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 loss.

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.

The decay rate at 60°F (16°C) is 48.3 decibels per second at 0.50 lbs./sq. ft. (2.5 kg/sq. m) dry when tested according to Geiger-Hamme Thick Plate Method.
Kinetics Damping Compound Model KDC-E-162 shall consist of a visoelastic latex emulsion (vinyl base) vibration damping material for application on noise radiating surfaces to reduce the ringing noise due to shock or vibration to a deadened sound.
Model KDC-E-162 shall be non-asphaltic in nature, non-bleeding, and non-odor producing. When applied to a 10″ x 10″ x .035″ (254 mm x 254 mm x 889 micron) panel of primed cold rolled steel at the rate of 0.5 lb/sq. ft. (2.5kg/sq. m) (dry weight) the material shall show no loss of adhesion when subjected to two 25 inch-pound (0.29 kg-M) impacts from a two inch (51 mm) diameter, 1-1/2 lb. (0.68 kg) steel ball at -20°F (-29°C).
When tested under ASTM Specification E-162, Model KDC-E-162 shall have a Flame Spread Index, IS of 0.59, and a Smoke Generation Mg of 0.1, and shall be termed as Fire Retardant under ASTM-D635-63 (will not support combustion) and be termed non-hazardous and non-toxic.
Damping efficiency shall be measured by the Geiger-Hamme Thick Plate Test Method, with a 48 dB per sec. decay rate at 60°F (16°C).
Damping Compound shall be Kinetics Model KDC-E-162 as supplied by Kinetics Noise Control, Inc.
