NVH DAMPING MATERIAL - 3M Automotive

The 3M Automotive NVH Damping Material, Model 4274, is a professional-grade, two-part urethane solution expertly engineered for precise control of noise, vibration, and harshness (NVH) in automotive and industrial environments. This specialized material allows technicians to effectively reduce unwanted sound and vibration, contributing to enhanced perceived quality and comfort of repaired or manufactured components.

Key Features

• Targeted NVH Control: Specifically formulated to address localized noise and vibration issues within various systems and structures, improving overall acoustic quietness and a refined finish.
• Optimal 60-Minute Work Time: Provides professional technicians with a generous work time, facilitating accurate installation and precise placement to minimize rework.
• Non-Shrink, Durable Composition: This soft, sturdy, non-solvent urethane formula effectively dampens vibration without shrinking after installation, ensuring consistent performance and long-term durability.
• Versatile Application: Ideal for filling thin gaps where traditional foam materials are challenging to apply, and capable of application up to 1 inch thick on vertical and overhead surfaces with minimal sag or drip.

Applications

The 3M 4274 NVH Damping Material is primarily utilized in automotive collision repair and for resolving specific noise and vibration concerns. Professional technicians commonly apply this 3M Automotive NVH Damping Material to reduce unwanted resonances and structural vibrations within vehicle components such as doors, roof skins, floor pans, trunk cavities, quarter panels, and door intrusion beams, effectively contributing to overall vehicle interior noise reduction. Its precise formulation also makes it suitable for intricate industrial applications requiring localized vibration control on machinery or equipment, including aerospace, marine, and agricultural equipment.
