AFTC 5305 is the thinnest grade in the 53xx series of clear, conformable, low-temperature double-sided acrylic foam tapes at 0.019″. It is specifically formulated for bonding applications that occur in low temperature ranges — where conventional acrylic foam tapes may lose tack — and features very high initial tack that enables 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.
AFTC 5305 is supplied with a paper liner — distinguishing it from all other grades in the 53xx series, which use a red PE liner.
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 5305 from AFTC 5304, the adjacent thin clear grade?
AFTC 5305 is 0.019" thick with a paper liner, specifically designed for low-temperature bonding with very high initial tack and plasticizer resistance. AFTC 5304 is 0.015" thick with a red PE liner, specifically designed for applications requiring a highly transparent bond where stress corrosion cannot occur. Both share 17 lb/in peel adhesion and 88 lb/in² dynamic shear. The selection between them turns on whether the primary requirement is low-temperature/initial-tack performance (5305) or transparent/stress-corrosion-free bonding (5304).
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 (17 lb/in for AFTC 5305) 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 5305?
AFTC 5305 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 5305 suitable for assemblies exposed to plasticizers or outdoor weathering?
Yes. The TDS states that AFTC 5305 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 5305 be specified?
Specify grade (AFTC 5305), thickness (0.019"), color (clear), compliance requirements, dimensional tolerances, adhesive side (double), liner type (paper liner), and finished format.
