Structural Adhesive Tapes

Alamotape® compounds a proprietary line of thermosetting adhesives that provide extremely high bond strength for a variety of applications. These adhesives, also called heat activated or B-stage adhesives, are cured using heat and/or pressure and can be bonded to a wide variety of substrates from low to high surface energy. These unique adhesives are designed for extreme high temperature applications and are available with flame retardant capabilities. All Alamotape products are Restriction of Hazardous Substances (RoHS) and Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) compliant. Alamotape offers two types of Structural Adhesive Tapes:

Tack-Free Thermosetting Adhesive Tapes are cured with high heat and pressure, resulting in extensive cross-linking between polymer chains to produce an infusible and insoluble polymer network. The curing process creates a chemical bond that, unlike a thermoplastic, prevents the material from reflowing. These adhesives are tack-free at room temperature; no release liner is needed.

Tacky Thermosetting Adhesive Tapes are tacky at room temperature, providing initial bond similar to a pressure sensitive adhesive tape. Like the tack-free products mentioned above, applying heat and pressure results in full cure and high bond strength. These products are tacky at room temperature and require a release liner.

(Tacky) Alamotape 5105 Tacky Thermoset

Alamotape 5105 Tacky Thermoset performs like an acrylic PSA at room temperature, then cures like an epoxy when heat and pressure are applied. It can withstand up to about 400°F for prolonged periods of time once fully cured. 5105 Tacky Thermoset performs best on medium to high surface energy substrates, particularly metal to metal bonding. It comes standard as a transfer tape but can be supplied with most available substrates to add functionality.

(Tacky) Alamotape 5202 Tacky Thermoset

Alamotape 5202 Tacky Thermoset has excellent initial tack and peel strength at room temperature – outperforming most PSA tapes. With added heat and pressure, the adhesive then cures to even higher bond strength. This adhesive tape is designed for low surface energy substrates including most plastics. 5202 Tacky Thermoset is ideally suited for thermoforming applications where dissimilar substrates can be fused together during the forming process.

(TACK-FREE) AFR Coated Products

Alamotape’s Acrylic Flame Retardant (AFR) adhesives can be coated onto many flexible substrates including Kapton, Nomex, and PolyEthylene Terephthalate (PET). Our AFR adhesives are supplied in B-stage form and can be fully cured with heat and pressure. Flammability ratings range from UL V-0 to V-1 when subjected to a vertical burn test. Our products have varying degrees of self-extinguishing properties. Please contact us for more information about the flammability ratings of our products.

Flex, Flat, or Ribbon Cable: Our products insulate conducting wires running parallel on a flat plane commonly used for internal peripherals in computers, hard drives, and compact disc drives. These cables are prevalent in automotive applications in addition to televisions, monitors, and cell phones.
