Why Hot Melt Adhesives Might be Better for Your Application
Many manufacturers choose water-based adhesives because:
- They offer good resistance to heat, chemical and water influences.
- They can be more economical than alternatives.
But hot melt adhesives can be more effective, depending on your application.
Hot melt adhesives set quickly and maintain strong bonds across a range of temperatures.
Before you place an order for your default water-based adhesive, consider whether the results you get are the results you want. Never stick with an adhesive simply because it’s what you traditionally used.
What Is A Hot Melt Adhesive?
Hot melt adhesives are actually the most widely used across all applications.
They’re solid at room temperature, after application as a molten film or as a series of dots or beads.
Since they don’t use water they have a quick cure and set time.
Ethylene-vinyl acetate (EVA) hot melt adhesives are the most common variety. These work best with paper materials in packaging and assembly. Quick setting times and strong bonding is ideal in high throughput applications like:
- Paper and packaging.
- Automotive assembly.
How does hot melt compare to my water-based adhesive?
Similar to hot melt adhesives, water-based glues are used across industries. The decision to use one or the other usually comes down to bond requirements, equipment type and required production speeds.
Hot melt excels in high volume workplaces, while water-based adhesives take more time to set and are preferred in more niche applications (like those where a more flexible adhesive is required).
So does your current adhesive deliver the quality you want?
Every application is different, and the best adhesive depends on a whole bunch of factors.
Maybe a water-based adhesive worked with your assembly processes years ago, but your packaging changed or the packaging speed on your assembly line increased and the adhesive can’t keep up.
There’s no reason to stay loyal to one adhesive.
A particular adhesive may work in one situation, but not in the next.
When it comes to the right adhesive to choose – it all depends. The best thing to do is to talk it out with a pro. We are happy to offer advice.
Switching to hot melt might have a huge impact on your business, or you might need a custom formulation to get back on track.
