AFTC AM9808 is the 0.031″ grade in the AFTC Acrylic Coating 91 LSE series, providing greater bondline thickness than the AM9806 grade while maintaining the same dynamic shear strength of 112 lb/in² and tensile strength of 104 lb/in². It is formulated with Acrylic Coating 91 to conform to the highest standards for bonding to powder-coated surfaces, automotive lacquers, and low surface energy materials including PP, PP-EPDM, EPP, and TPE — without the use of a primer. The tape is supplied in black (gray core with black adhesive) with a Red PE liner.
AM9808 achieves a 90° peel adhesion of 16 lb/in per ASTM D3330, a dynamic shear strength of 112 lb/in² per ASTM D1002, and a tensile strength of 104 lb/in² per ASTM D897. Static shear strength at 72°F is 1,000 grams (per 1/2 in² for 10,000 minutes / 7 days) per ASTM 3654. The tape offers excellent solvent and UV resistance and is rated for short-term use to 248°F and long-term to 194°F.
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 AM9808 from AM9806 and AM9811 in the AFTC Acrylic Coating 91 series?
AM9808 at 0.031" provides higher peel adhesion (16 lb/in) than AM9806 (15 lb/in) while sharing the same dynamic shear strength of 112 lb/in² and tensile strength of 104 lb/in². It is the last Coating 91 grade to achieve 112 lb/in² dynamic shear — AM9811 (0.047") drops to 103 lb/in². For applications requiring 0.031" bondline thickness with the highest shear performance in the series, AM9808 is the appropriate grade.
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 encountered when assemblies flex, vibrate, or experience differential movement. For LSE substrates including PP and TPE, Acrylic Coating 91 is formulated to deliver adhesion without priming. AM9808 achieves a 90° peel adhesion of 16 lb/in per ASTM D3330.
What is the operating temperature range for AM9808?
AM9808 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 AM9808 suitable for automotive or regulated environments?
No compliance standards are specified on the manufacturer's TDS for AM9808. The TDS describes the tape as conforming to the highest standards for automotive applications on LSE materials, powder-coated surfaces, and automotive lacquers, and states that it bonds these substrates without the use of a primer.
How should AM9808 be specified?
Specify grade (AM9808 / H-O part number SRMAM9808), thickness (0.031" ±15%), adhesive system (Acrylic Coating 91 / LSE primer-free), liner type (Red PE), substrate type and surface preparation requirements, bond line pressure (minimum 14.5 psi), dimensional tolerances, and finished format.
