Proper sealing and flexible-yet-durable bonding is critical in many wind applications. Moisture, chemicals, extreme temperatures and UV light can eventually degrade even the strongest composites.

From polyurethanes to advanced hybrids, 3M™ Wind Sealants can be used for virtually any application in the wind industry. And 3M's smart packaging technologies keep moisture out and maintain product quality long-term—all while making application simple, economical and fast.
