7744-12
7744-12 is a single-sided acrylic transfer tape consisting of a 3.8 mil acrylic (I627) adhesive layer on an 11.3 mil 12-point poly-coated kraft liner. Formulated specifically for low surface energy (LSE) substrates and foam bonding, it delivers 106 oz/in adhesion to steel at 24-hour dwell, 118 oz/in loop tack, and >40 hours of shear adhesion at 72°F. The thick adhesive layer provides excellent edge wrap resistance in foam bonding applications, with a service temperature range of −30°F to 220°F.

7744-12 is a single-sided acrylic transfer tape engineered for bonding to low surface energy (LSE) substrates including foams, polyolefins, and similar difficult surfaces. The construction pairs a 3.8 mil acrylic (I627) permanent adhesive with an 11.3 mil 12-point poly-coated kraft release liner.
The unusually thick adhesive layer — significantly greater than standard transfer tapes — provides the compliance and wet-out required to anchor effectively on foam surfaces and textured LSE materials, and delivers excellent edge wrap resistance in foam-to-substrate bonding applications.
The adhesive exhibits excellent initial tack with a loop tack value of 118 oz/in, combined with high peel strength (106 oz/in to steel at 24-hour dwell) and medium shear performance (>40 hours at 72°F). Long-term aging characteristics are excellent, and the adhesive offers chemical and plasticizer resistance, supporting durability in service environments where standard acrylic adhesives would degrade.
The rigid 12-point kraft liner aids processing and application by providing stiffness during handling and die-cutting. Laminating temperature is 68°F to 100°F, and service temperature spans −30°F to 220°F. Shelf life is 12 months from date of shipment when stored at 40–60% humidity and 60°F to 80°F.
What differentiates 7744-12 from standard acrylic transfer tapes?
7744-12 is formulated specifically for low surface energy substrates and foam bonding, distinguishing it from general-purpose acrylic transfer tapes optimized for polar surfaces. Its 3.8 mil adhesive thickness — significantly greater than most transfer tapes — provides the compliance and wet-out required for reliable foam bonding, delivers excellent edge wrap resistance, and enables durable adhesion to polyolefins and other LSE materials where standard acrylics typically underperform.
Why is peel adhesion important when selecting this tape?
Peel adhesion confirms whether an adhesive can actually anchor to a difficult substrate. For 7744-12, the 106 oz/in adhesion to steel at 24-hour dwell verifies strong interfacial bonding, while the 118 oz/in loop tack demonstrates excellent initial contact wet-out — both critical for LSE and foam bonding where bond development must be rapid and complete.
What is the service temperature range for 7744-12?
7744-12 has a service temperature range of −30°F to 220°F, with a recommended laminating temperature of 68°F to 100°F.
Is 7744-12 suitable for chemical or plasticizer-exposed environments?
The TDS rates the adhesive as having chemical and plasticizer resistance, supporting use in environments where standard acrylic adhesives would degrade. No specific regulatory compliance standards are listed on the TDS for this material.
How should 7744-12 be specified?
Specify grade (7744-12), adhesive thickness (3.8 mils), liner (12-point poly-coated kraft), target substrate (particularly noting any LSE materials or foam bond surfaces), compliance requirements, dimensional tolerances, and finished format.
