Bayer MaterialScience launches two-component,
polyurethane waterborne technology for sealers
One of the fastest growing market segments in the concrete flooring arena is sealers for decorative and polished concrete
surfaces. There is a need in this market for
a more durable, longer lasting product said
Bayer MaterialScience LLC, which has developed a new technology for sealers.
Applicators want a product with
chemical and stain resistance, low odor,
long-term performance, ease of use and
concrete penetration. Bayer developed a
two-component (2K), polyurethane waterborne technology for sealers that offers
a number of advantages over currently
available concrete sealer products, including better ease of use; improved durability; low odor; increased service life; and
ultra-low volatile organic compounds
(below 15 grams per liter).
The various types of stained and polished flooring on which the sealer would
be applied are often found in commercial
and retail spaces, such as hotel lobbies and
restaurants. The technology is primarily
applied to indoor surfaces, but is also appropriate for outdoor applications.

Evonik Coating Additives
offers reference guide
Evonik has published a free reference
guide, “The Pocket Tego,” which contains
information to assist formulators in their
development of improved products for the
coatings and printing ink industries. The
144-page pocket-sized guide is a practical
tool that covers a comprehensive collection of topics including formulas, measurements and standards, color, raw
materials and typical coatings defects. In
addition to the reference materials, the
handy guide offers product recommendations formulators can use as a daily working tool for selecting the appropriate
additives, specialty resins and co-binder
for a wide variety of coating formulations.
Sulzer Mixpac offers
dispensing system innovations
for 2K materials
Sulzer Mixpac offers two-component
dispensing system technologies. The two
latest innovations include a two-component biopolymer cartridge and new dispensing systems for two-component
protective coatings in the area of corrosion protection.
Research and development at Sulzer Mixpac has been focused on its improving its carbon footprint. As a result the company has
produced a two-component cartridge that replaces a significant part of its plastic material
with wood fibers. With regard to leakproof-ness and diffusion properties, this cartridge fulfills the same criteria as the standard plastic
version said the company. However, it offers
the customer the
possibility to
differentiate by
a “greener”
value chain.
This serves the
trend towards a
purchasing decision process
which is increasingly influenced
by environmental friendly criteria. The 25 milliliter cartridge
is the first product from the Green Line product range while others are on the way.
With regards to repair and maintenance

sion protection of ships, pipelines and other
steel constructions, the work today is still performed manually for the most part using
brushes and rollers. These methods of application are time-consuming and create a high
percentage of waste
material, especially
when applied in
areas that are difficult to access.
Sulzer Mixpac’s
new MixCoat
Spray and MixCoat Flex coating
system with its new
spray technology
was designed to
save costs and reduce labor time
combined with
minimal waste of material. In addition, the
system also includes the advantages of the
Mixpac cartridge-based two-component
technology including clean storage of two-component materials as well as consistent
coating results said the company.

Huntsman launches epoxy
curing agent XTA-801
Huntsman has launched XTA-801, a highly
reactive fast cure cycloaliphatic amine used at
low and ambient temperatures. Developed as
a potential alternative to IPDA (isophorone
diamine) and 1,3-BAC (1, 3 bis-aminomethyl
cyclohexane). With a gel time of 47 minutes in
DGEBA standard liquid epoxy resin, XTA-
801 can be used alone or blended with other
epoxy curing agents e.g. JEFFAMINE D230.
Adding XTA-801 will increase glass transition temperature and decrease elongation and
impact strength; the resulting system will produce a cured epoxy with properties between
the XTA-801 and the other epoxy curative.
XTA-801 key benefits are highly reactive, fast curing at low and ambient temperatures; fast strength development;
enhanced glass transition temperature,
hardness and elastic modulus and good
chemical and solvent resistance. CW
