AFTC 5326 is a 0.016″ grade in the AFTC 53-series Acrylic Coating 40 range with several unique characteristics distinguishing it from other grades in the series. It uses a conformable acrylic foam core — designated on the TDS as “Conformable Acrylic Foam” — rather than the standard acrylic adhesive foam core used in other 53-series grades.
The tape is gray rather than white or black, is listed as water resistant and free of bi-metal corrosion concerns, and is noted as a replacement for rivets, screws, spot welds, and liquid adhesives. The product description specifically identifies PVC and ABS as target substrates.
AFTC 5326 achieves a 90° peel adhesion of 18 lb/in per ASTM D3330, a dynamic shear strength of 102 lb/in² per ASTM D1002, and a tensile strength of 97 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, UV, and water resistance and maintains high impact resistance below 0°C, as stated on the TDS.
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 5326 from other 53-series Acrylic Coating 40 grades?
5326 is unique within the 53-series in three ways confirmed on its TDS: its core is designated "Conformable Acrylic Foam" rather than the standard "Acrylic Adhesive Foam Core"; it is gray rather than white or black; and it lists water resistance (Excellent) and no bi-metal corrosion as features — neither of which appears on any other 53-series TDS. It is also the only 53-series grade to explicitly list replacement of rivets, screws, spot welds, and liquid adhesives as a typical application.
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 commonly encountered when assemblies flex, vibrate, or experience differential movement. For high and medium energy substrates including PVC and ABS, Acrylic Coating 40 on a conformable foam core is designed to deliver full-surface, tension-free adhesion. 5326 achieves a 90° peel adhesion of 18 lb/in per ASTM D3330.
What is the operating temperature range for 5326?
5326 has a minimum temperature resistance of -40°F, a long-term temperature resistance of 212°F, and a short-term temperature resistance of 320°F.
Is 5326 suitable for automotive or regulated environments?
No compliance standards are specified on the manufacturer's TDS for 5326. The TDS describes 5326 as a general purpose tape designed for automotive and industrial applications on high and medium energy substrates, with water resistance and no bi-metal corrosion as listed performance characteristics.
How should 5326 be specified?
Specify grade (5326 / H-O part number SRM5326), thickness (0.016" ±15%), color (Gray), core type (Conformable Acrylic Foam), liner type (Red PE), substrate surface preparation requirements, bond line pressure (minimum 14.5 psi), primer requirements if applicable, dimensional tolerances, and finished format.
