- Structural bonding of high and medium surface energy plastic components in low-temperature service environments where greater bond-line thickness is required
- Attachment of glass elements to metal or composite frames in assemblies subject to cold climate exposure
- Bonding of aluminum and steel substrates where differential thermal expansion between dissimilar materials must be accommodated at low temperatures
- Full-surface bonding of thin or textured substrates, including ceramics, where conformability and a tension-free bond are required
- Replacement of mechanical fasteners in fabricated assemblies where sub-zero end strength and a thicker bond line are design requirements
Common industries: general manufacturing, glazing and fenestration, transportation, construction, signage and display.
AFTC 5353 is a double sided acrylic foam tape using Acrylic Coating 41 on both faces — a formulation specifically suited to bonding high and medium surface energy substrates in low-temperature environments. It accommodates differential thermal expansion between dissimilar materials and allows full-surface, tension-free bonding of thin or textured substrates.
At 0.062″, it is thicker than the AFTC 5351 grade, providing greater gap-filling capability while sharing the same low-temperature performance focus, adhesive system, and mechanical properties. Very good plasticizer resistance is noted as a product characteristic.
The tape demonstrates excellent resistance to solvents and UV exposure. As a pressure sensitive adhesive, a minimum bond line pressure of 14.5 psi applied by hand roller or mechanical presser is required for full adhesion. For low surface energy substrates, primer use is recommended; without primer the AFTC line requires up to 72 hours to reach end-strength, while a compatible primer reduces this to approximately 20 minutes. Shelf life is 18 months when stored in original packaging in a dry environment between 39.2°F and 100.4°F.
What differentiates AFTC 5353 from AFTC 5351, which shares the same adhesive system?
AFTC 5353 and AFTC 5351 share identical adhesive chemistry (Acrylic Coating 41), density (50 lb/ft³), temperature ratings, and all mechanical values. AFTC 5353 is Gray at 0.062" thickness versus White at 0.047" for AFTC 5351 — providing greater gap-filling capability. Color and thickness are the differentiating factors between these two grades.
Why is peel adhesion important when selecting an acrylic foam tape?
Peel adhesion — measured here at 22 lb/in per ASTM D3330 — determines how effectively the tape resists being peeled or lifted from a bonded substrate under service loading. For assemblies operating in low-temperature environments, the retention of adequate peel adhesion at or below 0°C is particularly critical, as many adhesive systems lose bond strength significantly at sub-zero temperatures.
What is the operating temperature range for AFTC 5353?
AFTC 5353 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 AFTC 5353 suitable for outdoor or UV-exposed environments?
The TDS rates AFTC 5353 as having excellent UV resistance and excellent solvent resistance, and specifically notes excellent end strength at temperatures below 0°C. No specific regulatory compliance standards are listed on the TDS.
How should AFTC 5353 be specified?
Specify grade (AFTC 5353), thickness (0.062"), color (Gray), liner type (Red PE), dimensional tolerances, and finished format. Note any primer requirements for low surface energy substrates and confirm minimum application temperature of 59°F can be met at time of bonding.
