GTMat Onyx Specifications

- GTMAT ONYX Sound Deadener is a self-adhesive insulator coating that consists of a black buytle rubberized compound laminated to a protective layer of aluminum. The product is produced in sheets and comes with polymer film release layer that is removed upon application.

- GTMAT ONYX Sound Deadener adheres to almost any surface instantly, and is pressure sensitive. The harder the pressure of application, the stickier the bond. Clean, grease-free surfaces provide the most durable applications. In general, the warmer the temperature, the tackier and more pliable the adhesive will be when handling and applying. Recommended application room temperature is between 50°F to+120°F (10C to 50C).

- GTMAT ONYX Sound Deadener has a superior temperature adhesion range that is much higher than the leading discount deadener or hardware store variety products. Consider this feature when using a sound insulator in hot weather, or in heated automotive areas such as hood or firewall - You definitely do not want to use a mat that does not stick!

- GTMAT ONYX Sound Deadener is an extremely durable product. Rated at 20 years fail-free for exterior use, this product will deliver a lifetime of service in your automobile. GTMAT is water, oil, solvent, salt, rust, and heat resistant.

How does GTMAT ONYX Work?

GTMAT ONYX Sound Deadener is the perfect automotive sound insulation. The rubberized compound absorbs sound energy reducing distortion noise and eliminating panel rattle. Additionally, GTMAT adds mass to all applied panels, thus lowering the audible vibration resonance.

Just one layer of GTMAT ONYX sound dampener will reduce up to 5 DB of unwanted noise, thus making your ride sound quieter, and your stereo sound sublime! Because GTMAT is easy to apply, is permanent, creates no mess, and half the price of the leading brand, it is the obvious choice when choosing a sound dampening solution! Order GTMAT today, install it tomorrow, and finally hear what everyone has been talking about!
