Overview

Built for the booth.

A non-shrinking formula used to reduce noise, flutter, and vibration between intrusion beams and braces to body panels.

DURAMIX 1450 NVH Dampening Material is a professional-grade vibration and noise control solution designed for automotive body panel applications. This 7 oz. aerosol product provides effective dampening properties to reduce unwanted vibrations, rattles, and road noise in vehicle panels and enclosed spaces.

The material features a convenient 1:1 mix ratio and achieves full cure in 24 hours for efficient workflow planning. It bonds effectively to multiple substrates including aluminum, bare metal, e-coat, OEM finishes, and primer surfaces, making it versatile for various repair scenarios. The aerosol delivery system ensures consistent application and coverage in hard-to-reach areas where traditional dampening materials may be difficult to install.

Apply in a well-ventilated area and follow standard spray application safety protocols including appropriate respiratory protection and eye protection when using this product.
