AFTC AM9911 is a 0.047″ grade in the AFTC Acrylic Coating 66 LSE series, using Acrylic Coating 66 for adhesion to difficult low surface energy substrates — ceramics, silicones, Teflon, powder-coated metals, clearcoats, and ceramic car paints. It is distinguished from the earlier Coating 66 grades (AM9604–AM9623) by a lower density of 35 lb/ft³ versus the 37 lb/ft³ carried by those grades.
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.
AM9911 achieves a 90° peel adhesion of 27 lb/in per ASTM D3330, a dynamic shear strength of 84 lb/in² per ASTM D1002, and a tensile strength of 100 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 AM9911 from AM9611 and other Acrylic Coating 66 grades at the same thickness?
AM9911 and AM9611 are both 0.047" Acrylic Coating 66 LSE grades, but AM9911 has a density of 35 lb/ft³ versus AM9611's 37 lb/ft³. AM9911 achieves the same 90° peel adhesion as AM9611 (27 lb/in) but with a lower dynamic shear strength (84 vs. 103 lb/in²) and higher tensile strength (100 vs. 94 lb/in²). The lower density of AM9911 reflects a distinct foam construction within the Coating 66 series.
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 failure mode when assemblies flex, vibrate, or experience differential thermal movement. For LSE substrates, Acrylic Coating 66 is specifically formulated to maximize adhesion on these difficult surfaces. AM9911 achieves a 90° peel adhesion of 27 lb/in per ASTM D3330.
What is the operating temperature range for AM9911?
AM9911 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 AM9911 suitable for automotive or regulated environments?
No compliance standards are specified on the manufacturer's TDS for AM9911. 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 AM9911 be specified?
Specify grade (AM9911 / H-O part number SRMAM9911), thickness (0.047" ±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.
