Description:
KDD-3553 Sound Deadener consists of filled asphaltic mastic acoustical sheet material designed for cost-effective vibration damping. Model KDD-3553 Sound Deadener 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 35" x 53" x .059" (889 mm x 1346 mm x 1.5 mm) and weighs 0.5 PSF (2.5 kg/m2). The material can be slit, punched, or diecut into parts to meet the customer’s specifications.
Model KDD-3553 contains a pressure-sensitive adhesive on one side which is protected by an easily strippable release liner. The adhesive is a high performance, permanent acrylic adhesive which exhibits high tack for easy installation resulting in 100% contact for maximum damping effectiveness. Maximum vibration reduction is achieved because the adhesive is an integral part of the sound deadener.
The adhesive will withstand temperatures up to 400°F (204°C) which permits passage through paint ovens without blistering or sliding down vertical surfaces.
Application:
KDD-3553 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.
Typical Applications:
- Bodies, doors, firewalls, and floors of trucks, buses, agricultural, and off-highway equipment.
- Metal office furniture
- Sinks, bathtubs, and shower stalls
- Air Conditioners
- Appliance cabinets
- Rapid transit or railway cars
- Recreational vehicles
- Chutes, bins, & hoppers
- Motor and transformer housings
- Machine housing belt guards
- Sheet metal ducts, mixing boxes, and terminal units
Physical Properties:
| Type: | Asphalt-based black |
| Thickness: | 0.059 ± 0.005 in. (1.5 ± 0.1 mm) |
| Weight: | 0.5 lbs./sq. ft. (2.5 kg/m2) |
| Standard Sheet Size: | 35 in. x 53 in. (889 mm x 1346 mm) or die-cut parts |
| Water Resistance: | Excellent |
| Solvent Resistance: | Most organic solvents will leach a small amount of asphalt from the sound deadener, but the sound deadener will not be damaged by occasional spillage of gasoline. Painting considerably improves resistance to gasoline and solvents. |
| Serviceable Temperature Range: | When applied to interior surfaces, the sound deadener will withstand temperatures up to +400°F (+204°C) without blistering or sliding down vertical surfaces. Although the sound deadener will embrittle at low temperatures, properly bonded parts will withstand slamming at -30°F (-34°C). |
| Flammability: | Self-extinguishing as defined by FMVSS 302. Also, recognized under the Component Program of Underwriters Laboratories, Inc. UL94HB. |
Specification:
KDD-3553 Sound Deadener shall consist of a heat-resistant, heat-bondable material composed of filled asphaltic mastic, coated with a pressure-sensitive adhesive on one side, protected by a release paper which is removed prior to installation. The release paper shall be double-coated to provide both release from the adhesive and blocking resistance in shipping and storage.
The material shall be furnished in sheets/die-cut parts having a black color, thickness of .059 ± .005" (1.5 ± 0.1 mm) and a weight of .5 Lbs. per sq. ft. (2.5 kg/m2).
Model KDD-3553 shall be free from flammable vapors, shall be self-extinguishing as defined by FMVSS302 and ASTM D 1692, and shall be recognized under the Component Program of Underwriters Laboratories, Inc. UL94HB.
The material shall provide excellent resistance to water and shall be capable of withstanding temperatures up to 400°F (204°C) without blistering or sliding down vertical surfaces. Properly bonded parts shall withstand vibration and repeated shocks (door slamming) at -30°F (-34°C).
Model KDD-3553 shall provide a combined loss factor at 250 Hz of .05 as measured at 70°F (21°C) on a 20 gauge steel panel.
Model KDD-3553 sheets/die-cut parts shall be provided by Kinetics Noise Control, Inc.
