BASF launches pigments for auto coatings
BASF has launched a number of
new pigments for automotive coatings.
Paliocrom Brilliant Gold is the newest effect pigment in the Paliocrom Brilliant
product family. Due to its high chroma
and lightness, Paliocrom Brilliant Gold enables designers to create eye-catching effects, according to the company. Paliocrom
Brilliant Gold’s performance makes it specially recommended for use in high-quality
automotive finishes, industrial paints and
coatings for computers, communications
devices and consumer goods.
Lumina Royal Blue is a new intense red-shade blue interference pigment, which allows reduced amounts of pigment in
standard effect shades, thereby improving
the physical properties of the coating without sacrificing the overall interference effect.
Lumina Royal Blue is the first high-chro-maticity effect pigment being launched as
part of BASF’s extension to the Lumina effect pigment portfolio. This new effect pigment offers the highest color strength,
brightness, brilliancy and chromaticity of
any blue pigment currently available, the
company said.
Heliogen Blue L 6600 F is the latest development in blue Heliogen pigments. Heliogen Blue L 6600 F is a Pigment Blue 15: 6
copper phthalocyanine blue pigment with
enhanced coloristic performance and excellent secondary properties. Its color strength
leads to improved economy in application
in that less pigment is needed, which leads
to higher cost effectiveness. The pigment is
a member of the “neutral flop” blue series.
The neutral color flop allows styling trends
with limited color shift when viewed from
different angels.
Evonik launches Aerodisp WR
8520 waterborne dispersion
Evonik Industries has launched Aerodisp
WR 8520 waterborne dispersion based
on hydrophobic, or water-repellent, silica. Coatings based on this dispersion
can be formulated for improved corrosion resistance. Aerodisp WR 8520 improves rheology control and anti-settling
behavior and pigment stabilization in
coatings, according to the company.
Aerodisp WR 8520 dispersions allow
dust-free handling of Aerosil silica powder in liquid media. They are ready to use
and easy to handle.
Union Process develops
cryogenic grinding system
Union Process has developed a system for
controlling the flow of liquid nitrogen into
the grinding chamber for customers performing cryogenic grinding. The engineered system includes a probe inside the
grinding chamber that monitors the temperature, and at the same time, regulates
the flow of liquid nitrogen into the mill to
maintain the desired temperature. Raising
and lowering the temperature is accomplished by adjusting the dial up or down.
The device is then able to change the rate
of flow of liquid nitrogen into the chamber to achieve this goal. The system was
designed for use with Union Process 01-
HD and 1-S Laboratory attritors, however, the system can also be adapted for
use with production-sized mills.
Falcon Technologies launches
ColourFal Zero VOC-free
universal colorants
Falcon Technologies Inc. has launched
ColourFal Zero VOC-free universal colorants. Designed for in-store point-of-sale
(POS) volumetric color dispensing machines and volumetric in-plant tinting,
ColourFal Zero is VOC-free, alkylphenol
ethoxylate-free (APE/APEO), low odor
and contains no free-formaldehyde or
formaldehyde donors. With ColourFal
Zero, sustainability is built into the colorant design through the use of raw materials from renewable resources. Using a
patented technology called Smart Tint, this
chemistry optimizes flow and eliminates
dry out, preventing dripping and blockage
of the nozzle in POS dispensing machines,
according to the company. As a result,
ColourFal Zero can be used in both manual and automatic tintometric dispensing
machines. Developed for the global market ColourFal Zero colorants are universal and are compatible with both
waterborne and solventborne architec-
tural, decorative paints.
Michelman offers NatureShield
oil emulsions for wood stains
NatureShield is a new line of environmentally friendly, water-repellent additives for interior and exterior wood, stone and concrete
coatings from Michelman. All are emulsions
of natural oils and waxes that provide excellent water resistance and water beading
when used in coatings, stains and sealants,
according to the company. NatureShield 30
is an emulsion of tung oil that provides a
tough, highly water-resistant finish that does
not darken noticeably. It produces water
beading and hold out in exterior wood stains
and sealants, and is also used because of its
light golden tint. When used in coatings for
stone surfaces, it provides durability and a
desirable “wet” look when dry. NatureShield
31 is an anionic emulsion of natural oils and
waxes that provides water resistance and
water beading in topical wood coatings. It
helps prevent wood from swelling in the
presence of water, and is typically used in
wood stains and sealants. NatureShield 40
is a film-forming natural oil emulsion used
to provide water resistance inboth wood and
concrete coatings as well as moderate scratch
and mar resistance.
Keystone Aniline presents a
new non-VOC, small particle
size pigment dispersion line
Keystone Aniline has introduced a new
non-VOC, small particle size pigment dispersion line called NeroTint. Keystone
Nero Tint products are aqueous, non-VOC,
high performance pigment dispersions for
wood and concrete coatings. The Nero Tint
line has been engineered to provide excellent transparency, high gloss and uniform
color in both spray and wiping applications. These products are formulated with
high performance pigments, milled to very
fine standards for ease of wood penetration
and are exceptionally clean and transparent. Furthermore, they are made to be very
miscible in water systems. (Please note, EU
standards do not consider this a non-VOC
product. Please inquire with Keystone’s reg-ulatory department for details.) CW
