- Bonding of high and medium surface energy plastics including PVC and ABS where a black tape is required
- Bonding to glass, steel, aluminum, and ceramics with high initial tack and good plasticizer resistance
- Thin or textured surface bonding where full surface, tension-free adhesion is required
- Double-sided bonding of dissimilar materials subject to differential thermal expansion
- Low-temperature service assemblies requiring maintained impact resistance below 0°C

AFTC 5319 is a 0.025″ grade in the AFTC 53-series general purpose Acrylic Coating 40 range, supplied in black (gray core / black adhesive). It is specifically designed for bonding high and medium surface energy substrates and is capable of absorbing the differing thermal expansions of two different materials. The 53-series is described on the TDS as having a very high initial tack, very good plasticizer resistance, and the adaptability to bond thin or textured surfaces full surface and tension free. The tape is supplied with a Red PE liner.
AFTC 5319 achieves a 90° peel adhesion of 19 lb/in per ASTM D3330, a dynamic shear strength of 96 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 (per 1/2 in² for 10,000 minutes / 7 days) per ASTM 3654. The tape offers excellent solvent and UV resistance and maintains high impact resistance even at temperatures 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 5319 from 5333 (same thickness) and other 53-series Acrylic Coating 40 grades?
5319 and 5333 are both 0.025" Acrylic Coating 40 grades with identical peel adhesion (19 lb/in), dynamic shear (96 lb/in²), and tensile strength (100 lb/in²). The primary distinction is color: 5319 is black (gray core / black adhesive) while 5333 is white. Additionally, 5333 carries a higher density (54 lb/ft³ vs. 52 lb/ft³) and a higher short-term temperature resistance (350°F vs. 320°F).
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. Acrylic Coating 40 is formulated for strong initial tack and durable adhesion on high and medium energy substrates. 5319 achieves a 90° peel adhesion of 19 lb/in per ASTM D3330.
What is the operating temperature range for 5319?
5319 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 5319 suitable for automotive or regulated environments?
No compliance standards are specified on the manufacturer's TDS for 5319. The 53-series is described as a general purpose tape designed for bonding high and medium energy substrates in automotive and industrial applications.
How should 5319 be specified?
Specify grade (5319 / H-O part number SRM5319), thickness (0.025" ±15%), color (Black / gray core, black adhesive), liner type (Red PE), substrate surface preparation requirements, bond line pressure (minimum 14.5 psi), primer requirements if applicable, dimensional tolerances, and finished format.
