654M
654M is a double-coated acrylic LSE tape with 2 mils of Acrylic (I626) adhesive on each side of a 0.5 mil PET film carrier, supplied on a 5.5 mil 74# poly-coated kraft liner for a 10 mil total thickness. Engineered for automotive interior applications on low surface energy substrates including ABS, TPO, powder-coated paints, PE, PP, and numerous foams, the tape passes SAE J-1756 automotive fogging (@ 100°C) and SAE J-1351 odor testing. Peel adhesion reaches 180 oz/in (liner side, 2 mil aluminum foil) with shear hold exceeding 7 days.

654M is a high-tack, high-shear double-coated acrylic LSE tape engineered specifically for automotive interior bonding applications. The construction pairs 2 mils of Acrylic (I626) adhesive on each face of a 0.5 mil PET film carrier, yielding a 10 mil total thickness with the 5.5 mil 74# poly-coated kraft liner.
The LSE-optimized adhesive bonds effectively to a broad range of automotive interior substrates including ABS, TPO, powder-coated paints, polyethylene (PE), polypropylene (PP), and numerous foam types — materials where standard acrylic tapes typically lack adequate surface compatibility.
Adhesion values are among the highest in the double-coated series: 180 oz/in on the liner side and 165 oz/in on the exposed side when tested with 2 mil aluminum foil backing, 65 oz/in and 50 oz/in respectively with 1 mil PET backing. Loop tack measures 120 oz/inch on the exposed side and 115 oz/inch on the liner side. Shear adhesion exceeds 7 days under PSTC-107 conditions.
The tape passes two key automotive qualification tests: SAE J-1756 automotive fogging at 100°C (volatile emissions that could condense on interior glass) and SAE J-1351 odor testing — making 654M suitable for automotive OEM interior trim applications where emissions and olfactory characteristics are regulated. Additional features include low flogging, low flammability, and excellent high and low temperature resistance.
The PET carrier supports precision die-cutting, and both the carrier and liner are dimensionally stable during converting.
Compliant with SAE J-1756 (Automotive Fogging @ 100°C) and SAE J-1351 (Odor Test).
What differentiates 654M from other double-coated acrylic tapes?
654M is specifically engineered for automotive interior bonding on low surface energy substrates, combining three key attributes that together are rare in a single product: LSE-optimized Acrylic (I626) adhesive that bonds to ABS, TPO, PP, PE, and foams; automotive-qualified performance (passes SAE J-1756 fogging and SAE J-1351 odor); and aggressive bond strength (up to 180 oz/in). Standard acrylic double-coated tapes typically lack the LSE compatibility or the SAE qualification, or both.
Why is peel adhesion important when selecting this tape?
For LSE substrates common in automotive interiors (TPO, PP, powder-coated surfaces), peel adhesion directly determines whether the adhesive can anchor at all — standard acrylics often fail on these surfaces. The 654M values of 165–180 oz/in on steel with aluminum foil backing, combined with 115–120 oz/inch loop tack, confirm both strong long-term bond strength and rapid initial grab, which matter for automotive assembly-line bonding where immediate dimensional stability is required.
What is the operating temperature range for 654M?
The TDS describes excellent high and low temperature resistance but does not publish specific continuous or maximum service temperature values. Contact H-O Products for guidance on specific thermal service conditions.
Is 654M suitable for automotive interior OEM applications?
Yes. The TDS confirms compliance with SAE J-1756 (Automotive Fogging at 100°C) and SAE J-1351 (Odor Test), the two key OEM qualifications for automotive interior adhesives related to volatile emissions and olfactory characteristics. Low flogging and low flammability are also listed as product features.
How should 654M be specified?
Specify grade (654M), adhesive thickness per side (2 mils), carrier (0.5 mil PET), liner (74# poly-coated kraft), target substrate (confirming LSE type), compliance requirements (SAE J-1756 and/or SAE J-1351 as applicable), dimensional tolerances, and finished format.
