Kinetics KDD-3642 Sound Deadener consists of a bituminous sheet damping material designed for cost effective vibration damping. KDD-3642 Sound Deadening Sheets effectively reduces the resonant vibration of sheet metal panels that radiate noise. It also reduces the loudness and duration caused by random impact noises when panels are struck. The material is rated self extinguishing, is black in color, is available in 36" x 42" x 0.060" and weighs 0.579 PSF. The material can be slit, punched, or die cut into parts to meet the customer’s specifications.
Model KDD-3642 contains a pressure-sensitive adhesive on one side which is protected by an easily strippable release liner. The adhesive is a high performance acrylic adhesive which exhibits high tack for easy installation resulting in 100% contact for maximum damping effectiveness.
KDD-3642 Sound Deadener is suitable in a wide variety of applications where it is intended to damp or eliminate the "tinniness" type noise caused by vibrating metal surfaces and panels. The KDD-3642 Sound Deadener should be applied to a clean dry surface at room temperature with a hand roller to ensure even pressure. Firm even pressure is required to bond damper to substrate. Before application the product should be staged at temperature higher than 50°F for not less than 3 hours.
