Troy introduces Mergal 753
wet-state preservative in Canada
Troy Corporation announced that The
Pest Management Regulatory Agency of
Health Canada, in accordance with the
Pest Control Products Act, has approved
the usage of Mergal 753 wet-state preservative for the in-package protection of
paints, coatings and allied products. Mergal 753 is a zero-VOC, formaldehyde-free
dispersion with broad-spectrum efficacy
against bacteria, fungi, and yeast, which
cause deterioration of aqueous systems.
Mergal 753 is the highest concentrated
product of its kind with free-flowing characteristics and a uniform homogenous nature. Additionally, Mergal 753 has a low
toxicity profile and contains no alkylphe-nol-ethoxylates (APEs). As a high-performing preservative concentrate, Mergal
753 provides effective in-package microbial protection using less total volume per
product batch compared with all other
technologies, according to the company.
Cabot launches new insulating
coatings additive
Cabot Corporation recently introduced
Enova aerogel, a new high performance
thermal additive designed specifically for
insulation coatings. Cabot researchers
have found that applying a 1mm coating
containing Enova aerogel to a 200°C
metal surface meets U.S. and European
testing protocols for safe touch temperature, preventing the first-degree burns one
would normally expect within five seconds
of skin contact. This not only protects employees, but also helps keep the pipe contents at desired temperature. Coatings
containing Enova aerogel can also be used
to insulate cold surfaces helping to eliminate freezer burns and to reduce the power
requirements needed to keep contents
cold. Enova aerogel is designed for application to surfaces that are not already insulated but ideally should be. This includes
hard to reach and expansive areas of exposed metal where traditional insulation
methods cannot be used due to limited access, size or shape. Enova aerogel can be
added during formulation or on site and
does not adversely affect the viscosity of
the coating enabling it to be applied easily
to a surface. Cabot’s Enova product line is
made up of aerogel and each particle consists of more than 90 percent air trapped
within a network of amorphous silica
making it twice as insulating as still air.
The low thermal conductivity of Enova
aerogel – 12 m W/mK – works better than
traditional insulation such as polyurethane
foam (typically 30 m W/mK) and additives
such as glass or ceramic microspheres, according to the company.
Eastman launches Solus
performance additive for
waterborne coatings systems
Eastman Chemical Company has introduced its newest Solus performance additive, Solus 3050, specifically engineered to
help formulators meet VOC, performance
and productivity goals in waterborne coatings systems. Derived from natural and renewable cellulose material, Solus 3050 can
be used in the automotive, industrial metal
and consumer electronics coatings markets. Performance benefits include
smoother finish, optimal metallic flake
control, better redissolve/strike-in resistance, superior flow and leveling, improved
atomization, and greater adhesion to galvanized steel, according to the company.
Solus 3050 also enables faster dry time
and early hardness, application consistency over varying climatic conditions, improved wetting, increased sag resistance,
and it enhances flexibility in aluminum
flake selection.
Cytec launches Ebecryl 8100 UV
curable modified urethane
acrylate
Cytec Industries Inc. has introduced a newly
developed urethane acrylate for consumer
electronics. Ebecryl 8100 is designed to meet
the growing demand for easily cleanable
protective coatings for tactile screens. It
combines easy-to-clean properties with best-
in-class surface protection for functional
and decorative coatings. Once cured by UV
light, Ebecryl 8100 creates a very tight polymeric network with a contact angle of approximately 115o (water) that withstands
cleaning and abrasion tests and carries a
long lasting easy-to-clean effect.
Gelest updates Hydrophobicity,
Hydrophilicity and Silane
Surface Modification brochure
Gelest, Inc. has updated its Hydrophobicity, Hydrophilicity and Silane Surface
Modification brochure. This new publication includes new functional materials, including silanes with embedded polarity,
biomimetic activity and fluorescence. The
brochure contains a description of nonfunctional silane monomers and siloxane
oligomers used to render surfaces hydrophobic or hydrophilic. The emphasis of
this 80-page updated publication is on distinguishing the features and benefits of the
entire range of commercial alkyl-silanes
and aryl-silanes, including dipodal PEG
and fluorinated materials for use as water-repellents, release coatings, architectural
coatings, pigment dispersants, mineral surface treatments and anti-stiction, optical,
dielectric, biomimetic, fluorescent coatings.
It also includes comprehensive information
on how to apply materials to achieve desired performance.
Elementis launches Rheolate
299 for aqueous industrial
coatings market
Elementis Specialties has introduced Rheolate 299 for the European decorative and
aqueous industrial coatings markets. This
new rheology modifier is designed for waterborne industrial and decorative, pigmented and clear, gloss and high gloss
coating systems. It provides strong shear
thinning behavior, which makes it ideal
for spray applications including sprayed
latex emulsions, dispersions, water re-ducible clear-coats and high gloss pigmented systems, the company said. CW
