German researchers are working on a quick-setting construction tape which can bond lumber members together. They’ve developed an adhesive tape, which sets in under a minute to reliably and durably bond together individual components.
The construction tape doesn’t dry out, so it can be applied to one member, and does not have to be immediately sealed to other pieces.
The entire process is possible because the adhesive material actually envelops a metal strip which serves as a heating system. When the construction tape is stuck onto a piece of wood, the part contacting the wood warms, allowing it to seep into the wood grains. It then cools, creating a bond. Stick another piece of wood on the other side of the tape, the same process is repeated, and the two pieces are sealed together.
While the process currently takes about a minute, the aim is to speed it up.
Researchers feel they have found the perfect adhesive, but they still are working on finding the ideal metal for the heating strip. Besides brass, scientists are also testing stainless steel and aluminum.
“As the adhesive tape is designed to be used primarily for load-bearing bonding in buildings, it has to possess structural strength and durable adhesive qualities,” says Dr. Andreas Zillessen of WKI (Wilhelm-Klauditz-Institut).
The time frame for real life testing of the product is about six months away.
Imagine – instead of whacking my thumb with a framing hammer, I will now be able to permanently tape my hands together!
