Epoxy Mixing Nozzles for Two-Part Epoxies
A two part epoxy requires proper mixing to work effectively. If you use too little or too much catalyst, the epoxy will not set correctly. That is where epoxy mixing nozzles come into play and are highly important parts of proper epoxy application. When you use the correct type of mixing nozzle with the kind of epoxy to be used, application is much faster and you get the epoxy exactly where you need it for the best possible bonding action.
Epoxy mixing nozzles mostly boil down to two basic types You have standard static mixing nozzles that work in a variety of ways. You also can choose a Quadro static mixer, which is a newer development in the two part epoxy application process. Quadro mixers also are called turbo mixers and enable better mixing in shorter dispensing nozzles.
Each type works best under varying circumstances and can use a variety of epoxy products, like those from Infinity Bond. Here is a closer look at each to help you better choose the right one for your epoxy adhesive applications.
Standard Static Mixer
The standard static mixer often is a disposable nozzle that attaches to a meter-mix-and-dispense (MMD) tool that somewhat automates the process. The MMD tool specifically measures the epoxy and catalyst compounds to provide the ideal mixture and best results. The mixing nozzle might be an in-line variety or a more commonly used disposable bayonet system.
A bayonet mixer nozzle typically has a handheld unit that works like a glue gun with the catalyst attached in a separate container and in a fashion similar to affixing a bayonet to a military rifle. The disposable units are very affordable and among the most popular.
A standard static mixer also could be a handheld dispenser that you operate manually and does not have a metering component. The two part epoxy already is pre-measured and combined with the mixing nozzle to deliver fast results. The handheld dispenser typically is easy to use on smaller tasks while the MMD tool is ideal for more industrial applications.
Quadro Static Mixer
The Quadro static mixer is more commonly used in industrial applications. They function similarly to an MMD static system and enable machinery function in a more automated fashion. That is especially important if the task involves industrial applications that require epoxy in specific amounts and locations quickly, accurately and affordably.
Quadro mixers produce less waste than standard static mixers, but they do typically require some level of automation to work. As long as you have the correct dispensing equipment, you can use a variety of two part epoxy adhesives to bond a wide range of materials using the same Quadro static mixing nozzles for epoxy.
Factors Affecting Epoxy Mixing Nozzle Choice
While Quadro and standard static mixers generally differ in how they are applied, they both accomplish the same thing. The mixing nozzles ensure the two part epoxy adhesive is used in exactly the correct manner and amounts.
The type of mixing nozzle needed will vary based on the shot size each time epoxy adhesive is needed to complete a task. The larger the shot size and the faster it is dispensed, the more volatile the actual mix becomes.
Smaller sizes of shot generally need more mixing and a smaller nozzle to get it done, while the larger shot size requires a larger mixer. The larger the mixing nozzle, the less efficient the mix, and that could be a problem. Clearly, exact selection of the correct type of epoxy mixing nozzle is critical to ensure the best results for your bonding needs.
