Intertape ALF300 is a 3.0 mil dead soft aluminum foil tape with an aggressive pressure-sensitive acrylic adhesive — a self-wound aerospace speed tape used by aircraft MRO operations for chemical paint-stripping masking and as an underlay for PMB blast tape. It is approved to Boeing BAC D6-34501 Rev. H, AMS-T-23397B and USAF T.O. 1-1-8, and is also listed to UL-723, delivering 55 oz/in adhesion to steel and a -30°F to +325°F operating range. It gives instant, water-resistant adhesion, sticks to itself where overlapped, and conforms to curved surfaces without cracking or lifting. Available in aluminum (silver), 1" and 2" x 60 yd rolls, self-wound with no liner.

Frequently Asked Questions
What is Intertape ALF300 used for?
ALF300 is used for masking during chemical paint stripping of aircraft, as an underlay for PMB blast tape in drystripping, for electroplating masking, heat reflection, and sealing duct board, sheet metal ductwork and flexible duct wrap.
Is ALF300 a good alternative to 3M 425?
Yes. Both are dead soft, self-wound aluminum foil tapes with acrylic adhesive. ALF300 adds Boeing BAC D6-34501 Rev. H and USAF T.O. 1-1-8 approvals.
What approvals does Intertape ALF300 carry?
Boeing BAC D6-34501 Rev. H, SAE AMS-T-23397B and USAF T.O. 1-1-8, plus a UL-723 listing.
What is the NSN for Intertape ALF300?
1" x 60 yd is NSN 7510-01-670-5481 and 2" x 60 yd is NSN 7510-01-670-5486.
What is aircraft speed tape?
Speed tape is aluminum foil tape used on aircraft for temporary non-structural repairs, masking and sealing. ALF300 is a self-wound speed tape, so it dispenses straight from the roll with no liner.
Does ALF300 have a liner?
No. ALF300 is self-wound with no release liner, and it adheres to itself where overlapped.
What temperature range is ALF300 rated for?
It is rated from -30°F to +325°F (-34°C to +163°C), with a recommended minimum application temperature of 35°F.
Is ALF300 flame retardant for aircraft interiors?
No. ALF300 is listed to UL-723 but carries no FAR 25.853 approval. Polyken 345SW is the foil tape with FAR 25.853(a).
What sizes and pack quantities does ALF300 come in?
We stock 1" and 2" x 60 yd rolls, sold by the roll, in 3- or 8-roll packs, or by the case (36 rolls for 1", 24 rolls for 2").
What is the shelf life of ALF300?
24 months from date of purchase when stored at 60–80°F and low humidity.
Does ALF300 come with a Certificate of Conformance?
Yes. A free Certificate of Conformance is included with every order.
