AFTC 2510
AFTC 2510 is a 0.039″ thick, single-sided conformable acrylic foam tape built on a closed cell acrylic core with a printable ionomer backing, designed for difficult sealing of joints and seams on irregular surfaces. It delivers 90° peel adhesion of 14 lb/in and operates across a temperature range of -40°F to 203°F. The ionomer backing is paintable, abrasion resistant, and UV resistant, supporting long-term performance in exposed exterior environments.

- Sealing of joints and seams on motorhomes and recreational vehicles requiring conformability over fasteners and irregular surfaces
- Repair and weatherproofing of roof and gutter penetrations, holes, and tears
- Railcar roof sealing and structural seam repair in transportation maintenance applications
- Bonding over rivets, screws, and contoured edges where tape must follow irregular surface geometry without bridging
- Exterior sealing applications requiring a paintable surface finish after tape installation
Common industries: Transportation, recreational vehicle manufacturing and repair, building and construction, railcar maintenance.
AFTC 2510 is a conformable, single-sided acrylic foam tape engineered for sealing applications where the tape must follow contours, edges, and fastener geometry without lifting or bridging. The closed cell acrylic core forms the structural body of the tape, and the permanent acrylic adhesive system is specifically formulated to allow overlapping tape joints while maintaining a continuous, uninterrupted seal.
The ionomer backing combines flexibility with toughness and abrasion resistance, and it accepts paint — making AFTC 2510 suitable for exterior installations where a cosmetic topcoat will be applied after sealing. The tape is rated for excellent UV resistance and excellent water resistance per the TDS.
Surface preparation requirements follow the AFTC line standard: light to moderate contamination should be removed with IPA; heavily contaminated surfaces require MEK, Heptane, or Acetone followed by an IPA wipe; raw aluminum must be abraded prior to bonding. A minimum bond-line pressure of 14.5 psi is required. Full end-strength is achieved within 72 hours; use of H-O Products Primer 33 or Primer 101 reduces cure to approximately 20 minutes.
What differentiates AFTC 2510 from thicker grades such as AFTC 2520?
AFTC 2510 is 0.039" thick — approximately half the thickness of AFTC 2520 at 0.079". The reduced thickness makes AFTC 2510 the preferred choice where a lower profile is required, joint gaps are tighter, or where material weight and bulk must be minimized, while still delivering the same tensile strength (45 lb/in²) and the same broad temperature range.
Why is peel adhesion important when selecting a conformable sealing tape?
Peel adhesion determines whether the tape maintains continuous contact with the substrate under mechanical loading, thermal cycling, and long-term environmental exposure. For outdoor sealing applications on vehicles, roofing, and transportation structures, a tape that loses peel adhesion will allow moisture infiltration at the bond line. AFTC 2510 delivers 14 lb/in at 90° peel, providing a durable seal on the contoured and irregular surfaces typical of these applications.
What is the operating temperature range for AFTC 2510?
AFTC 2510 is rated for a minimum temperature resistance of -40°F and a maximum temperature resistance of 203°F, as listed on the TDS.
Is AFTC 2510 suitable for exterior or UV-exposed environments?
Yes. The TDS rates AFTC 2510 as having excellent UV resistance and excellent water resistance, and the ionomer backing is paintable for applications requiring a finished exterior appearance. No specific regulatory compliance standards are stated on the TDS.
How should AFTC 2510 be specified?
Specify grade (AFTC 2510), thickness (0.039"), compliance requirements, dimensional tolerances, adhesive side (single), liner type (PET release liner), and finished format.
