Dexdamp 423
/ SikaDamp 630 Automotive Soundproofing
$130.00 per box of 10
DexDamp 423/ SikaDamp 630 automotive soundproofing is an excellent
way to reduce road noise and vibration. Dexdamp 423
/SikaDamp 630 can
be applied too the the floor boards, headliner, trunk, door
panels or engine fire wall.
Note: Dexdamp 423 and
SikaDamp 630 are the same product under different
labels.
Dexdamp/SikaDamp is a pressure sensitive,
elastomeric constrained layer vibration damping
material. Put simply, it is a flexible, peel and stick
sheet which can be applied to a variety of surfaces to
reduce structure borne vibration and noise. The damping
material is covered with a thin aluminum foil
constraining layer which improves performance and
provides a paintable, finished surface.
SUPERIOR BONDING
Dexdamp/SikaDamp is without
question the stickiest damping sheet ever developed. It
was designed for the vehicle industry for production
line use. Believe it or not it will even bond to oily
metal! Ordinary film adhesives can fail if the bonding
surface is not perfectly clean, especially on vertical
surfaces. The peel strength of Dexdamp/SikaDamp easily outperforms
conventional felted asphalt dampers and does so at a
lower weight per-
unit area. The super adhesion and conformability of
Dexdamp/SikaDamp results in maximum surface contact, critical for
high performance damping.
Application Specifications
As a general rule, aluminum or plastic
substrates up to 1/4", or steel to 1/8" may be suitable
for Dexdamp / SikaDamp. Listed below are common damping situations.
VEHICLES
For road noise treat the floor plan, strut towers,
firewall, doors, trunk, roof and dash panels.
PIPES & TUBING
Use as a wrap for metal or plastic as used in
plumbing drains or hydraulic systems.
VEHICLE STEREO SYSTEMS
Audio system performance can be improved by treating
panels next to speakers or when used as part of a
speaker enclosure.
BOATS
May be used for bulkheads, decks, tanks, engine room
ventilation ducting, fiberglass exhaust silencers and
tubing.

Dexdamp 423 / SikaDamp® 630
Adhesion and Durability
Dexdamp 423 / SikaDamp® 630 has
demonstrated excellent adhesion to CRS, galvanized and
galvanneal steel, ELPO and basecoat and clearcoat body
panels. Its outstanding adhesive performance allows it
to maintain its position in the most demanding vertical
and inverted applications, even at elevated paint bake
temperatures. SikaDamp® 630 maintains its acoustic and
adhesive properties after subjection to the various bake
schedules and accelerated aging and weathering test
conditions used in the automotive industry.
Acoustic Performance
SikaDamp® 630 is a technologically
advanced formulation that offers superior damping
performance at a reduced weight over traditional mastic
constrained layer and asphaltic extensional dampers. The
damping performance is maintained from –10°C to 60°C
allowing use in any area of the vehicle.
