Preventative Maintenance: A Guide To Cleaning Your Hot Melt Adhesive System

Why It's Important To Clean Your Hot Melt Adhesive Equipment 

The invention of hot melt adhesive equipment has made it easier than ever for manufacturers to produce and package their goods across a wide variety of industries. From sealing cartons to binding books, hot melt adhesive machinery can offer a more efficient and less wasteful process to get products into consumers' hands. But over time, these machines can become clogged with residue from the adhesives they dispense — leading to poor performance and reduced efficiency. 

As such, it's essential to take preventative measures by regularly maintaining and cleaning hot melt equipment in order to keep it in excellent condition. In this blog, we'll discuss the importance of cleaning your hot melt equipment, which cleaning solutions our experts recommend, and how best to go about cleaning your machinery.

How Hot Melt Buildup Can Affect Your Business Operations

Removing residual hot melt adhesive from your equipment is crucial for several reasons. Not only does it ensure that the equipment operates at its optimal level, but it can also extend the lifespan of your hot melt adhesive system. Machinery like nozzles, hoses, tanks, and conveyor belts can get clogged by residual adhesive buildup. 

This buildup, in turn, can cause: 

    • Uneven adhesive application
    • Product defects
    • Higher reject rates
    • Increased downtime
    • Premature wear and tear
    • Costly repairs or replacements

More importantly, though, it is essential for the health and safety of your workers, as residue buildup can gradually release toxic fumes that are harmful to your employees' health.

Experts Recommend Infinity Bond Hot Melt Adhesive Cleaners 

While there are many different hot melt system cleaners available, like Henkel Technomelt Melt-o-Clean, our experts recommend Infinity Bond EnviroClean as a surface cleaner. Because despite being a widely recognized cleaning solution in the industry, Melt-o-Clean has been discontinued for some time now

In selecting a replacement product, our experts choose Infinity Bond EnviroClean for its similar properties to Melt-o-Clean as a cold cleaning agent that can clean machine surfaces to remove not only residual adhesive but also heavy grease and grime. EnviroClean also won over our experts for its value and cost-savings compared to other hot melt adhesive cleaners.

For those looking for more than just a surface cleaner, our experts will point you to Infinity Bond Enviroflush. Enviroflush is a cleaning solution used for purging hot melt adhesive systems. Like EnviroClean, Enviroflush is specially formulated to remove hot melt adhesive residue from machinery and equipment without causing any damage. It is biodegradable, non-toxic, and requires no mixing to use.
