AFTC AM9316
AFTC AM9316 is a 0.062″ thick, double-sided closed cell acrylic foam tape designed for structural bonding of steel, aluminum, and select plastics in vehicle manufacturing applications. It delivers the highest 90° peel adhesion in the AM93 series at 18 lb/in, with dynamic shear strength of 82 lb/in² and tensile strength of 79 lb/in², and operates across a temperature range of -40°F to 248°F long-term and 374°F short-term. The tape is formulated to absorb differential thermal expansion between dissimilar bonded materials and provides good plasticizer resistance when used in combination with a primer.

- Structural bonding of dissimilar metals in automotive body assembly where maximum gap accommodation and differential thermal expansion absorption are required
- Attachment of glass and glass/epoxy panels to steel or aluminum vehicle structures with larger bondline clearances
- Bonding of anodized and coated aluminum components to vehicle frames and attachment points requiring high peel retention
- Joining of galvanized or stainless steel parts in vehicle manufacturing assemblies with surface irregularities or gap variation
- Structural tape bonding on vehicle components requiring primer-assisted plasticizer-resistant bonds with maximum conformability
Common industries: Automotive manufacturing, transportation, specialty vehicle assembly.
AFTC AM9316 is the thickest grade in the AM93 series of high-performance double-sided acrylic foam tapes at 0.062″, designed for bonding dissimilar materials — including steel, aluminum, glass, glass/epoxy, and coated or anodized metals — in modern vehicle manufacturing. The acrylic adhesive foam core is closed cell and carries a permanent adhesive system on both faces, protected by a red PE liner.
The additional thickness provides maximum conformability and gap-filling capability across the series, and the tape delivers the highest 90° peel adhesion of all AM93 grades at 18 lb/in.
The tape maintains high impact resistance at sub-zero temperatures and 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, and 750 grams at temperatures from 150°F through 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 AM9316 from thinner grades in the AM93 series?
AFTC AM9316 is the thickest grade in the AM93 series at 0.062" and delivers the highest 90° peel adhesion of all grades at 18 lb/in. The greater thickness provides maximum conformability and gap-filling capability across the series, making it the preferred choice where surface gaps are largest or where the highest peel retention at bond edges is required.
Why is peel adhesion important when selecting a structural bonding tape for automotive applications?
Peel adhesion determines whether the tape maintains bond integrity when the assembly is subjected to flexing, vibration, or peeling forces — all common in vehicle structures. A tape with insufficient peel adhesion can initiate delamination at joints, particularly at substrate edges and contours. AFTC AM9316 delivers 18 lb/in at 90° peel — the highest in the AM93 series — providing maximum edge retention on the irregular and curved surfaces typical of automotive assemblies.
What is the operating temperature range for AFTC AM9316?
AFTC AM9316 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 AM9316 suitable for automotive manufacturing environments?
Yes. AFTC AM9316 is specifically designed for bonding steel, aluminum, and select plastics in modern vehicle manufacturing. It provides good plasticizer resistance in combination with a primer and maintains high impact resistance at sub-zero temperatures. No additional regulatory compliance standards are stated on the TDS.
How should AFTC AM9316 be specified?
Specify grade (AFTC AM9316), thickness (0.062"), compliance requirements, dimensional tolerances, adhesive side (double), liner type (red PE liner), and finished format.
