AFTC 5359
AFTC 5359 is a 0.118″ thick, double-sided closed cell acrylic foam tape in the SilverTape family, designed for bonding a wide variety of materials with high and medium surface energy. It delivers 90° peel adhesion of 23 lb/in, dynamic shear strength of 58 lb/in², and tensile strength of 77 lb/in², and operates across a temperature range of -40°F to 248°F long-term and 374°F short-term. The tape maintains high impact resistance at sub-zero temperatures and is formulated to absorb differential thermal expansion between dissimilar bonded materials.

- Structural bonding of glass and glass/epoxy panels to metal frames where maximum gap accommodation, highest peel retention, and sub-zero impact resistance are required
- Bonding of coated and anodized aluminum components with large bondline clearances requiring absorption of differential thermal expansion
- Attachment of stainless steel and galvanized steel parts in assemblies with significant surface variation where conformability and sustained static shear at elevated temperatures are critical
- Cold-environment structural bonding applications requiring maintained impact resistance below 0°C
- Medium surface energy substrate bonding in combination with H-O Products Primer 33 or Primer 101
Common industries: Industrial assembly, architectural glazing, automotive manufacturing, transportation, metal fabrication.
AFTC 5359 is the thickest grade in this SilverTape set at 0.118″, designed to bond a wide variety of materials with high and medium surface energy — including glass, glass/epoxy, stainless steel, galvanized steel, anodized steel, and coated aluminum. The TDS cites toughness and the tape’s ability to maintain high impact resistance at temperatures below 0°C as key characteristics.
The acrylic adhesive foam core is closed cell and carries a permanent adhesive system on both faces, protected by a red PE liner. The substantial thickness provides maximum gap-filling and conformability within the series, and AFTC 5359 delivers the highest 90° peel adhesion in this SilverTape set at 23 lb/in.
The tape exhibits excellent UV resistance and excellent solvent resistance per the TDS. Static shear strength is 1,500 grams per 1/2 square inch held for 10,000 minutes (7 days) at 72°F, 1,000 grams at 150°F, 750 grams at 200°F, and 750 grams at 250°F and 350°F. Surface preparation is critical: substrates should be cleaned with IPA for light to moderate contamination, or MEK, Heptane, or Acetone for heavy contamination followed by an IPA wipe.
Raw aluminum must be abraded prior to bonding. A minimum bond-line pressure of 14.5 psi must be applied. Full end-strength is reached within 72 hours; use of H-O Products Primer 33 or Primer 101 reduces this to approximately 20 minutes. Minimum recommended application temperature is 59°F.
What differentiates AFTC 5359 from thinner SilverTape grades such as AFTC 5313 or AFTC 5312?
AFTC 5359 is 0.118" thick — approximately 50% thicker than the 0.078–0.079" grades. It delivers the highest 90° peel adhesion in this SilverTape set at 23 lb/in, and its static shear strength at 150°F is 1,000 grams — higher than the 500 grams listed for the thinner grades. The TDS also explicitly calls out high impact resistance at sub-zero temperatures, and static shear data extends to 250°F and 350°F. It is the preferred choice where maximum gap filling, cold-impact resistance, and extended static shear data are required.
Why is peel adhesion important when selecting a structural bonding tape?
Peel adhesion determines whether the tape maintains contact with the substrate when the assembly is subjected to flexing, vibration, or forces that act to lift the bond line at its edges. In bonded assemblies using glass, metal, or coated substrates, inadequate peel adhesion leads to edge delamination and bond failure. AFTC 5359 delivers 23 lb/in at 90° peel — the highest in this SilverTape set — providing maximum edge retention on high and medium surface energy substrates.
What is the operating temperature range for AFTC 5359?
AFTC 5359 has a minimum temperature resistance of -40°F, a long-term temperature resistance of 248°F, and a short-term temperature resistance of 374°F, as listed on the TDS.
Is AFTC 5359 suitable for cold-environment or impact-sensitive applications?
Yes. The TDS states that AFTC 5359 maintains high impact resistance at temperatures below 0°C, making it suitable for cold-environment structural bonding applications. No specific regulatory compliance standards are stated on the TDS.
How should AFTC 5359 be specified?
Specify grade (AFTC 5359), thickness (0.118"), color (white), compliance requirements, dimensional tolerances, adhesive side (double), liner type (red PE liner), and finished format.
