AFTC AM9608 is the 0.031″ grade in the AFTC Acrylic Coating 66 LSE series, providing increased bondline thickness and higher peel adhesion compared to the thinner AM9606 grade. Like all Coating 66 grades, it is formulated with Acrylic Coating 66 for adhesion to difficult low surface energy substrates — ceramics, silicones, Teflon, powder-coated metals, clearcoats, and ceramic car paints — that standard Acrylic Coating 47 grades are not designed to bond.
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.
AM9608 achieves a 90° peel adhesion of 18 lb/in per ASTM D3330, a dynamic shear strength of 97 lb/in² per ASTM D1002, and a tensile strength of 105 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 AM9608 from AM9606 and AM9611 in the AFTC Acrylic Coating 66 LSE series?
AM9608 at 0.031" provides higher peel adhesion (18 lb/in) than AM9606 (16 lb/in) with a dynamic shear of 97 lb/in² — lower than AM9606's 104 lb/in² but maintaining the same tensile strength of 105 lb/in². Compared to AM9611 (0.047"), AM9608 is thinner with lower peel adhesion (18 vs. 26 lb/in) and higher tensile strength (105 vs. 94 lb/in²). AM9608 is suited for applications requiring a thicker bondline than AM9606 with strong tensile performance.
Why is peel adhesion important for acrylic foam tape selection?
Peel adhesion at 90° measures the resistance of the bond to delamination forces — the load mode most relevant when assemblies flex, vibrate, or experience differential thermal movement. For LSE substrates, the Acrylic Coating 66 adhesive system is specifically formulated to maximize adhesion on these difficult surfaces. AM9608 achieves a 90° peel adhesion of 18 lb/in per ASTM D3330.
What is the operating temperature range for AM9608?
AM9608 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 AM9608 suitable for automotive or regulated environments?
No compliance standards are specified on the manufacturer's TDS for AM9608. 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 AM9608 be specified?
Specify grade (AM9608 / H-O part number SRMAM9608), thickness (0.031" ±15%), 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.
