Don’t Just Glue It: Lessons Learned from Zion Williamson’s “Sneaker Disaster”

This entry was posted in Adhesives, General, Uncategorized, Articles on by .

By now, we have all heard about Zion Williamson’s “Sneaker Disaster.” The fact that this incredible athlete sustained injuries, through no fault of his own, shows that “Just Glue It” is not a joke.

We hope that Mr. Williamson will have a speedy recovery and that this product failure will highlight the importance of gluing in manufacturing and the serious nature of product testing.

We, at Glue Machinery Corporation, know you “Don’t Just Glue It.” We have seen similar non-performance issues in product assembly applications from boxes to shoes to cars. As such, we always caution manufacturers against assuming that a strong initial bond is a permanent bond.
It is our recommendation that manufacturers perform extensive tests, using the appropriate gluing equipment and with a range of adhesives to confirm that the bonding characteristics are sufficient for the particular substrates.

Further, we advise that manufacturers develop rigid production guidelines and extensive on-going life testing.

Certainly, not all possibilities can be replicated as shown by the stresses Mr. Williamson’s shoes sustained. He is, after all, one of the biggest, fastest and most talented athletes competing today. Nonetheless, manufacturers of all products have the responsibility to do their own “Glue Diligence.”

Glue Machinery Corporation specializes in industrial gluing equipment and adhesives. We are here to assist with your “Glue Diligence” by:

  • Evaluating and improving your current gluing processes
  • Producing samples with various adhesives specific to your application
  • Producing samples on the best equipment used in manufacturing
  • Recording the process and returning videos and samples as part of your overall Glue Diligence
  • Saving your team time and money if you “Don’t Just Glue It!”

Whether you’re in need of a comprehensive glue machinery solution for a brand new packaging line or are simply looking for an alternative adhesive, you’ll find that there’s no shortage of companies willing to do business with you. Yet how do you determine if a glue machinery supplier has what it takes to go beyond a one-time sale and actually become your long-term partner? Certainly, its pricing will be an important factor in your decision, but there are other things you’ll want to consider. When comparing vendor options, keep in mind the traits listed below.

How To Determine the Open Time and Set Time of EVA-Based Hot Melt Adhesives

This entry was posted in General on by .

Updated March 14, 2019

Open time and set time are two key processing parameters for EVA-based hot melt adhesives (HMA) which will significantly affect the extent of instantaneous bonding and eventual fracture energy. It is not necessary to offer long open time and fast set time for any application. The optimum open time and set time are determined by the application system, the actual bonding process, and bonded substrates.

Synthetic Hot Melt Pressure Sensitive Adhesive

This entry was posted in General, Articles on by .

Synthetic chemicals are used in most pressure sensitive hot melt adhesives. Lower cost synthetic components are being substituted for higher cost synthetic materials by adhesive manufacturers to insure the availability and consistent pricing of hot melt pressure sensitives.

Some manufacturers are claiming incorrectly that they are switching to “Synthetic” materials when they are simply switching from one synthetic component to another. Many of these companies also give the impression that they are switching from “Natural” materials. Most HMPSAs are composed of tackifiers (either synthetic or natural resins), mineral oils, and a small amount of antioxidant.

Adhesive manufacturers will replace Styrene-Isoprene-Styrene block copolymers (SIS) with SIBS or SBS, both isoprene and butadiene used for making SBCs which are all synthetic materials starting from petroleum. None of these are natural materials. In fact, almost all the ingredients, including natural tackifying resins such as rosin and terpene derivatives, used for HMPSAs are all considered to be synthetic materials. Natural materials are obtained directly from paper mills or live trees, cannot be used as is and all require further synthesis to be useful tackifiers.
