for silica and wax treated silica matting agents in UV coatings. According
to the company, coatings formulated
with Solsperse 71000 have lower overall gloss and better matting reproduc-tivity. Solsperse 71000 joins Noveon’s
established line of additives for UV
coatings including Solsperse 41000,
which is used for reducing the viscosity of silica and inorganic pigment dispersion; Solsperse 36000, designed for
dispersing and stabilizing TiO2; and
Solsperse 39000, a dispersent for carbon black and organic pigments in UV-cured coatings. All Solsperse hyperdis-persants designed for UV-cured applications are 100% active.
BASF has recently made several
additions to its Laromer portfolio of
resource-saving, emission-free radiation curing products. Laromer UA 9033
V is designed for high flexibility applications such as coil coating in which 0-
T bends are required. Laromer PO
9026 V is designed for resistance to
micro-scratching, preventing loss in
gloss due to fine scratching or marring.
Laromer PE 9024 V is designed for
compatibility with nitrocellulose and
systems that incorporate UV with conventional coatings. Lastly, Laromer PA
9030 V is designed for adhesion to different metal types such as aluminum
and polished CRS.
“One of the emerging industry
trends is expansion into tradition, non-
radiation cured coatings applictions
such as three-dimensional objects,”
said Werner Peter, business director,
performance chemicals for coatings,
plastics and specialties, for BASF in
North America. “BASF’s Larolux UV
curing method enables three-dimensional objects to be cured without the
use of expensive, high powered lamps.
It is based on an inert atmosphere of
carbon dioxide. The carbon dioxide is
contained in a chamber that is lined
with brushed aluminum that is used
as the reflector.”
Most recently, Clariant has introduced Ceridust TP 5091 and TP
Ceridust 5851R, which are micronized
UV reactive waxes for the improvement of slip, scratch and chemical
resistance and matting of a given UV-cured formulation. In addition, the
company offers a number of organic
pigments and dispersions which can be
used for coloration of radcure coatings
for wood and powder applications
among others. Clariant has also added
Sanduvor TB-02 liquid, a UV and
HALS blend suitable for UV curable
coatings to its portfolio.
Equipment suppliers are also making strides in technologies to improve
successful curing of 3D parts.
Henkel Corporation has introduced
the Loctite 7700-HD LED Light Source,
a high-powered, portable curing system
for UV and visible light curing adhe-
sives. Equipped with an internal cooling
fan, this hand-held or stationary mount
system provides effective continuous
duty cycle use, according to the company.
The Loctite 7700-HD features a patent
pending LED technology that eliminates substrate heating, and offers a typical output of
1.0 to 1.5 W/cm2 at a peak wavelength of
405 nm. Powered from an AC power adapter,
the system requires no batteries.
RADTECH’S UV.EB WEST 2007 IS MARCH 6-7 IN LOS ANGELES
Following up on the success of e| 5, RadTech has recently announced
dates for uv.eb West 2007, which will be held March 6-7 at the Sheraton
Gateway Hotel at LAX in Los Angeles.
Presentations and demonstrations by leading industry suppliers and
users will target the environmental, economic, energy savings and performance benefits of UV and EB and how the technology enables manufacturers to meet and exceed regulatory requirements.
uv.eb West 2007 will include a tabletop exhibit and conference program covering the basics of UV and EB technology. In addition, application workshops on aerospace and defense, UV inkjet, wood
finishing/building materials, composites, adhesives, electronics, commercial printing/converting, metal, plastics finishing are planned.
Complete session and registration information is available online at
www.uvebwest.com. To request a complete uv.eb West 2007 registration
brochure or to obtain information on exhibiting call RadTech
International, 240-497-1243; Fax: 240-209-2337.
The high-powered LED light source
features an extended tip that is ideal
for use on small adhesive joints. Sized
at just 9 x 1.4 x 2-inches and weighing
just 0.75 pound, the Loctite 7700-HD
may be actuated using a foot switch,
PLC interface cable, or timer. The LED
light source operates effectively up to
five times longer than typical UV
bulbs, the company said.
Earlier this year, Nordson Corporation
introduced its Light Tite shutter system,
which instantly opens and closes to block
UV light for accurate control during curing operations and was designed for use
with the company’s CoolWave system.
Added to each CoolWave system lamp
head, the pneumatically powered
LightTite shutter opens and closes
intstantly, without turning off the lamp
head and power supply.
The AirShield ventilation system is
another new product from Nordson for
use with the CoolWave system. The
AirShield ventilation system provides
the user with the means to capture the
hot exhaust air from the lamphead and
remove it easily from the cure zone,
which eliminates any possible contamination issues in curing applications. CW
