Potting Electronics With Hot Glue - Is It Possible?
Hot glue or hot melt adhesives are thermoplastic materials used in quickly assembling and bonding items. The thermoplastic qualities make the adhesives moldable or plastic under heat but solid in normal conditions. Hot glue can bond even dissimilar materials together impressively when properly handled.
Hot glue is used in a wide range of industries and products and is also used to seal fiberboard and paperboard or assemble plastic toys. The glue has become usable in fabricating delicate electronic components so that you can use hot glue to pot electronics.
The advantages of using hot glue in potting
Hot glue's first and obvious advantage is that it is easy to melt and mold as desired. The glue, therefore, makes an amazing choice in gap-filling. The shelf life of this adhesive type is stable and reliable, and because it has no toxic chemicals, it is an environmentally friendly material.
Hot melt adhesives do not weaken with humidity changes. If a tight bonding is what you are looking for, then the glue will work effectively. When you use it for potting, you can be sure no moisture will build up and harm your electronics.
However, it is also good to note that because the glue needs heat to melt and mold as needed, it is not a very good option for electronics used under extreme heat because it will melt easily. Hot glue should not be an option if you are potting electronics that produce high heat levels during use. But when compared with other adhesives that can be used for potting electronics, hot glue has:
• Minimal waste
• Long shelf life
• Reduced environmental disposal precautions
• Rapid curing and drying
• Tamper resistance seals
• No shrinkage during curing
• Higher color additive acceptance
• Low-cost and simple applicators
Whereas epoxy is a popular material in potting, the truth is hot glue can exceed its binding strength with the right formulation. Hot glue is versatile as an adhesive but unsuitable in high melting temperatures and some solvents. You will also need to be careful when potting because the hot glue can scorch the skin; the temperatures can be as high as boiling water. But with the right applicator, like a hot melt gun, you should have an easy time putting the glue only where necessary on the electronic.
When using hot glue for potting electronics, it is important to consider how suitable the glue will be on the components. Some electrical components can be too sensitive to handle the heat, and this could mean damaging them. Ensure that the electronic assembly or components can withstand the temperatures without getting damaged.
Potting electronics with hot glue also require proper handling. You can easily get guidelines from your supplier to ensure you get it right. The wrong application will not only render the protective layer useless but can also damage your electronics permanently. If need be, seek assistance or insight from professionals. That way, you will know whether it is appropriate to use hot glue for your application and exactly how to do it.
