Application Techniques The tape should always beapplied to a clean drysurface. All edges must befirmly pressed down. Thepolyethylene liner eliminateswrinkles on unwind thusimproving the smoothnessof the tape on applicationand its handlingcharacteristics.

Tape can be applied downto -20°C but poor results willoccur below 5°C unlessspecial precautions aretaken to eliminate the thinfilm of condensed moisturefound on surfaces at suchtemperatures.

Applications These tapes are designed tomeet the increasing demandfor noise reduction. Basedupon aluminium foil they arespecifically suitable forapplications where a highratio of noise reduction tounit weight is required.Even when exposed torelatively high operatingtemperatures and usualaircraft solvents the longageing adhesive retains itsdamping characteristics.With the added feature of aliner the tape can be die cut.

Damping performance canbe improved by applyingmulti-layers of tape therebyincreasing the overallthickness of the constrainedlayers.

The sound damping tapesperform over a relativelybroad temperature rangebetween -50°C to +30°C.

These tapes arepredominantly used invibration dampingapplications. They are usedto eliminate fatigue cracksdue to vibration of skins,panels etc. Specifically thetapes are used on aircraft,cars, dishwashers andrefrigerators.

Additionally they are usedfor sealing and joining in theconstruction industry and asa moisture vapour barrier.
