- Bonding to low surface energy substrates requiring the maximum gap-filling bondline thickness in the AFTC Acrylic Coating 66 LSE series
- Attachment of automotive trim and body components to LSE-coated surfaces where a thick, highly conformable bondline is required
- Bonding to silicones, Teflon, powder coatings, clearcoats, and ceramic car paints where a 0.09″ bondline is specified
- Double-sided structural bonding on LSE substrates combining the thickest foam core in the Coating 66 range with 27 lb/in peel adhesion
- UV- and solvent-resistant bonding in exterior automotive applications involving difficult or coated surfaces with significant surface variation
Common industries: Automotive, Industrial Manufacturing, Electronics, Construction.
AFTC AM9623 is the thickest grade in the AFTC Acrylic Coating 66 LSE series at 0.09″. Like all Coating 66 grades, it uses Acrylic Coating 66 for adhesion to difficult low surface energy substrates — ceramics, silicones, Teflon, powder-coated metals, clearcoats, and ceramic car paints. The tape is supplied in black (gray core with black adhesive) with a Red PE liner.
The TDS notes that viscoelastic properties allow tensions in the adhesive seam to be distributed, enabling very durable bonding. Its thick construction provides the greatest gap-filling capability in the Coating 66 series while maintaining high peel adhesion and dynamic shear performance.
AM9623 achieves a 90° peel adhesion of 27 lb/in per ASTM D3330, a dynamic shear strength of 97 lb/in² per ASTM D1002, and a tensile strength of 81 lb/in² per ASTM D897. Static shear strength at 72°F is 1,000 grams, at 200°F is 500 grams, and at 250°F is 250 grams (per 1/2 in² for 10,000 minutes / 7 days) per ASTM 3654. The tape offers excellent solvent and UV resistance.
Shelf life is 18 months; store in original packaging in a dry environment between 39.2°F and 100.4°F. Minimum recommended application temperature is 59°F. Minimum bond line pressure required is 14.5 psi.
What differentiates AM9623 from AM9620 and other AFTC Acrylic Coating 66 LSE grades?
AM9623 is the thickest grade in the AFTC Coating 66 series at 0.09", providing the greatest gap-filling capability in the range. Its peel adhesion of 27 lb/in matches AM9615 and AM9620, while its tensile strength of 81 lb/in² is the lowest in the Coating 66 series — consistent with the trade-off between increasing thickness and tensile performance. Dynamic shear of 97 lb/in² remains high relative to the thicker grades.
Why is peel adhesion important for acrylic foam tape selection?
Peel adhesion at 90° measures the resistance of the bond to delamination forces acting at an angle to the bonded surface — the primary mode of bond failure when assemblies flex, vibrate, or experience differential thermal expansion. On LSE substrates, where surface energy inherently limits adhesion, Acrylic Coating 66 is specifically formulated to maximize bond strength on these difficult surfaces. AM9623 achieves a 90° peel adhesion of 27 lb/in per ASTM D3330.
What is the operating temperature range for AM9623?
AM9623 has a minimum temperature resistance of -40°F, a long-term temperature resistance of 194°F, and a short-term temperature resistance of 248°F.
Is AM9623 suitable for automotive or regulated environments?
No compliance standards are specified on the manufacturer's TDS for AM9623. The TDS describes the tape as designed for automotive applications and specifically for LSE substrates including ceramic car paints, clearcoats, silicones, and Teflon.
How should AM9623 be specified?
Specify grade (AM9623 / H-O part number SRMAM9623), thickness (0.09" ±10%), adhesive system (Acrylic Coating 66 / LSE), liner type (Red PE), substrate type and surface preparation requirements, bond line pressure (minimum 14.5 psi), primer requirements if applicable, dimensional tolerances, and finished format.
