Model KDC-E-162 viscoelastic damping compound is used to reduce noise radiated
by vibration or shock excited metal surfaces and panels by imparting vibration
damping to metal or other hard non-metallic, shifting the peaks of the generated
sound by lowering the natural frequency, and increasing the sound transmission
Model KDC-E-162 Damping Compound has low flame spread and smoke generating
properties as tested under ASTM-D635-63 and ASTM-E-162 (see physical data),
and is resistant to most commonly used acids, alkalies, and solvents.
Model KDC-E-162 Damping Compound is easily troweled or air sprayed onto a
clean surface. Model KDC has a consistency equivalent to sprayable loose paste
and does not require extensive stirring or mixing or the addition of thickening
agents prior to its usage. Vertical surfaces can be sprayed a thickness of
1/8" (3 mm) with no sagging or slumping. Adhesion is excellent on clean metal
as well as on hard non-metallic surfaces.
When sprayed, Model KDC-E-162 provides a tough, flexible, attractive, and
non-abrasive stipple effect having a light tan finish. For outdoor applications,
the damping compound can be painted with enamel or epoxy-type paints for color
matching or to provide additional protection.
Kinetics Damping Compound Model KDC-E-162 is suitable for use in a wide variety
of applications where it is intended to damp or eliminate the ringing noise
caused by vibrating or shock excited metal and hard non-metallic surfaces.
Model KDC also is recommended for use in architectural and mechanical equipment
applications such as treating of ducts, mixing boxes, sound-proof doors, and
metal partitions in the new construction field where it is mandatory to use
non-combustible or non-smoke generating materials to meet local fire codes
Spray application of Model KDC-E-162 provides an attractive stippled appearance
while at the same time decreases the radiated noise level due to vibration
or shock excitation and increases the sound transmission loss of the treated
material. The damping compound can also be troweled onto the surface to be
