Structural adhesive tapes –
an alternative to traditional adhesives?
Structural adhesives form bonds that can support loads and bear stress. As such, they are popular in the engineering sector to bond different materials such as metal, composites, and plastic. Structural adhesives can also improve manufacturing processes as they are easier and quicker to apply compared to installing fasteners or creating welds.
However, in their liquid form, structural adhesives have their limitations. They create processing challenges as they transgress bond lines and provide uneven coverage after curing. Structural adhesives turn relatively straightforward bonding into complex, time-heavy processes as they require clamping and fixing until the adhesive bond is set.
This is where structural adhesive tapes come to excel, offering more freedom of design, high ease of use, and safer processing.
Why choose structural adhesive tape?
Depending on the requirements of your application, structural adhesive tapes can represent a more efficient solution while still forming strong, reliable bonds between different substrates. Liquid structural adhesives require mixing, curing, and clamping. By contrast, structural tapes are simple to apply, withstand harsh environments, and are cleaner to use, with no dripping or overflow. Structural tapes also have the advantage of providing uniform thickness throughout the joint.
Typical applications of our structural adhesive tapes
At tesa, our structural tape solutions are widely used in the automotive industry for powertrain applications that demand extreme temperature and chemical resistance. Generally, structural adhesive tapes can reduce weight, improve performance, and enhance aesthetics.
In the electronics sector, they provide outstanding resistance against chemicals, impacts, temperature, and humidity. Typical applications include component and frame mounting, FPC bonding and stiffening, as well as bonding of soft goods and accessories.
In addition, structural adhesive tapes can be used for permanent bonding of chip modules into the cavity of substrates, which is crucial for all smart card manufacturers to ensure the cards function properly in daily applications.
