Adhesive strips: when can you use them?
Adhesive strips are materials in the shape of a film with an adhesive mass deposited on top. Given that they are versatile and easy to use, these products are used for joining materials and for a wide variety of technical applications. Here’s a brief but comprehensive overview of the use of adhesive strips in industry.
Double-sided adhesive strips for material assembly
Bonding and the use of double-sided adhesive strips are recent methods of joining materials, constantly improving thanks to advances made by manufacturers.
Assemblies using double-sided adhesive strips have several advantages:
- Using them does not require special technical skills, which is not the case with welding, for example
- They can be permanent or temporary
- They do not damage the materials to be assembled, unlike riveting, screws, or other mechanical methods
- They allow you to create discreet assemblies, sometimes almost invisible, without the need to retouch.
A double-sided strip consists of:
- A central core or support
- An adhesive mass on each side
- A protective film on each side
Which adhesive mass for which material?
There are three families of adhesive masses
- Rubber products: a versatile, low-cost solution, mostly for indoor applications
- Acrylics: enable joining low surface energy materials such as polyethylene or polypropylene. A good choice for permanent outdoor applications
- Silicones: excellent adhesion capacity on silicone materials and a strong resistance to extreme temperatures
Example of semi-structural use of double-sided adhesives
Double-sided adhesives are widely used in several industry fields.
1. Semi-structural outdoor applications:
- Bonding steel stiffeners to road panels
- Mounting and trimming of signs
2. Furniture: bonding foam for seats
3. Construction/urban furniture: mounting aluminum frames, bonding stainless steel, wood, etc.
Single-sided adhesive strips
Single-sided adhesive strips cover a wide range of technical applications. These are different ways to use a single-faced adhesive.
Protection and masking strips are used to protect surfaces temporarily.
Example: canvas adhesives can be used for masking, applying paint, and sanding/blasting operations. Thanks to their high mechanical resistance, they can also be used for repairs.
2. Fill joints/repair
Single-sided adhesive strips with EPDM foam (Ethylene Propylene Diene Monomer) are elastomers that fill in spaces and ensure a tightness seal.
Example: Marking and identification with adhesives. Vinyl adhesives for floor marking, to comply with social distance measures related to COVID-19.
Adhesive strips are widely used in the packaging field.
Example: adhesive Kraft is a paper on which an acrylic, silicone, or rubber adhesive mass is placed.
5. Absorb shocks and vibrations
Foam adhesive strips can be used to absorb vibrations caused by industrial equipment.
6. Isolate surfaces
For more technical applications, Kapton® polyimide adhesive strips provide excellent electrical and thermal resistance. Adhesive strips for electrical insulation are used in the railway industry, for example.
How should you properly apply an adhesive strip?
Before sticking an adhesive strip to a surface, it is crucial to ensure that it is clean, in order to guarantee optimal fixation.
However, as adhesive strips are not meant for structural applications, surface preparation is limited to degreasing the surfaces to be joined.
Adhesive strips are widely used, in industry and in our daily lives, for non-structural and semi-structural applications.
