Not all sealing failures can be seen with the naked eye. Sometimes, subtle design oversights, improper installation, or even the application's environment if not planned for correctly can quietly undermine your enclosure’s performance.
There's a lot more than just material selection goes into designing a successful enclosure. In this case study, we highlight how Marian and Rogers Corporation teamed up to solve a moisture intrusion issue in a digital intercom system after the original gasket designed by a competitor allowed a leak to damage internal electrical components and, ultimately, caused the devices to fail.
The blog on the Rogers website, What Good Sealing with the Right Partner Looks Like, and the video below walk through how the Marian team recommended materials that effectively sealed the touchscreen modules and also prevented the leaks that previously caused failure.

When it comes to material selection, it's crucial to consider all the forces and elements an application will encounter, even if only occasionally, to truly avoid device failure, and this application story is a perfect example.
Summary of Application & Solution
- Customer: Manufacturer of touchscreen display modules for hospitals & educational buildings
- Original gasket experiencing failure when sprayed with cleaning solutions in regular sanitations
- Marian designed an improved multi-layer gasket solution composed of Rogers Corporation PORON® AquaPro® 4701-41 and 3M™ 9832+
- To improve the gasket and allow for easier handling during assembly, Marian also laminated an antimicrobial film with a pull-tab to the gasket to protect sensitive internal electric components during future cleanings

Marian's material expertise and focus on design for manufacturing (DFM) not only improved the existing gasket by choosing materials that were better suited for the application but also included additional features that made the final solution more practical and presented finished parts in a way that could be easily incorporated into existing assembly processes for the customer.
Whether you’re evaluating a current design or troubleshooting a failure, a reliable gasket can be the difference application between success and failure.
With input from Rogers and Marian, you'll have tools to spec smarter, reduce field failures, and streamline your assembly processes. We'll also bring all the right technical contacts to you instead of you having to do all the leg work. Save yourself some headaches and contact us for help.
