ST. PAUL, Minn. -- May 6, 2013

Awareness is growing in the wind industry about the severe impact that erosion
on the leading edge of wind blades can have on turbine output. Erosion can
lead to a significant loss in annual energy production, costing owners and
operators thousands of dollars. Blade repair and protection can help provide
significant annual energy production improvements, reduce costly downtime, and
protect the integrity of the blade.

3M Renewable Energy Division is now introducing a new and innovative solution
for blade protection at WINDPOWER, May 5-8, 2013 in Chicago, Ill. 3M™ Wind
Blade Protection Coating W4600 is a two-component polyurethane coating that
provides excellent erosion protection properties to help prevent and repair
leading edge erosion on wind blades.

3M has a proven history of providing highly durable solutions in the industry
with its 3M™ Wind Blade Protection Tape. This product has provided significant
reductions in leading edge erosion, and has also helped extend maintenance and
service intervals. Designed to offer game-changing performance and protection,
3M Wind Blade Protection Coating W4600 further expands 3M’s portfolio of
erosion protection solutions. The coating is designed for application in OEM
facilities and can be easily applied via brush or casting.
