- Low-temperature bonding of high and medium surface energy plastics and transparent plastics where maximum gap accommodation and highest peel adhesion in the 53xx series are required
- Full-surface, tension-free bonding of thin or textured substrates with significant surface variation in assemblies exposed to plasticizer migration
- Bonding of glass and glazing components in cold-environment manufacturing or installation conditions requiring maximum conformability
- Structural attachment of coated and anodized aluminum components with larger bondline clearances requiring long-term resistance to weathering, UV yellowing, and chemical exposure
- Applications on stainless steel and galvanized steel requiring high impact resistance below 0°C at the thickest available bondline in the 53xx series
Common industries: Glazing, display fabrication, automotive assembly, architectural metalwork, industrial assembly.
AFTC 5315 is the thickest grade in the 53xx series of clear, conformable, low-temperature double-sided acrylic foam tapes at 0.059″. It is specifically formulated for bonding applications that occur in low temperature ranges and features very high initial tack for immediate bond engagement on first contact. Very good plasticizer resistance ensures long-term bond integrity in assemblies where plasticizer migration from adjacent materials is a concern.
The excellent adaptability of the formulation allows thin or textured substrates to be bonded full surface and tension free. The acrylic adhesive foam core is closed cell and carries a permanent adhesive system on both faces, protected by a red PE liner.
AFTC 5315 delivers the highest peel adhesion in the 53xx series at 20 lb/in, consistent with the behavior of thicker acrylic foam grades. The tape maintains high impact resistance at sub-zero temperatures and exhibits very good sealing properties, vibration damping, and very good resistance to weathering, aging, UV/yellowing, chemicals, and plasticizers, resulting in excellent long-term stability per the TDS.
It also exhibits excellent UV resistance and excellent solvent resistance. Static shear strength is 1,000 grams per 1/2 square inch held for 10,000 minutes (7 days) at 72°F, and 500 grams at 150°F and 200°F. A minimum bond-line pressure of 14.5 psi must be applied in a rolling fashion. Full end-strength is reached within 72 hours; use of H-O Products Primer 33 or Primer 101 reduces this to approximately 20 minutes.
Minimum recommended application temperature is 59°F.
What differentiates AFTC 5315 from thinner grades in the 53xx series?
AFTC 5315 is the thickest grade in the 53xx series at 0.059" and delivers the highest peel adhesion in the series at 20 lb/in. Compared to 5310 (0.039", 75 lb/in² dynamic shear, 18 lb/in peel) and 5308 (0.03", 80 lb/in² dynamic shear, 18 lb/in peel), AFTC 5315 provides the most bondline body and the strongest peel retention, making it the preferred choice where surface gaps are largest, conformability requirements are highest, or where maximum peel performance at bond edges is the primary criterion.
Why is peel adhesion important when selecting a low-temperature acrylic foam tape?
In low-temperature bonding applications, the adhesive must wet out and engage the substrate quickly at reduced temperatures where molecular mobility is lower. Very high initial tack — a key characteristic of the 53xx series — ensures the bond engages on first contact before temperature-driven adhesive stiffening can reduce wetting. Sustained peel adhesion (20 lb/in for AFTC 5315 — the highest in the 53xx series) then ensures the bond maintains edge integrity through the thermal cycling the assembly will experience in service, including the sub-zero impact loads for which the tape is rated.
What is the operating temperature range for AFTC 5315?
AFTC 5315 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, as listed on the TDS.
Is AFTC 5315 suitable for assemblies exposed to plasticizers or outdoor weathering?
Yes. The TDS states that AFTC 5315 has very good plasticizer resistance and very good resistance to weathering, aging, UV/yellowing, and chemicals, resulting in excellent long-term stability. No specific regulatory compliance standards are stated on the TDS.
How should AFTC 5315 be specified?
Specify grade (AFTC 5315), thickness (0.059"), color (clear), compliance requirements, dimensional tolerances, adhesive side (double), liner type (red PE liner), and finished format.
