Bostik, a subsidiary of Arkema, is a global leader in adhesive solutions for the industrial, construction, and consumer markets. Operating in over 40 countries and employing 7,000 people, their product range includes adhesives, tapes, and specialty coatings.

The absence of leaks in production equipment is essential for guaranteeing product quality. Since 2022, Bostik’s production site in Ribécourt has used the Distran Ultra Pro acoustic camera to inspect its compressed air, nitrogen, and vacuum networks.

“The Ultra Pro allows us to detect the presence of leaks — and to validate the absence of leaks.
We save a ton of time by avoiding unnecessary dismantling.

The pre-production check

Adhesives-applications-examples_bostik

The production of polyester adhesives requires specific conditions. During polymerization, a high-vacuum environment with a pressure between 0.5 and 1.0 mbarA is necessary. Insufficient vacuum conditions can cause production delays and even product defects, such as a change in color.

So, before starting a new production run after a prolonged shutdown or maintenance, the team tests the system, checks for leaks, and ensures the vacuum conditions are within the necessary threshold.

After locating and repairing any vacuum leaks, production can begin.

An unexpected issue

In August 2023, the team was preparing to launch a system, but the pressure test failed. The vacuum level was 7 mbarA, indicating air was somehow entering the system.

Their initial approach was to use a single-microphone acoustic detector. This sort of device must be used in a targeted way, so they tested key points in the system where leaks are most likely to occur. This process yielded no results.

Image: Pressure test results – the measured pressure of 7 mbarA far exceeds the acceptable threshold of 1 mbarA.

The last place to look

The Ultra Pro camera was then used across the full system, and the culprit was quickly identified: an unassuming vacuum pump coupling.

This was a surprise, as the inspection team had not considered this part a likely source of the problem and did not think it was worth checking.

“A leak was clearly visible through the Ultra Pro camera at a vacuum pump coupling.
This leakage point would have gone unnoticed without this device.
No one expected it there.”

Work better and faster

Traditional inspection methods typically take 8 to 10 hours. Using the Ultra Pro, Bostik reduced their testing process to just 1 to 2 hours: an 80-87% reduction.

Hundreds of potential leak sources were inspected by the maintenance team—and unanticipated leaks were discovered—in a fraction of the time.

Protect profit margins

Several 10k€

Reduced utilities

Postponing the start of production by even a day would have cost the company several tens of thousands of euros. Therefore, the speed with which leaks are detected and repaired is crucial for minimizing production line downtime and the associated financial losses.

By using the Distran camera, Bostik ensures continuous and efficient production, thereby reducing the company’s loss of earnings and protecting profit margins.

Require less people

Inspections used to involve a minimum of three people. Using the Ultra Pro camera, a single person comprehensively inspects the same area.
Cutting the human resources spent on leak detection boosts the operational efficiency of this process, in Bostik’s case, by 67%.
