- Bonding to low surface energy substrates including silicones, Teflon, powder coatings, clearcoats, and ceramic car paints where a thick bondline and high peel adhesion are required
- Attachment of automotive trim and body components to LSE-coated surfaces where a 0.078″ bondline with high dynamic shear is specified
- Gap-filling bonding to medium and low surface energy plastics in automotive and industrial assemblies
- Double-sided structural bonding combining 27 lb/in peel adhesion and 99 lb/in² dynamic shear on LSE substrates
- UV- and solvent-resistant bonding on exterior automotive applications involving difficult or coated surfaces

AFTC AM9620 is the 0.078″ grade in the AFTC Acrylic Coating 66 LSE series, providing greater bondline thickness than the AM9615 grade while maintaining the same 90° peel adhesion of 27 lb/in and offering higher dynamic shear strength. 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.
AM9620 achieves a 90° peel adhesion of 27 lb/in per ASTM D3330, a dynamic shear strength of 99 lb/in² per ASTM D1002, and a tensile strength of 84 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 AM9620 from AM9615 and AM9623 in the AFTC Acrylic Coating 66 LSE series?
AM9620 at 0.078" shares the same peel adhesion as AM9615 (27 lb/in) but provides higher dynamic shear strength (99 vs. 89 lb/in²) at a thicker bondline, making it better suited for applications where shear resistance alongside gap-filling is required. Compared to AM9623 (0.09"), AM9620 offers marginally higher dynamic shear (99 vs. 97 lb/in²) and tensile strength (84 vs. 81 lb/in²) at slightly less thickness.
Why is peel adhesion important for acrylic foam tape selection?
Peel adhesion at 90° measures the resistance of the bond to delamination forces — the primary failure mode when assemblies flex, vibrate, or experience differential movement. On LSE substrates, where surface energy inherently limits adhesion, Acrylic Coating 66 is formulated to maximize bond performance on these difficult surfaces. AM9620 achieves a 90° peel adhesion of 27 lb/in per ASTM D3330.
What is the operating temperature range for AM9620?
AM9620 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 AM9620 suitable for automotive or regulated environments?
No compliance standards are specified on the manufacturer's TDS for AM9620. 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 AM9620 be specified?
Specify grade (AM9620 / H-O part number SRMAM9620), thickness (0.078" ±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.
