Adhesives
Containment Of Costly Solvents.
The “Closed-System” design of the Daymax means
that solvents can be contained. This not only saves
raw material costs but minimizes dusting problems
and contributes to a cleaner working environment.

up profits for adhesive producers.

Higher Quality Dispersions.
Finer dispersions can be achieved in the Daymax.
Many times, the Daymax alone can equal or exceed
dispersions made with a dissolver and additional
refining equipment.
Energy Efficient
Conventional Dispersers lose 20-25% of power in
transmission. The direct drive of the Daymax utilizes
100% of the motor power. Result: Energy Savings.
Higher Viscosity Range.
With the Rotating-Baffle, can be used with heavy
viscosity adhesives, up to the 60-80,000 CPS range.

Easy Of Cleaning.
The Daymax is “Self-Cleaning”, which adds to
increase productivity due to fast cleaning times.
Varnish
How To Reduce
Varnish Costs By 25%
Originally, the Daymax was designed for Mfrg. Of
aniline printing inks containing solid synthetic
resins dispersed hot or cold in hydrocarbon
solvents such as alcohol, acetone, acetate, and
toluene. Today, it is equally efficient in the production of heliographic and othe r water-based inks,
litho ink premixes, newspaper inks, heat-set offset
inks and a variety of varnishes.
Captive Varnish Making Saves
One Ink Maker $300,000 Annually.
A medium-size East Coast inkmaker has documented
cost savings of 25% on his varnish production using
the Daymax. This translates to a savings of up to 30
Cents per pound on his annual production of One
Million pounds of final ink products. And, in the
bargain, he is attaining a superior quality of varnish
and eliminating varnish aging problems.
Absolute Safety.
The Daymax disperser/mixer, utilizing a closed processing system, assures operating safety throughout
the range of inkmaking operations. This is especially
critical for In-House varnish production where explosions involving gas-fired open kettles are not quite
uncommon. The Daymax unit is a smart investment
even without considering its cost saving features.
Unexcelled Productivity and Versatility
The Daymax will disperse much faster than dissolvers
or comparable high speed mixers…
2 to 10 times
faster.
One ink producer reports dispersing water
based flexo-inks in 30 Minutes, as opposed to the
One Day and a Half it took in a ball mill, with better
quality.
Pigment Blends
Daymax Advantages Against Top Driven Dissolvers
On a typical example, one plant replaced several top entering dissolvers and
Three-Roll-Mills with considerable savings in time & labor, improvement in quality
and in batch-to-batch uniformity. Daymax units are dedicated for different colors
to minimize cleaning & cross contamination. Previously, 1 Hour & 45 Minutes was
required to prepare 700 Lbs through a top entering dissolver and Three-Roll-Mills.
Now they can prepare 7,000 Lbs TiO2 dispersion batch in 4 Hours. Because of the
nature of operation, more than 50% of the time is used up in loading the materials.
The mix is run for additional time after loading, to obtain a dispersion of 4 on
Hegman gauge. As a rule of thumb, this plant allows about 1/2 Hr of extra mixing
time per 1,000 Lbs of solids in the mix, after all the solids have been added.
Chilled water at 45° to 50° F is circulated in the jacket. The maximum product temperature reached during
dispersion is about 175° F and is well within the allowable limits.
The Daymax prepares a dispersion of TiO2 and other pigments in a plasticizer blend and from here the
dispersion is sent to a mixer for compounding and then to a Banbury mill and a calendering line.
Good quality predispersed pigment enables this manufacturer to obtain the maximum color development.
The resin compound is plasticized in a Banbury and the calendering line is used to produce the vinyl
sheeting. The colored flexible vinyl sheets are used for various end use applications such as upholstery.
Plastisols
Daymax Advantages Against Top Driven Dissolvers
For production of the highest quality plastisols and organisols. This high shear
disperser thoroughly disperses the PVC resin and extender pigments in the
plasticizer in a minimum length of time. No milling on three roll mills is needed
following the Daymax dispersion cycle.
You will get approximately a 2-3% gain in actual yield when the Daymax is used
in dispersion. This increase is due to the fact that there is not the usual loss of
product caused by transferring it to and from several vessels and machines.
All viscosities except the very highest are handled on the Daymax. Heat build-up
long a problem in plastisol manufacturing, is minimized with the Daymax
because the dispersion cycle is generally very short in comparison with that of
other methods. Heat does not have a chance to build. Also, the unit is jacketed,
for proper temperature control.
LOWER INVESTMENT
FASTER PRODUCTION
LESS MANPOWER
ALL-IN-ONE TANK JOB
LESS HEAT BUILD UP
Single Daymax costs less than slow-speed mixers with three-roll-mills.
Batch compounded under high shear drastically reduces batch times.
No milling personnel needed. Larger Batchs means less manpower/Ton
Higher Yields,2-3% higher. Easier Clean
Dispersion is accomplished so rapidly that heat does not build up.
