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).
