Vibrating surfaces are often dampened by
applying visco-elastic materials directly to the
surface, thus converting the vibration energy to
heat. The flexing of the damping material
provides the energy dissipation and “decay” to
reduce noise. Metal no longer “rings” when it is
struck or excited by airborne noise.
Color:
Light beige, non-reflective stipple finish.
Density:
85.3 lb./cu. ft (wet), 72.9 lb./cu. ft.
(dry), 350 pentrometer viscosity at 80°F.
Sprayable loose paste.
Sanitation:
All components have FDA approval. Vermin
resistant. Chemical Resistivity:
Resists dilute acids, alkalies, grease,
gasoline, aliphatic oils. Dried coating will
soften with prolonged soaking in water, but will
recover after subsequent drying. |

-
Base material should be free of grease, oil,
dirt, scale and moisture. Wire Brushing is
recommended.
-
Adhesion is greatly improved on unfinished
metal surfaces if zinc chromate or red oxide
primer is applied first.
-
Can be applied by high pressure pump airless
spray equipment. (Recommended pump ratios
are 20:1, 30:1, and 40:1. Maximum tip size:
0.045 inch.)
-
Maximum application thickness per layer:
9/64” wet, which dries hard in 24 hrs. @
77°F. A 1/32” layer dries hard in 4 hrs. @
77°F, or can be dried in 5 min. at 220°F.
Effectiveness: Recommended coverage will
result in damping ratio of at least 50 dB per
second at 60°F. Specific performance may be
affected by geometric configurations and,
therefore, should be determined empirically. |
