Adhesion Solution

The conclusive adhesive!

The bonding together of the components of a final HMI or a smart surface is a critical step in the production and manufacturing process, and the best end results occur when quality meets innovation. e2ip offers expertise in various types of industrial adhesives for HMI assemblies, such as pressure-sensitive adhesives (PSA) and electrically conductive adhesives, and this expertise has led to our own proprietary adhesive solution: HeatSeal™.

HeatSeal Adhesive Solution

This technique sees multiple e2ip HeatSeal™ layers added as adhesives within the circuit layer stack, during the construction process of membrane switches, HMI, or smart surface applications. It is a bonding system that is tested to the extreme, certified, and guaranteed to protect circuitry from specific harsh environments.

e2ip HeatSeal™ is a proprietary fabrication process for superior lamination that is used to enhance the build and performance of all types of user interfaces, with a variety of HeatSeal™ types available. The specifics of the fabrication process are innovative and environmentally friendly by design, adding to the overall appeal of HeatSeal™. Manufactured with rigorous testing, this method results in a completely sealed switch, effectively helping to eliminate one of the major causes of mechanical failure – inadequate sealing.

HeatSeal™ offers custom products containing a smarter and safer bonding system solution that remains cost-effective and offers a wide range of options for build and function support.

Another bonding system offered within our adhesive product category is the Pressure Sensitive Adhesive (PSA). 

PSA is a pressure-enabled bonding substrate that needs no heat, water, or another solvent to activate the adhesive properties. In the case of HMI, PSA is used to fuse the layers of an HMI assembly. Electrically conductive adhesives are solder-free and support assemblies by not only bonding components together but also allowing for the passing of electrical currents.
