  • Self-adhesive insulator coating consisting of a black buytle rubberized compound laminated to a protective layer of aluminum with polymer film release layer that is removed upon application.
  • Adheres to almost any clean, grease-free surface instantly, and is pressure sensitive. The harder the pressure of application, the stickier the bond. Recommended application room temperature is between 50 Degrees F to+120 Degrees F (10C to 50C). Application in warmer temperatures renders a tackier, pliable mat.
  • Superior temperature adhesion range, 400°F. Consider this feature when using a sound insulator in hot weather, or in heated automotive areas such as hood or firewall.
