PRODUCT : CH3 (OCH2 CH2)2 OH
  2 – (2- Methoxyethoxy) Ethanol
  Diethylene Glycol Mono Methyl Ether
  Methyl Diglycol
  Methyl Carbitol

TECHNICAL DETAILS :

DECAR METHYL is a colourless, slightly hygroscopic, high boiling liquid with a mild odour. It is completely miscible with water and most organic solvents. In addition, it has good solvent power for nitrocellulose and can be diluted to a considerable extent with organic solvents. It forms binary azeotropic mixtures with some organic substances.

SOLVENT POWER

DECAR METHYL readily dissolves nitrocellulose, celluloid, Colophony and its ester resins, Manila copal; phenol formaldehyde urea formaldehyde, melamine formaldehyde and other condensation resins, alkyd and other ethanol – soluble maleic resins, and also in Uresin B (carbamaate resins). Polyvinyl butyrals, Polyvinyl Acetate, Epoxy resins and polyvinyl ether, the commonly used plasticizers, chlorinated diphenylls, certain vegetable oils (castor oil and inseed oil), essential oils and turpentine. Shellac, ethyl cellulose, benzyl cellulose, cellulose acetate, chlorinated rubber, polyacrylates and polymethacrylates, coumarone resins, certain special plasticizers and some polyvinyl chloride resins are all only soluble in DECAR METHYL with some difficulty.

Natural resins, coal tar, cellulose acetobutyrate, polyvinyl formal and certain polymers such as polyvinyl chloride swell in DECAR METHYL or are only partially soluble.

Dammar, natural rubber, polychlorobutadiene, bitumen, polyisobutylene, polystyrene, polyvinyl carbazole, polyvinyl alcohol’s most natural and synthetic waxes, ozokerite, paraffin wax, mineral oils, linseed oil and wood oil are practically insoluble in DECAR METHYL.

APPLICATIONS

DECAR METHYL is a relatively non-volatile solvent and is therefore only included in special lacquer formulations, principally nitrocellulose lacquers, to improve the properties of the lacquers. It can be stabilized with 2, 6 ditert – butyl – 4 – methylphenol (0.005%). Owing to its low volatility, only small quantities can be added to lacquer solutions. The dilution capacity of DECAR METHYL is very good.

DECAR METHYL does not attack rubber. DECAR METHYL is also used in the printing ink industry and in the production of ball point pen inks.

DECAR METHYL is used as Anti Icing Chemical (i.e. as aviation fuel additive).
