- Structural bonding of high and medium surface energy plastic components in low-temperature service environments
- 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 is a design requirement
Common industries: general manufacturing, glazing and fenestration, transportation, construction, signage and display.
AFTC 5351 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. Unlike standard Acrylic Coating 40 grades in the 53-series, this tape is characterized by excellent end strength at sub-zero temperatures, making it appropriate for assemblies that must maintain bond integrity in cold service conditions.
It accommodates differential thermal expansion between dissimilar materials and allows full-surface, tension-free bonding of thin or textured substrates. 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 5351 from standard 53-series grades such as AFTC 5355 or AFTC 5357?
AFTC 5351 uses Acrylic Coating 41 rather than the Acrylic Coating 40 used in the 53-series grades, and is specifically designed for bonding high and medium energy substrates in low temperature ranges. Its defining characteristic is excellent end strength at temperatures below 0°C. It also has a slightly lower density of 50 lb/ft³ versus 52 lb/ft³ for the Coating 40 grades, and a peel adhesion of 22 lb/in versus 23 lb/in for comparable 53-series 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 5351?
AFTC 5351 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 5351 suitable for outdoor or UV-exposed environments?
The TDS rates AFTC 5351 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 5351 be specified?
Specify grade (AFTC 5351), thickness (0.047"), color (White), 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.
