A new protective coating by 3M is designed to help prevent damage to turbine output caused by erosion on the leading edge of wind blades.

Wind Blade Protection Coating W4600 is a two-component polyurethane coating that provides erosion protection properties to help prevent and repair edge errosion on wind blades.

"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," 3M said in a product announcement. "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's Renewable Energy Division introduced the coating at WINDPOWER, which took place May 5-8 in Chicago, IL.

3M expanded its line of wind blade protection products with a polyurethane coating.

The coating further expands 3M's wind blade erosion protection portfolio, which also includes blade protection tape.

The product is designed for application in OEM facilities and can be applied with a brush or casting, the company said.

"3M has performed extensive testing on this product, and customers will see that it provides superior performance for a critical industry need," said Christian Claus, business development manager, 3M Renewable Energy Division.

3M manufactures products for a wide range of industries. The company employs approximately 88,000 worldwide with operations in more than 70 countries.
