and is routinely added to food products such as yogurt and certain brands of juice, most notably those of the ruby-red variety. Carmine can be used as a staining agent in histology, as a Best's carmine to stain glycogen, mucicarmine to stain acidic mucopolysaccharides, and carmalum to stain cell nuclei.Carmine was used in dyeing textiles and in painting since antiquity.

Properties Suppliers
Ceraglo

Ceraglo is a phosphate based water stain. Ceraglo is a free-flowing acidic liquid concentrate intended for dilution with hot or cold water. It is safe and pleasant to use and at the same time highly efficient for the removal of rust and scale by chemical action. Ceraglo also contains powerful wetting agents and solvents which enable it to leach dirt which has penetrated the surface being treated. It has been specially formulated so that it has no unpleasant smell, nor will it leave any after use. Ceraglo is not a degreaser.
