Video Description: How to Use the Resin Dropper
In this video, we discuss how to use the dropper that comes in your MagniBond resin. A common myth among technicians using Delta Kits windshield repair equipment is that the resin eats the dropper. That is not the case. Technicians actually over tighten the cap, which deteriorates the bulb and causes it to leak.
Delta Kits gives an example of a technician properly tightening the cap, where you notice in the video that it’s just snug. With merely a snug fit, the resin will not leak. Delta Kits gives another example of a technician over tightening the cap, where you notice the separation between the bulb and the cap. This is what causes the cap to leak.
The dropper bulbs are not made of rubber, they are made of a special Thermoplastic Elastomer (TPE) that is extremely resistant to windshield repair resins. Most rubber compounds will soften and deteriorate in windshield repair resin. But the Thermoplastic Elastomer that Delta Kits uses will not, and we have proven that fact over and over again by soaking our resin bulbs in resin for months at a time. When they are removed from the resin they look, feel, and perform just as they did prior to being soaked. You notice an example of this in the video.
Other than over tightening, the only problem we have seen with the dropper in the 25 plus years we have been using them, is when a technician stands the bottle up in a tool box that does not offer enough clearance when the lid is shut. In that instance, the rubber may crack by repeatedly being folded over causing it to leak. Even in a Delta Kits tool box, this can happen if the removable top tray is put in backwards. The video provides examples of resin being properly and improperly stored in the top tray.
If a technician still struggles with the resin dropper after following the above procedures, technicians can try using MagniBond in the plastic squeeze bottles (144-8), which eliminates the dropper completely. MagniBond is also available in pre-measured, one-shot syringes (144-8SS). A third option is to use Delta Kits MagniBond in a glass or plastic bottle, with a UV resistant syringe.
All gloves do not provide the same level of protection. For example, latex and vinyl gloves which are typically skin tone in color, offer little to no protection against many of the chemicals used in windshield repair. They are also easily permeated and degrade quickly. In contrast, nitrile gloves, which are typically blue or black in color, provide a better barier because they offer low permeation and higher resistance to chemical degradation. They are also more durable.
