instrument to achieve high irradiance
levels of 120 W/m2 of total UV radiation.
By testing at higher irradiance levels, test
times can be significantly reduced, compared to standard weathering tests.
In addition to its high irradiance func-tionality, XenoLogic provides another
significant advantage: an extended lamp
service life. XenoLogic continuously synchronizes two 2200W xenon lamps inside the chamber at the lowest possible
stress level, which leads to optimized
lamp service life and maximized light
efficiency. With this new technology, the
two xenon lamps combined can last over
4000 hours under standard testing levels
of 40-60 W/m2. This increases instrument uptime and reduces lamp operating
costs by as much as 30 percent or more.
Allnex Unveils UCECOAT
7210 Waterborne UV
Resin to Produce Super
Hardcoats
Allnex recently introduced new
UCECOAT 7210 waterborne UV resin.
This product offers a wide blending
range with Allnex’s UCECOAT 7200
waterborne UV resin to produce super
hardcoats with tailor-made flexibility, according to the company.
Formulations based on UCECOAT
7210 and UCECOAT 7200 provide a
solvent-free, low viscosity UV hardcoat
with high solid content of approximately 65 percent and excellent stability.
Compared with solventborne systems,
this hardcoat demonstrates equivalent
mechanical and chemical resistance and
it also allows brand owners to meet sustainability requirements.
UCECOAT 7210 is recommended
as a co-resin with UCECOAT 7200 for
hardcoat on curved substrates where
flexibility of the coating is required such
as consumer electronic casings, automotive interiors, films and rigid plastics.
Union Process
Manufactures First Attritor
with Telescoping Head
Union Process, Inc. has produced its first
Attritor with a telescoping head. The
company custom-designed the special
telescoping head to facilitate maintenance
and access to the grinding tank. By rais-
ing the head assembly, the customer is
able to easily change out grinding tanks.
The cantilever designed telescoping head
was the first ever built by Union Process.
The SL- 30 batch production Attritor
will be used in an R&D application to
grind materials in liquid nitrogen. As
such, the mill includes a vented cover for
cryogenic grinding with liquid nitrogen
and a phase separator. A liquid nitrogen
controller is used to maintain liquid nitrogen levels during the milling process.
The product discharge is equipped with
a cryogenic ball valve.
The mill features a 304SS grinding
tank that is jacketed for cooling. The
agitator shaft is constructed of stainless
steel. Specially configured arms are 440C
stainless steel.
New Technical Brochure
Available from Orion
Engineered Carbons
A new technical brochure that explores
the benefits and performance properties
of NEROX 505 and Nerox 605 Carbon
Black pigments for industrial coatings is
now available for download from Orion
Engineered Carbons.
NEROX 505 and NEROX 605 pigments are suitable for both solvent- and
waterborne coatings systems, and offer
numerous advantages including stable
dispersion, high jetness and high bluish undertone. The four-page color brochure uses charts to highlight coloristic
properties in acrylic and alkyd-melamine
systems, relative tinting performance,
and jetness in water-based dispersions.
NEROX 605 shows superior jetness and
bluish undertones to NEROX 505 and a
competitive product.
According to the company, the Special
Furnace Blacks are produced using an
after-treatment process that leads to better wetting and dispersion properties and
lower oil and binder adsorption. This
in turn can mean better stability, higher
gloss and lower viscosity in water- and
solvent- borne coatings.

Charles Ross Offers
Turnkey Systems for
Accelerated High-viscosity
Mixing and Discharge
Charles Ross manufactures a range of
turnkey mixing and discharge stations
for batching paste-like materials and
high-viscosity formulations. The company’s Multi-Shaft Mixers, Planetary
Dispersers and Double Planetary Mixers
are all offered with an optional platen-style discharge system designed for non-flowable, sticky or heavy mixtures.
With push-button simplicity, the system automatically discharges a batch by
lowering a precisely-machined platen
into the vessel. An O-ring around the
platen rides against the vessel sidewalls
virtually wiping the surfaces clean.
Product is pushed out through the bottom of the vessel or through a port on
the platen.
The PowerMix features a saw-tooth
disperser blade and a planetary stirrer
which both revolve around the vessel
while turning on their own axes of rotation at independently-controlled speeds.
This agitator combination is ideal for
handling viscous dispersions up to approximately two million cP. After the
mixing cycle, the vessel is simply rolled
over to the discharge system. As the platen is lowered hydraulically into the vessel, finished product is forced out within
seconds. Various size and style adaptors
allow the operator to fill syringes and
cartridges straight from the mix vessel.
Yield is extremely maximized as normally only a thin layer of product remains on
the vessel bottom, the company reports.
Charles Ross also supplies turnkey
mixing and discharge packages for high-volume requirements. These systems
may include automatic feeders, metering
pumps, multiple vessels, clean-in-place
manifolds, filter assemblies, inline transmitters to measure viscosity, density, flow
rate, etc., pneumatically-operated valves,
integrated recipe controls and many others depending on the process requirements. Contact the company directly for
further information. CW
