Put An End To Adhesive Mixing Errors
January 22, 2015
January 22, 2015 - Anyone who has worked with two-component adhesives in a production environment knows that it can be tricky to get the mix ratio right day in and day out.
In fact, we’ve found that mixing errors are the leading cause of manufacturing inefficiencies and scrap in both bonding and potting operations. Even worse, an incorrect mix ratio can sometimes result in an adhesive joint or encapsulation that looks good but actually suffers from reduced mechanical and physical properties.
One of the most effective ways to avoid the mix-ratio problem is to use a dual-barrel dispensing gun that works with cartridges containing the required adhesive components.
Our TriggerBond® system is a leading example of this dispensing approach. It provides consistent, volumetrically-precise control of the adhesive components. It also makes the mixing and application of two-component adhesives less messy on the shop floor. And unlike automated dispensing systems, TriggerBond requires no investment in capital equipment.
In the right application, the advantages of TriggerBond dispensing can be compelling. Manufacturing operations become more efficient—in part because TriggerBond dispensing is fast and in part because it prevents rework and scrap.
However, not every application is well-suited to TriggerBond products. With that in mind, here’s an overview of the application requirements that are a good fit:
- The right type of adhesive. TriggerBond can accommodate a broad range of adhesive products, but some formulations simply don’t lend themselves to this kind of dispensing. Highly-filled products, such as thermally conductive potting compounds, don’t tend to work well in dual-barrel cartridge dispensers. Other adhesives have extreme viscosities that may rule out their use in a TriggerBond dispenser. And finally, TriggerBond works only with adhesive products that have fixed mix ratios. Even with these limitations, we have over 50 TriggerBond-friendly formulations available. ?
- The right production volume. For high production volumes, other automated dispensing systems tend to become more efficient than TriggerBond. For example, TriggerBond may not be the best option for a continuous sealing application that requires a bead of material dispensed over a long distance—such as automotive window sealing applications. Even if you do have a high-volume application, keep in mind that TriggerBond can help you scale up to full production volumes. Prototype and first article production may start out in TriggerBond even if ongoing production uses some sort of automated dispensing. Consistency between the TriggerBond and bulk formulations makes it possible to scale up without changing adhesives. ?
- The right workflow. TriggerBond is particularly useful in assembly lines that require intermittent adhesive application. Many job shops fall into this category. So do many lean, just-in-time and continuous-flow assembly lines. In these cases, buying adhesives in bulk may not make sense, even if production volumes are higher than our rule of thumb.
