 BonDuit® Evaluation |
Unwilling to accept Polywater's claims at face value, a serious customer intent on performing due diligence undertook a formal evaluation of BonDuit Conduit Adhesive prior to formalizing large-scale usage of the product. Afterward they reported their findings to us. "It is our intention at this point to use your BonDuit product to connect PVC couplings to polyethylene high density pipes. This is to try and replace mechanical couplings that are too bulky. We undertook tests on April 9. The procedure to connect the pipes was followed as per the installation instruction provided in the kit. One of the couplings attached to a 1.25" (32mm) pipe--after three hours of curing--was placed under tension up to 220 lbs. (100 kg), and the polyethylene pipes did not pull out of the coupling. We drilled a hole through the one polyethylene pipe and connected a bolt and chain to it. The other side we connected with a metal sock. "After one hour of pulling at 220 lbs. (100 kg) the pipe itself started to give way at the drilled hole, but there was no movement at the BonDuit Adhesive seal. The pipe was left under tension from 4:00 p.m., April 9th to 9:00 a.m., April 14th--almost five full days. There was no pulling away from the PVC coupling. The pressure did drop down to 165 lbs. (75 kg); however this was due to stretching of the polyethylene pipe at the hole that was drilled. There was no pulling away from the PVC coupling, only slight stretching of the pipe. We were working in temperatures of between 72°F to 77°F (22°C to 25°C). The adhesive starts to harden after five minutes in the nozzle, which means that for our application we would use one nozzle per PVC coupling (both sides). Based on the abovementioned tests I accept that we have followed the procedures correctly and that, as per your installation instructions, the setting time is five minutes." Apparently Polywater's claims about the strength of BonDuit are correct. This example is not as dramatic a testimonial as the famous Smoking Tires Demo from a few years ago, but the independent conclusion is the same: BonDuit bonds PE pipe to PVC couplings like crazy! |
