Double-sided tapes allow you to firmly attach objects without damaging the surface, and they work in climate-controlled environments. They are also more convenient than using screws and nails, which require extensive curing time and clean up.
The kind of adhesives, carriers, and primers used in a tape determine its main characteristics. These factors should be considered to make the right choice.
1. Adhesive Strength
Double-sided adhesive tape is often used wherever a permanent connection needs to be made or when fastening with screws or drilling just isn’t possible. This type of tape is ideal for sticking posters, pictures, frames and stickers to walls or furniture. It is also commonly used for attaching hooks and other types of hardware to walls.
Choosing the right adhesive for your application starts with evaluating the substrates to be joined. Then you need to consider the desired performance requirements. These might include the ability to withstand specific types of stress (tensile, shear, cleavage or peel).
A double-sided tape’s adhesive strength depends on the surface it is being applied to and how much pressure is being applied. Additionally, it’s important to ensure the surface is clean and dry before applying tape. Traces of dust, dirt, grease or even moisture will contaminate the adhesive and significantly reduce its strength. This will be evident when the tape fails to bond or quickly loses its stickiness.
2. Temperature Resistance
Double sided tapes can withstand a range of temperatures. This is important because the adhesive strength of a tape can be affected by its environment. For example, high heat can cause the adhesive to soften past its cohesive threshold. This means that the tape will lose its adhesion.
Colder environments can also negatively affect a tape’s adhesion. This can happen because the tackiness of tape can decrease as it gets cooler. The best option is to choose a specialty low-temperature tape for these types of environments.
Many industrial applications require a high level of temperature resistance. For example, the tapes formulated for use with medical devices need to be able to adhere to skin, while meeting biocompatibility requirements. They also need to be able to withstand a high-temperature range (e.g., up to 180°C). These types of tapes are made to resist a variety of environmental conditions and offer a high level of temperature resistance.
3. Moisture Resistance
If you store double-sided tape in a damp, dusty or extremely hot or cold place for an extended period of time, it will lose its adhesive properties. This is because the moisture in the air will migrate into the surface of the adhesive and cause it to soften.
The surface characteristics of the materials you’re bonding will also impact the performance of your tape. Flat and smooth surfaces, like glass, aluminum and PVC, can use thinner tapes than rough or painted surfaces.
Most tape failures can be avoided by evaluating your job, materials and field conditions and choosing the right tape for the task at hand. Just like you wouldn’t choose a hammer for a saw, it’s important to select the right tape for your project. Doing so will help you avoid the frustration and wasted effort of dealing with failed bonds. This is why we recommend always conducting adhesive testing to prevent the mistakes that can cost you money and time.
4. Resistance to UV Light
Depending on the environment, it’s important to consider how much UV exposure the tape will be exposed to. Exposure to UV light can cause the adhesive layer of the tape to harden or deteriorate, which is something you definitely want to avoid.
Another factor to consider is what sort of chemicals the double sided tape will come into contact with. Certain solvents such as petrol, kerosene or oils can have a detrimental effect on the adhesive. Therefore, choosing a chemical-resistant tape is essential.
There are a variety of different types of double-sided adhesive tape available to suit many different applications and surfaces. From general mounting tapes, to polyethylene foam tape for soundproofing, there’s sure to be a product that suits your needs. The key is knowing your job, materials and field conditions in order to find the right product for your specific requirements. Once you’ve done that, the rest is easy!
