Decel Methyl

PRODUCT : CH3 OCH2 CH2 OH
  2 - Methoxyethanol
  Ethylene Glycol Mono Methyl Ether
  Methyl Glycol
  Methyl Cellosolve

TECHNICAL DETAILS :

Ethylene glycol mono methyl ether, methyl glycol is a colourless, slightly hygroscopic liquid with a mild odour. It is miscible with water and many organic liquids and forms an azeotropic mixture with water. Methyl Glycol has good solvent power for natural and synthetic resins, particularly nitrocellulose and ethyl cellulose and can be diluted to a considerable extent with toluene and xylene. It contains a hydroxyl group and can consequently be converted into esters and ethers.

SOLVENT POWER

DECEL METHYL is an excellent solvent for nitrocellulose, celluloid, cellulose acetate, cellulose acetobutyrate, ethanol - soluble resins, chlorinated rubber, polyvinyl acetate, polyacrylates, novolaks, and resolves, and for urea formaldehyde, melamine formaldehyde, alkyd, maleic aldehyde and ketone resins. It is also a good solvent for cellulose ethers when mixed with low-boiling solvents such as methyl acetate, acetone or methylene chloride. It is miscible in all proportions with castor oil and the common plasticizers.

DECEL METHYL does not dissolve in dammer, rubber, bitumen, mineral oils, stand oils, vegetable oils (except castor oil), hydrocarbon - soluble resins, polystyrene, unmodified polyvinyl chloride (lacquer grade), polyvinyl carbazole or indene resins.

Colophony glyceryl esters, Manila copal, polyvinyl butyrals and coumarone resins are only soluble with difficulty. A number of other plastics materials such as vinyl acetate / vinyl chloride / dicarboxylic acid copolynersm chlorinated polyvinyl chloride, polyvinyl formal and resinic acid - modified phenolic resins swell in methyl glycol.

APPLICATIONS

Because of its high solvent power, when used together with low boiling solvents, DECEL METHYL is employed with particular advantage in cellulose acetate and cellulose ether lacquers. Although it has a rather high boiling point, film formation is rapid owing to its relatively high evaporation rate. DECEL METHYL is such a good solvent for nitro cellulose that it may be used in the production of very highly concentrated lacquer solutions which dry and set within a comparatively short time. It can, further-more, be used with advantage for regulating the evaporation time and the flow of cellulose ether lacquers. For this purpose it may be diluted to a large extent with toluene or ethanol.

DECEL METHYL tends to absorb water readily and is therefor always mixed with methoxybutanol or butanol in order to prevent 'blushing' of the lacquer film on drying. If cellulose lacquers containing DECEL METHYL are supplied to stained wood, the solvent dissolves part of the stain out of the wood, giving slightly coloured lacquer films. DECEL METHYL may also be used in the dyeing of leather. DECEL METHYL does not attack rubber.

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