Why these bonding tapes are used:
Convenient method of bonding
Clean and simple to use
Instant adhesion
No drying time
Move on to the next part of the process
User friendly
No drilling or damage to substrates
No contamination of other components or work surfaces
Converted into shapes to match receiving components
Consistent adhesion performance
Consistent layer/thickness of adhesive
No hazardous fumes
Encourages Good design - no holes or mechanical fixings
Plus,
Can be used on plasticised surfaces
Insulation between ali and steel to stop electrolytic corrosion
Third hand to bond while another fixing method is used
Add second colour to reverse printed graphics
Pre-assembly before on site construction
Useful Reminder:
The smoother the surface - the better the bond
| Common Problems |
SOLUTION |
| 1. Contaminated surfaces |
REMOVE ALL CONTAMINANTS WITH AN IPA WIPE * |
| 2. Distortion or peel Forces |
AVOID, OR CORRECT THE DESIGN |
| 3. Low temperatures |
AVOID TEMPS BELOW 10oc OR ALLOW TIME FOR THE BOND TO FULLY ‘WET OUT’ |
| 4. Differential thermal movement |
USE FOAM TAPE OR TECHNIFLEX TO ALLOW FOR ANY MOVEMENT BETWEEN SUBSTRATES |
| 5. Plasticised substrates |
USE HIGH PERFORMANCE ACRYLIC ADHESIVES |
| 6. Low energy surfaces (PU PE PP Nylon) |
USE THE WETTER HIGH TACK DS TAPES |
| 7. Shear movement factors |
USE THE DRYER HIGH SHEAR RESISTANT DS TAPES |
| 8. Rough or uneven surfaces |
USE A FOAM TO TAKE UP ANY IRREGULARITIES |
| 9. Not enough pressure applied |
APPLY OVERALL HAND PRESSURE TO SECURE THE TAPE, OR USE A HAND ROLLER OR LAMINATOR |
* Sachets of Isopropanol (IPA) wipes are available from Technibond

P apply Pressure to ensure complete surface contact
T allow Time to allow the adhesive fully ‘wet out’
The Thumb Test
Most users tend to judge the tape’s adhesion ability by the ‘thumb test’ - the wetter the feel, the sticker it appears, so surely the better it must bond ?
In fact, the opposite is true. What they are feeling is simply how ‘wet’ the adhesive is.
Think of treacle – very sticky, but too liquid to hold anything in place for more than a few seconds. In contrast, the Technibond PURE ACRYLIC adhesives will hold heavy mirrors and metal components in place indefinitely. Yet, they would be rejected by the standard ‘thumb test’!
Actual performance results prove, when applied correctly, the outstanding ability of these dryer ‘cross-linked’ adhesive products, especially for extended periods in exposed environmental conditions.
Generally all our higher performance products use a ‘cross-linked’ adhesive system to provide a stable, long term secure bond
Adhesion Factors
 |
Tensile Adhesion |
No external forces, other than weight and gravity
Recommended
‘high tack’ products:
HTA, HSHT
|
 |
Shear Adhesion |
Good cohesive properties to resist the slide effect which may happen over time. Temperature may also soften some lower grade adhesives, allowing the slide movement
Recommended
‘high shear’ resistant products :
HSA*, HSHT
* ten year guarantee |
 |
Peel Adhesion |
Good adhesion, plus strong carrier to resist the effect of a peel forces.
Recommended
‘high peel’ resistant products:
HPA, Techniflex |
