New Ross Double Planetary Mixer
with Special Finger Blades
Charles Ross and Son has introduced a
new agitator blade design for their line of
Double Planetary Mixers. It is a 100-gal-
lon model equipped with two identical
rectangular stirrers with upward rake fingers. Designed to rotate on their own axes
while orbiting the vessel on a common
axis, these style blades are ideal for batching dry powder blends, wet granulations
and similar formulations in the Double
Planetary Mixer. Interchangeable helical
blades are available as options and allow
the mixer to be utilized for viscous pastes
and putty-like materials.
Speed, power load and cycle time are all
controlled and displayed from this screen.
Two-hand raise/lower controls for the air/oil
hydraulic lift are also located on the panel
for opening and closing the mixer. With the
blades in the fully raised position, they are
completely accessible for easy cleaning while
the portable mix can is removed from under
the mixer and rolled into the discharging
area. The vessel is supplied with lift trunnions so it can be raised and tilted for fast
transfer of the finished product.
Maintenance and risk of product contamination are very low in a Double
Planetary Mixer as there are no shaft seals,
bearings, packing glands and stuffing boxes
submerged in the product zone. Available in
both industrial and sanitary configurations,
the Double Planetary Mixer is built from
half-pint to 750-gallon capacities.
Clariant Launches POS
Color Dispenser Machines
Clariant has launched the first compact
color dispenser to allow simultaneous
dispensing of up to six colors at a time.
Clariant’s machine is one of two new innovative prototypes offering performance
and productivity benefits to retailers, according to the company. Clariant Color
Dispenser IQ-S16 is one of the most compact machines now available on the market with simultaneous colorant dispensing
mode. With a footprint of 0.53m³, it saves
on shop space without losing performance
and accuracy, according to the company.
Clariant’s dispensing technology allows a
dispensing speed of 1.1l/min with accuracy
down to 1/384 fl oz. It is based on stainless
steel piston pumps powered by a single motor that controls the entire system. The easy-to-use machine offers low cost operation
and ownership. It is virtually calibration free
and, as colorant is dispensed directly into
paint without the need for tubing, it keeps
maintenance time and costs to a minimum.
Color Dispenser CD3001 is designed
to serve the majority of paint stores which
are looking at design and good price. It
offers the same performance and productivity advantages as Clariant’s more compact model, the IQ-S16.
All Clariant machines are designed to
handle all kinds of low VOC water-based
and universal colorants to support the sustainability requirements of the paints industry. The fully automatic colorant dispensers
can be equipped with up to 16 easy-to-mount
canisters with a standard capacity of 3 liters
each, to match optimum refill cycles.
Evonik Introduces Dynapol
Terra, a Bio-based Binder
for Coil Coatings
Evonik Industries has developed a new
product range of polyester resins for coil
coating primers and topcoats to market
maturity under the established Dynapol
brand. Dynapol Terra is based on renewable raw materials, which sets it apart
from other binders used for this type of
coating, according to the firm. Most other binder systems are based on saturated,
hydroxyl functional polyester polyols
that are produced mainly from petro-leum-based raw materials. The colorants
and coatings industry has been looking
for suitable alternatives for these petrochemical building blocks for many years,
since resource efficiency is an important
growth generator.
With this new range of products, Evonik
has overcome two challenges at once, the
company stated. The coating experts
identified suitable bio-based polyester resin
building blocks and they ensured general applicability, fast implementation and
availability on an industrial scale. The first
Dynapol Terra polyester resins have already
been successfully introduced to customers.
Clariant Launches
Dispersogen PL 30/40
Clariant recently globally launched its
Dispersogen PL - range of dispersing agents
for waterborne pigment preparations.
Aimed at organic pigments and carbon blacks, the new dispersants give architectural coatings extra brightness and
brilliance – thanks to their high pigment
loading. The patented copolymers are
able to create dispersions with more than
50% pigment, significantly more than
conventional loadings, the company reported. And the Dispersogen PL – range
does this without sacrificing flowabil-ity. Viscosities of its pigment dispersions
are within the range of 50-500 mPAs.
Similarly loaded conventional pigment
preparations, by contrast, turn often to a
much higher viscosity.
According to Clariant, high pigment-loads also means that the Dispersogen PL –
range does more for less. Its typical mixing
ratio is 1: 10 up to 1: 5 dispersant based on
active matter to pigment, and customer trials
over the past two years have shown that the
pigment pastes have a very good shelf life,
stable against drying and very compatible
with all kind of waterborne coatings.
Dispersogen PL 30 and Dispersogen PL
40 additionally are safe to humans and the
environment. Dispersogen PL 30 as a nonionic copolymer and Dispersogen PL 40 as
an anionic copolymer have a friendly eco-tox profile and contain insignificant levels
of irritants and other hazards that might
require a coating to bear a CLP1 label.
Additionally these two dispersants have a
low VOC level and are suitable to be used
in decorative paints aiming to obtain eco-label certification such as Germany’s Blue
Angel (RAL-UZ 102). CW
