Problem: Customer contacted ourselves with a problem, their ceramic tiles were falling off the display boards in the showroom.
Application: Customer is bonding a mixture of brick, marble, granite and ceramic tiles to their display boards.
Fail: The competitors hot melt adhesive was failing, tiles were simply coming unstuck and falling off. The adhesive was hard grade with no flexibility and with the cold temperatures we are experiencing the adhesive was too brittle and with handling of the boards and the stress was causing the bond to fail. You don’t want tiles falling off in your showroom with a potential risk of striking a customer!
Solution: Tecbond 261 is a uniquely flexible hot melt that is quite different to all other hot melt sticks, Once set it remains extremely flexible. This enables it to withstand both shock loading, and the stresses caused by thermal expansion. The thermal expansion is an important factor with ceramic tile displays, the ceramic tiles do not expand or contract much with temperature changes, however the wooden boards they are attached to do.
This means that very high shear forces can occur along the adhesive line as the temperature changes, The larger the tile, the larger the distance between the blobs of adhesive and the higher the stress due to the different expansion rates. The problems tile display manufacturers face is that many ordinary hot melts initially look as strong as the Tecbond 261, but as the temperatures change with the change the less flexible adhesives are put under increasing stress until tiles start falling from boards, often 6 months later.
The benefits of using Tecbond 261 outweigh the small savings made by switching to the lower cost standard adhesive.
