Fabric delamination integration

For industrial applications, surface preparation before bonding is a key step to ensure product performance. This process is frequently time- consuming due to the manual nature of the work, which is difficult to duplicate and expensive. GEFICCA identified this issue and has developed rubber products featuring ready-to-use surface preparation technology.

GEFICCA has designed a process directly integrating a delamination fabric into the molding of its parts. This fabric is then removed just before the bonding step, taking with it a thin layer of rubber. This technology offers several major advantages: 

• No more mechanical preparation needed: The removed fabric leaves a specific texture, increasing the bonding surface and further improving adhesion.
• An always-ready surface: The user removes the delamination fabric just before bonding, thus ensuring a clean surface until bonding. This considerably reduces the risk of environmental contamination.
• Improved bonding: The removal of the fabric takes with it the thin molding skin, thus exposing a chemically more active surface that contributes to better bonding. This ensures quality adhesion.
• Cost reduction and reduced arduousness. The user then benefits from a turnkey solution that will simplify their bonding process and manufacturing costs.
• Reduced arduousness and improved reproducibility: This new process offers the possibility of no longer having to go through manual preparation phases, which are very often arduous for operators and poorly reproducible. This ensures consistent and repeatable bonding quality.
• Laboratory tests, on tensile and peel test specimens, have confirmed the effectiveness of the delamination fabric. Advanced tests simulating several types of pollution have demonstrated the fabric's ability to render a clean surface compatible with quality bonding. 

With this new process, GEFICCA offers a ready-to-use rubber solution that allows our product to be bonded directly, thus contributing to our customers' performance while reducing their manufacturing costs.
