254M
254M is a double-coated acrylic tape with 1.3 mil Acrylic (I630) adhesive on each side of a 0.5 mil PET film carrier, delivered on a 5.5 mil 74# poly-coated kraft liner for an 8.6 mil total thickness. The balanced high-tack, moderate-shear adhesive system provides 60 oz/in adhesion to steel at 24-hour dwell (both sides) and shear hold exceeding 7 days, with resistance to oils, plasticizers, and UV for durable service across extreme temperatures.

254M is a general-purpose double-coated acrylic tape constructed with 1.3 mils of Acrylic (I630) adhesive coated on each face of a 0.5 mil PET film carrier, yielding a 3.1 mil adhesive-plus-carrier profile and an 8.6 mil total stack including the 5.5 mil 74# poly-coated kraft liner.
The adhesive is a high-tack, moderate-shear formulation that delivers symmetric bonding performance from either face — making 254M a versatile choice for bonding and laminating across a wide range of substrate pairings including cloth, vinyl, cork, paper, and both rigid and flexible plastics.
Adhesion to steel develops from 40 oz/in initial (1 mil PET backing) to 60 oz/in at 24-hour dwell on both adhesive sides, with 70 oz/in initial values when tested with 4 mil aluminum foil. Shear adhesion holds for more than 7 days under PSTC-107 conditions.
The adhesive offers resistance to oils, plasticizers, and UV, and exhibits excellent performance across extreme temperatures — making the tape appropriate for mounting displays, signs, posters, mirrors, nameplates, decorative wall products, and paper splicing applications. Both the PET carrier and the kraft liner are conformable, and the carrier provides dimensional support that aids in processing and application.
What differentiates 254M from 256M?
254M and 256M share the same Acrylic (I630) adhesive, PET carrier construction, and liner, but differ in adhesive thickness: 254M carries 1.3 mils of adhesive per side (8.6 mil total), while 256M carries 2 mils per side (10 mil total). The thinner 254M profile is preferred where minimal bondline thickness is required and standard adhesive wet-out is sufficient; 256M is preferred where greater adhesive mass improves contact on less ideal surfaces.
Why is peel adhesion important when selecting this tape?
For double-coated tapes with PET carriers, peel adhesion measures the real-world bond strength of each adhesive face against the substrate. The TDS reports initial and 24-hour dwell values on both the exposed and liner sides of 254M, confirming symmetric bond performance (60 oz/in at 24 hours from either face) — important for applications where bond orientation or assembly sequence varies.
What is the operating temperature range for 254M?
The TDS describes the product as having excellent extreme temperature performance but does not publish specific continuous or maximum service temperature values. Contact H-O Products for guidance on specific thermal service conditions.
Is 254M suitable for UV-exposed or plasticizer-containing environments?
Yes. The TDS states the adhesive is resistant to oils, plasticizers, and UV, making it a suitable selection for mounting and lamination applications in environments where standard acrylic adhesives would degrade. No specific regulatory compliance standards are listed on the TDS for this material.
How should 254M be specified?
Specify grade (254M), adhesive thickness per side (1.3 mils), carrier (PET), liner (74# poly-coated kraft), compliance requirements, dimensional tolerances, and finished format.
