DECEL CELLOSOLVE 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. It 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

CELLOSOLVE is an excellent solvent for nitrocellulose,
celluloid, ethanol - soluble resins, chlorinated rubber,
polyvinyl acetates, polyvinyl butyrals, aldehyde and
ketone resins, urea formaldehyde and melamine formaldehyde
resins and polyacrylates. It dissolves cellulose ethers
more readily than does methyl glycol. Mixed with methylene
chloride, ethylene chloride or low boiling esters,
it also dissolves cellulose acetate. It also dissolves
castor oil and linseed oil. It is miscible with the
CELLOSOLVE will not dissolve dammar, rubber bitumen,
cellulose acetate, ester gums, polystyrene, unmodified
polyvinyl chloride (for lacquers), polyvinyl carbazole
as well as mineral oils or some vegetable oils. Shellac,
chlorinated polyvinyl chloride and a number of other
synthetic resins swell in DECEL CELLOSOLVE.
CELLOSOLVE is a very useful solvent for leather seasoning.
As a coupling agent in the production of emulsifiable
oils, additive for hydraulic fluids and metal degreasing
agent. DECEL CELLOSOLVE is particularly valued as
a slowly evaporating and pleasantly odoured solvent
for use in the production of lacquers from nitrocellulose
and cellulose ethers. Its high dilution capacity for
ethanol, toluene and white spirit of great advantage
in lacquer solutions. It surpasses many other technical
solvents in this respect.
DECEL CELLOSOLVE is combined in a lacquer with large
quantities of diluents, because of its low rate of
evaporation, it is still present in the last traces
of solvent evaporating. Owing to its high solvent
power for the non-volatile constituents, it thus greatly
aids the formation of a clear lacquer film.
quantities of DECEL CELLOSOLVE may be added to nitrocellulose
and cellulose ether lacquers (particularly the latter)
to increase their dilution capacity, to control their
evaporation rate and to improve their flow and gloss.
A certain degree of moisture is also tolerated without
its causing "blushing" or turbidity of the
drying lacquer film. If a lacquer solution contains
resins that are relatively insoluble in DECEL CELLOSOLVE
e.g. ester resins or phenol formaldehyde resins, then
the proportion of active solvents for these must be
high enough to hold them in solution during the drying
CELLOSOLVE dissolves dried nitrocellulose lacquer
films only slowly, it is excellent in brushing lacquers
for application to oil cloth, rubber cloth and other
fabrics and for general use in lacquers intended for
application as at multicoat system. Mixtures of DECEL
CELLOSOLVE with ethyl glycol acetate have also proved
useful for this purpose. DECEL on account of its mild
odour, is used in lacquers whenever a stronger smelling
solvent is undesirable. For this application, it is
usually mixed with ethanol.
addition of small quantities of DECEL CELLOSOLVE to
alkyd resin lacquers and cellulose ether lacquers
considerably reduces their viscosity and thus improves
their brushabililty. For cellulose ether lacquers
in particularly, DECEL CELLOSOLVE can hardly be surpassed
as an auxiliary solvent. It may also be used with
advantage in cleaning agents and paint strippers.
A number of vegetable oils can be very rapidly dispersed
in water by using DECEL (CELLOSOLVE). It may also
be used to improve the stability of such emulsions.
CELLOSOLVE does not attack rubber.
is also used as a solvent for "Epikote"
resins and for the resins and plastics used in the
coating of transparent and non-transparent paper to
produce waterproof or glossy layers. DECEL
CELLOSOLVE is a low volatile solvent used for regulating
drying time, for improving dilutability (e.g. with
petrol) and flow properties as well as for preventing
blushing of lacquer films. Its low volatility is also
utilised for reducing the viscosity at alkyd resin
varnishes and to improve their spreadability.
CELLOSOLVE can be used in screen, gravure and flexographic
ink formulation based on nitrocellulose. This
basic requirement for screen inks are; good flow properties,
moderate drying rate and low solid content for easy
flow through the screen (but maintaining opacity for
single coat application). Because of its evaporation
rate, it is readily adaptable to the requirements
of the system. If an especially high boiling solvent
is required, DECEL CELLOSOLVE can be used.
typical solvent formulation
for a screen ink could be as follows;-
DECEL CELLOSOLVE - 59.0(% by weight)
High Aromatic Solvent - 25.0(% by weight)
Butyl Acetate - 16.0(% by weight)
CELLOSOLVE is also used as an active solvent in spirit
based flexographic and gravure inks. These inks are
formulated on low nitrogen content nitrocellulose
(the alcohol - soluble grades) about 20% of active
solvent being added as an aid to solubilisation. DECEL
(CELLOSOLVE) solvents being true solvents for nitrocellulose
can therefore be used in this application.
