Inline Corona treatment surface modification for LSE substrates, liquid priming, and surface embossing can be used to improve adhesion during lamination or die-cutting processes.
Surface Treatment Options
INLINE CORONA TREATMENT
High energy Corona discharge effectively severs molecular bonds on the surface of the material and attach to free radicals within the Corona discharge. This results in enhanced surface energy and increased adhesion of various materials.
Liquid priming is the controlled application of a specially formulated liquid primer or coating onto the substrate's surface before further processing. The primer enhances the substrates adhesion properties by creating a more suitable surface for bonding.
Surface embossing involves creating patterns or microstructures on the substrate's surface through thermo mechanical processes. These patterns create micro grooves within the adhesive surface eliminating trapped air during application.
Inline Corona Treatment for LSE Substrate Surface Modification
Surface treatments modify the surface of low surface energy (LSE) substrates during the die-cutting process to allow application of pressure-sensitive adhesive (PSA) to materials which have an inherent LSE that were previously incompatible with PSA.
Inline Corona Treatment increases the surface energy dyne level of LSE materials such as foams, composites, acrylics, films and PP by up to 3 times.
This highly effective treatment allows the lamination of conventional PSA’s onto LSE substrates that would otherwise not be available, without any reduction in manufacturing speeds, eliminating the need for high cost chemical surface preparation and specialist adhesives.
Using this surface modification during the die-cutting process and prior to bonding, coating, laminating or sealing broadens the range of adhesive tapes and substrates that are compatible with LSE materials previously unsuitable for the same application.
Particularly important during the manufacture of medical components, devices and equipment, enabling Material Scientists to utilise cleaner materials and helping to replace substrates such as vinyl and latex. With greater design flexibility, we are able to support our clients in the development of tomorrow's technology.
Heat application For Thermally Activated Adhesives
Thermally activated adhesives require heat to initiate bonding. Enhancing the substrate's surface properties through corona treatment or priming provides several advantages during lamination or die-cutting processes.
Incorporating these surface modification techniques into the production process is particularly valuable when working with challenging substrates or when achieving strong, reliable bonds is critical. By addressing the inherent limitations of LSE substrates, we can enhance the performance and durability of products that involve lamination, die-cutting, or other adhesive bonding processes.
We have the flexibility to convert all our industrial double-sided adhesive tapes into customised solutions for customer specific bonding and mounting applications, available in various formats, including die-cut components, rolls, sheets, and adhesive pads.
Tecman’s range of high performance surface protection film and masking tapes are used to protect surfaces during manufacturing processes in demanding industries such as automotive, electronics, and wind blade protection in the renewable energy sector.
Our high-performance foam and acoustic materials are converted into custom components for a wide range of industries and applications, including sealing and cushioning, through to NVH management in electric vehicle powertrains.
