The Bonding Poly Process TM (BPP) (Patent Pending)
For gluing poly-plastics and other polymers, the Bonding Poly ProcessTM gives you the technology and the steps required to make a permanent bond or repair, quickly and easily. Bonding polypropylene, polyethylene, polyurethane, ABS, Teflon®, Delrin®, Lexan®, silicone rubber and any other polymer was considered impossible. However with the Bonding Poly ProcessTM, you can easily bond a polymer to itself or to any other substrate. In addition, repairs of broken poly’s are easily accomplished.
Sound to good to be true? We do understand your skepticism. That’s why we offer a money back guarantee. If you purchase a poly repair kit, and you can’t make the repair, we will issue a full refund of the purchase price. An overview of the Bonding Poly ProcessTM is given below.
- Make sure the surface is clean.
- Begin by saturating both edges or surfaces(1) of the poly item to be repaired/bonded with the Poly Prep.
- Let the Poly Prep dry.
- Spray one edge/surface with a solvent based Activator/Accelerator (A/A). (2)
- Let the A/A dry.
- Take a blow dryer or a heat gun and WARM both edges/surfaces for thirty seconds. Don’t overheat. Poly surface(s) should be warm, not hot. Typical temperature range is 115 degrees Fahrenheit, plus or minus 5 degrees.(3)
- Apply an SI structural adhesive (Usually SI Blue) to the opposite edge/surface from where the AA was sprayed.
- Bring the two edges together and firmly press for fifteen to twenty seconds.
- Take the hair dryer or heat gun and warm the seam for thirty seconds.
(1) Only co-polymers, polyolefins and polymers need primed. If one surface is not a polymer, poly-plastic, or polymer, i.e.. is not an oil based plastic, it does not need primed.
(2) Alternatively, you can apply the SI adhesive on one surface, press the two edges together and then spray the seam with the A/A. Then heat the seam for 20 – 30 seconds.
(3) If you don’t have heat available, you will still get an excellent bond by just using the Poly Prep. A/A and an SI adhesive. If you don’t have either heat or the A/A, the Poly Prep and SI adhesive will usually produce a glue join but not a bond.
Three things of note.
First, even though bonded or repaired poly pieces can be put into use almost immediately, it can take poly’s up to seven days to fully cure.
Secondly, poly pieces are often long and thin even though there is often a lot of stress involved. An example would be the tabs of a head lamp assembly. Because of the stress it is often wise to add strength to the repair. To add strength apply a patch to the bond/repair. Recommended patches include fiberglass patches or sports tape. The procedure for strengthening a bond or repair is given below.
- Cut patch to fit.
- Prime the area where the patch is to be applied with the Poly Prep.
- Warm the area with a heat gun or hair dryer. You want the area to be warm to the touch.
- Apply a layer of an SI adhesive to the area.
- Apply the patch.
- Apply two coats of SI adhesive on top of the patch, smoothing each layer.
- Spray a small amount of Activator/Accelerator on the patch.
You have substantially increased the strength of your bond or repair.
Finally, with these techniques you can bond poly’s to themselves, to any other poly or to almost any other substrate. If the other substrate is not a poly, it does not need primed or heated.
