# [Application Story: Antimicrobial Sealing Gasket](https://blog.marianinc.com/blog/antimicrobial-gasket)

Posted by [Katie Sullivan](https://blog.marianinc.com/blog/author/katie-sullivan)

 March 29, 2017 2:05 PM

In this newly released [application story](https://marianinc.com/solution-center/), a global designer and manufacturer of critical intercommunication devices experienced a gasket failure allowing moisture to leak and compromise the internal components of their console. It's remarkable the amount of damage a single drop of water can do. Moisture often contains impurities and minerals that remain even after the water evaporates. Between the moisture and these remaining elements, the contamination can cause short circuits, corrosion, and mechanical problems. A malfunctioning device leads to recalls, replacements, and eventually a poor reputation. The company in this story did NOT want to deal with any of this. 

The intercom console product was intended to be used in medical office settings. Cleanliness and sanitary standards were very important for the high-touch surface of this device. The console was sprayed with liquid cleaners often. The console housing required a reliable sealing gasket to keep moisture out.  

A Marian sales engineer was brought in to review the issue and recommend a solution. The Marian team used their extensive material knowledge and experience to recommend a gasket comprised of three layers:  ![Rogers Water Info chart](https://blog.marianinc.com/hs-fs/hubfs/Rogers-Water-Info-chart-sm-2.png?width=245&name=Rogers-Water-Info-chart-sm-2.png)

1.  The central core of the gasket is **Rogers PORON® AquaPro™ Urethane Foam**. This cellular gasket material offers enhanced water sealing and long-term performance, out-performing other material options initially and over a long service life.

2.  The foam is laminated to an **Autotex antimicrobial textured hard coated polyester film**. When bacteria come into contact with this film the antimicrobial agent disrupts the bacterial cell wall, killing or inhibiting bacterial growth. 

3.  The assembly is laminated to **3M 9832 double coated tape**. This 3M acrylic adhesive provides dependable adhesion to a variety of substrates including the foam of the gasket and molded plastic housing of the intercom unit.

Marian's team quickly provided material samples and rapidly (*the next day!*) created laser-cut prototypes for evaluation and testing. Not only did the new gasket assembly meet the customer's leak tests, but it also gave the customer renewed confidence in the reliability of their system.
