Our double face tapes combine our newest adhesive technologies in a format as basic as the original masking tapes to make them the perfect solution for the particular thin bonding problems in the design and manufacture of xEV batteries. Our dual-sided adhesive tapes can offer dependable bindings for battery applications, including pressurised panels, battery module components and cell-to-cell assemblies, with a strong, lasting and chemical resistant temperature. Without time and equipment necessary for curing, our acrylic cords may be used for insulation and space between battery cells, for bonding of certain metals and polymers, identical or different.
High volume production activities with short cycle times and flexibility of processes are needed. A one-piece, cure-by-demand formulation is the Loctite OEM-approved adhesive to hold cylindrical li-ion cells in a transporter. After high speed dispensing, the material is intrinsically open to adaptation through an unexpected production interruption. The material offers a very long duration. The curing process is initiated by ultraviolet (UV) light in less than 5 seconds after all cells are put into an adhesive and sealed in the holder. This is a significant benefit over conventional production, where cure periods range from several minutes to hours and hence require additional parts storage capacity. Covestro’s PC+ABS Bayblend FR3040 EV is the production unit for cell holders. The plastic already fulfils the class V-0 flammability certification of UL94 by Underwriters Laboratories with a thickness of only one mm, while showing good UV radiation permeability across a wavelength of over 380 nanometres. The material makes it possible, for automated mass assembly, to build dimensionalally stable pieces. This combined material provides a novel method to large-scale cylindrical LI-ion battery manufacturing, together with the rapidly cured capacity of loctite adhesives. For , please visit our site.
Even on large surfaces such as modules, our adhesive transfer tapes provide a precise and uniform adhesive application. These double-sided tapes have a wide range of movable carriers and on each side various adhesives and liners. They perfectly meet your criteria for assembly and application and assist to facilitate staged assembly. Extended tab lines available allow for automatic use.

A closed cell-acrylic foam core for the filling of the narrow bond space between between bacteria is available in our double-faced 3MTM Acrylic Foam Tapes. Acrylic foam core technology â THIN â utilised for decades to cope with outside automobile trimming stresses â is compressible and offset cell expansion, therefore helping to maintain battery performance.
Wide range of materials
Adhesion to a wide range of metals, polymers – including polypropylen and polyéthylene – and composites throughout the whole life of the vehicle were developed for the adhesives used for all 3M doublesided tapes.
Adhesives are available for resistance to moisture and humidity on textured surfaces in heavier coat weights. Adhesive tapes can assist remove stress-related failures of the substratum on flat modules and plates, whether used in conjunction with or in place with mechanical fasteners. Sustainable film carriers withstand high temperatures and chemical components.
Preserves battery performance
A closed cell acrylic core for narrow spacing between the battery cells is available in our double-sided 3MTM Acrylic Plus Tapes. This substance enables compression, stress compensation and helps to retain battery performance during cell growth.
The design engineer has key advantages
xEV battery designer 3M double-sided tapes provide innovative methods to tackle the small bonding problems. For either side of the band, engineered adhesives may be chosen to permit bindings to different substrates of metal and plastic. Glue transmission tapes enable the constant use of adhesive over wide surfaces without a sticker. Double-sided tapes can also provide simultaneous electrical insulation and can be utilised without the requirement to specify extra materials as separators between the cells. Our two-sided tapes may be readily cut into nearly every form for xEV batteries.
