Road- & commercial signs
The two major areas for AFTC SilverTape in this market
are without a doubt road signs and commercial signs.
Road signs are in most cases made of an aluminium
sheet or sandwich panel bonded to a steel frame.
In the past, rivets were used to attach the panels
to the frames. Because of the two different metals
being used and the rivets being pressed through
the materials, bi-metal corrosion was very common.
Using AFTC SilverTape offers an excellent solution for
this by forming a barrier between the frame and the
sheet. Besides this, other advantages are an increase
in productivity and obvious aesthetic improvements
compared to the many visible rivets in the past.
Commercial
Commercial signs on the other hand have more
aesthetic value and are in many cases made of
translucent materials such as polycarbonate, PMMA
or polyester. The combination of bonding to these
materials and the demands of the customers
concerning the (in)visibility of the tape has been
a challenge. AFTC’s transparent SilverTapes have
proven to be an excellent solution. These optically
clear tapes are relatively soft and therefore extremely
conformable to ensure a good adhesion to the above
mentioned polymers.
