Momentive Sells NXT Z* Silanes in United States

Momentive Performance Materials today announced that its NXT Z*
family of silanes is now commercially available in the United States.
Excellent products to consider for ease of manufacturing and possible
reduction of production cost for silica tires, NXT Z silanes may
virtually eliminate ethanol emissions and help produce higher
performing silica tires. NXT Z silanes have been formally registered
on the US Toxic Substances Control Act (TSCA) list and registration is
underway globally, including in Europe, Canada, China, Australia and
Japan.

Momentive's newest coupling agents for silica tires, NXT Z silanes
are essentially ethanol free and offer the potential for one-pass
mixing and shelf-stable silica compounds for which the NXT* family is
known. Excellent candidates to enhance the wear, traction and rolling
resistance properties of silica tires while dramatically reducing
emissions, four NXT Z silanes are currently available in the United
States: NXT Z 30 silane, NXT Z 45 silane, NXT Z 60 silane and NXT Z
100 silane. Momentive will also offer these four silanes in powder
form, carried on carbon black.

"NXT Z silanes represent a groundbreaking advancement for
manufacturers of silica tires, underscoring our commitment to helping
our customers meet their most challenging performance objectives with
outstanding new science and research," said Mike Stout, global
marketing manager, Momentive. "NXT Z silanes may help control silica
tire production costs and meet increasingly stringent environmental
requirements, and also allow for improved wear, traction, tire life
and overall product performance. We are very pleased to be able to
offer NXT Z silanes to our US customers, and, in the near future, we
expect to expand commercial availability globally."
