Before spraying, make sure the area to be covered is
free of rust, dust, oil and any foreign material. The surface should
be totally dry. Cover or mask off any adjacent areas that should not
be sprayed. You can apply Dynashield with a brush, roller or compressed
air gun (the Dynamic Control spray gun item #10025 is recommended).
Total thickness of the finished coating should be 1.5 to 2.0 mm or .050"
to .125" (1/16" to 1/8"), approximately the thickness
of a small coin. You may apply two to three coats; allow one hour between
each coat. Dynashield forms a skin in 10 to 20 minutes, sets in one
hour and is totally cured in 12 to 36 hours. Times vary according to
ambient humidity and application thickness.
Paintable: To paint Dynashield, no sanding,
top coat or sealing is necessary.
Cleanup: Flush wet overspray with water and
wipe with a soft cloth; Dynashield is not abrasive. Rinse tools and
sprayers completely with water.
Thinning: If desired, you can reduce Dynashield
with water, using the following formula: 2.5oz. per gallon or 20ml per
liter. Do not exceed 2% of volume with water.
Chemical Resistance: Water and Chemical Resistant when cured
Handling and Application: Material must have reached room temperature before handling.
Fire Classification: Non-Flammable, non-combustible
Acoustic Loss Factor @ Temperature (Using ASTM method
E756 @ 200 Hz): Available on request
Temperature Resistance Range When Dry: -30ºF to 250ºF

Description
Dynashield is a unique liquid sound
control product that performs like a resonance and vibration control
material. Its 5-in-1 formula is optimized for use as a Sound Deadener,
Undercoat, Gravel Guard, Rust Protector and Thermal Shield.
Dynashield is a waterborne visco-elastic polymer compound that sprays
on for a "high build," drying to a smooth, flat black
finish to give a cosmetically integrated look either inside or outside
the vehicle.

Acoustic Properties
The acoustic loss factor "n"
is used as a measure of a material's ability to damp structure-borne
sound by stating how much vibrational energy (in steel sheets for
instance) is converted to heat rather than sound. For constructions
containing several layers of damping material, the combined loss
factor "n comb" is used. The theoretical maximum loss
factor is 1 (no vibration). An undamped 1mm thick steel panel has
a loss factor of roughly 0.001 at 200 Hz. Damped with Dynashield,
the loss factor would be about 0.063 at +0°C (32°F), 0.079 at +15°C,
and 0.076 at +30°C. Multiple applications of Dynashield improve
sound damping even more.

Applications
Dynashield is a sprayable product
for easy application in doors, corners, crevices and other hard-to-reach
places, including the vehicle's undercarriage. Dynashield also works
well on fiberglass enclosures to strengthen the whole enclosure.
