Hexion To Introduce New Products for Wind Energy Rotor Blade Manufacturing At JEC

COLUMBUS, Ohio–(BUSINESS WIRE)–Hexion Inc. (“Hexion” or the “Company”) is introducing a new tackifying
spray system as well as new epoxy bonding paste and resin repair kits
for use in rotor blade maintenance, all with enhanced environmental and
performance characteristics, at the JEC World international composites
exposition, March 6 to 8 in Paris. In addition, the company will
showcase its new, large volume Hexi-BagTM packaging system,
as well as its industry-leading epoxy resin systems for the wind energy
market.

“For over 40 years, since the first composite wind blades were
developed, Hexion has been collaborating with customers to develop
innovative materials that result in more robust part designs and greater
overall efficiency,” says Ann Frederix, Senior Vice President, Epoxy
Specialties. “Our newest products help our customers reduce costs while
enhancing blade performance and improving processing.”

New Sticky-SprayTM System
Enhances Production, Improves Workplace Safety

Hexion’s new epoxy-based Sticky-Spray system, PR687g, can be used as a
replacement for traditional aerosol spray systems in the fixation of
fiberglass root plies in blade manufacturing. Unlike existing
solvent-based solutions, the sticky spray contains no aerosols or
solvents, reducing in-plant air emissions. It also chemically reacts
into the epoxy matrix after infusion.

Using the Sticky-Spray system to securely fix the glass reinforcements
in a resin mold avoids weakening the fiber matrix interface through
incompatible components which can adversely affect the mechanical
properties of the resulting composite. The Sticky-Spray system can be
used with conventional application equipment and comes in various
packaging types depending on customer requirements.

New HLU 635 Epoxy Repair Kit for Blade Repair Reduces GHS Hazard
Labeling

For rotor blade repairs, Hexion is introducing a new epoxy resin repair
kit for hand lay-up that provides superior performance properties while
minimizing GHS hazard labeling (Globally Harmonized System of
Classification and Labeling of Chemicals). Due to its formulation, the
new laminating resin system, HLU 635 eliminates human toxicity and
Health Hazard labeling and does not contain any ingredients on the REACH
candidate list of “substances of very high concern.”

The HLU 635 repair system offers excellent mechanical performance. It
does not become brittle at room temperature, resists crystallization,
and the cure rate can be adjusted variably for better workability. It is
available in two packages: 450g for use in a standard cartridge with
static mixer and 300g in 2k bags.

The Paste 20 adhesive repair system will also be featured in the Hexion
booth. Paste 20 is a toughened adhesive for “drill and fill” repair
applications such as voids in bond lines as well as in T-bolt
applications to improve bearing strength. Paste 20 offers excellent
adhesion, even on cured epoxy surfaces as well as in composite-to-metal
and composite-to-other substrate applications. It is GL approved and
comes in SBS cartridges as well as a novel 2k concept package.

Hexi-Bag™ Packaging System Provides Resin in Large Volume
Packaging, Reduces Transport Costs

Also at the show, Hexion will showcase its Hexi-Bag packaging system, a
new large volume resin package designed specifically for the wind energy
industry.

The new packaging format was developed for Hexion’s epoxy resins and
associated hardeners and provides wind blade manufacturers with several
efficiencies and cost advantages. The Hexi-Bag packaging has a capacity
of 900-1,000 liters, which is approximately five times larger than the
standard drum, addressing the large volumes of resin required to produce
rotor blades. In addition, use of the Hexi-Bag packaging reduces
residual material in the packaging to less than one percent, versus the
5-10 percent waste associated with traditional packaging. Use of the
Hexi-Bag system can result in reduced internal shipping costs of up to
80 percent as compared to standard packaging.

Industry-Leading Epoxy Resin Systems Provide Strength and
Durability in Large Rotor Blades

With more than 40 years of experience serving the wind energy market,
Hexion is a recognized leader in providing resin systems and allied
products for rotor blade manufacturing. The latest advances in Hexion’s
leading-edge EPIKOTETM resin systems and EPIKURETM
curing agents, which provide outstanding strength and fatigue
performance in today’s larger, heavier rotor blades, will be showcased
at the exhibition.
