AFTC SC11B
AFTC SC11B is a double sided, closed cell acrylic foam tape with a permanent Acrylic Coating 40 adhesive system on both faces, available at 0.047″ thickness. It is designed for structural cladding applications on high and medium surface energy substrates — including plastics, glass, steel, aluminum, and ceramics — and is capable of withstanding wind, temperature extremes, sway, and vibration by addressing both static and dynamic loads through its elastic properties. The tape delivers a 90° peel adhesion of 23 lb/in and is rated for long-term service up to 212°F and short-term exposure up to 320°F.

AFTC SC11B is a Structural Cladding Tape — a designation that distinguishes it from general purpose AFTC grades by its specific design for façade and cladding assemblies subject to structural loading. Its elastic construction allows it to absorb shock and deflection from wind, thermal movement, sway, and vibration, addressing both static and dynamic loads simultaneously.
The tape’s ability to fill gaps and voids prevents the ingress of dirt, cleaning chemicals, and moisture, and contributes to clean, consistent joint lines in cladding assemblies. It uses the same Acrylic Coating 40 adhesive as general purpose 53-series grades and targets high and medium surface energy substrates. Note: all “Black+” tapes have a gray core and black adhesive.
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; the AFTC line requires up to 72 hours to reach end-strength without primer, which is reduced to approximately 20 minutes with a compatible primer. 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 SC11B from general purpose 53-series grades such as AFTC 5357, which shares the same adhesive?
AFTC SC11B and AFTC 5357 both use Acrylic Coating 40 and target high and medium surface energy substrates. SC11B is specifically designated as a Structural Cladding Tape and is characterized by its elastic properties designed to absorb shock, deflection, wind load, sway, and vibration — addressing both static and dynamic structural loads. It also fills gaps and voids to prevent ingress of contaminants and moisture. At 0.047" with 85 lb/in² dynamic shear, it differs from AFTC 5357 (0.062", 78 lb/in² dynamic shear) in both thickness and mechanical profile.
Why is peel adhesion important when selecting an acrylic foam tape for structural cladding?
Peel adhesion — measured here at 23 lb/in per ASTM D3330 — determines how effectively the tape resists being lifted from the cladding substrate under wind uplift, thermal cycling, or mechanical loading. In façade and cladding applications where the bond line must perform over decades of environmental exposure, maintaining adequate peel adhesion is critical to the long-term integrity of the cladding attachment.
What is the operating temperature range for AFTC SC11B?
AFTC SC11B 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 SC11B suitable for outdoor or UV-exposed environments?
The TDS rates AFTC SC11B as having excellent UV resistance and excellent solvent resistance. It is specifically described as capable of withstanding temperature extremes. No specific regulatory compliance standards are listed on the TDS.
How should AFTC SC11B be specified?
Specify grade (AFTC SC11B), thickness (0.047"), color (Black+), liner type (Red PE), dimensional tolerances, and finished format. Note any primer requirements for lower surface energy substrates and confirm minimum application temperature of 59°F can be met at time of installation.
