Bond Failures and Products Opening
When a Bond Doesn’t Hold, the Adhesive Isn’t Always the Problem
Products opening, separating, lifting, or delaminating can create scrap, rework, downtime, customer complaints, and damaged products. But a failed bond does not automatically mean you need a stronger adhesive.
Reliable bonding depends on the entire application: the substrates, adhesive, application method, temperature, compression, open time, production speed, storage conditions, and what happens to the finished product after it leaves your facility.
At HAR, we start with the failure and work backward.
Finding the Real Cause
A bond that looks good when it leaves the production line may fail hours or days later. A product that has run successfully for years may suddenly begin opening after a seemingly minor change.
We help evaluate questions such as:
Has a substrate, coating, recycled content, or supplier changed?
Is the adhesive being applied at the correct temperature and amount?
Is there enough compression—and at the right time?
Has production speed increased?
Are application patterns consistent?
Are temperature or storage conditions affecting the finished bond?
Is contamination interfering with adhesion?
Does the current adhesive technology still fit the application?
Sometimes the answer is a different adhesive. Sometimes it is an equipment or process adjustment. Often, the best solution comes from understanding how all of those factors work together.
Start With What Is Opening
Tell us what is failing, when the failure occurs, the materials being bonded, and anything that has recently changed.
Photos, failed samples, adhesive information, equipment details, and production conditions can help us identify where to start.
You don’t need to diagnose the failure before calling HAR. That’s what the conversation is for.
Why Manufacturers Contact HAR About Bond Failures
Cartons, cases, or packages are popping open.
Laminated materials are separating.
Bonds fail during shipping, storage, or temperature changes.
A previously reliable application has become inconsistent.
New coatings, recycled content, or substrates are harder to bond.
Increasing adhesive hasn’t solved the problem.
The customer needs help determining whether the problem is the adhesive, equipment, material, or process.
