Single-sided adhesive tapes

A single-sided adhesive tape consists of a backing coated with adhesive on one side only. It can be used to hold, protect, mask, insulate, close, mark, or assemble different elements. Its performance varies depending on the material of the backing, the type of adhesive, and the conditions under which it is applied.

A single-sided adhesive tape has one sticky surface and generally remains visible after application. It is particularly used for packaging, masking, protection, or insulation. A double-sided adhesive tape has two sticky surfaces and allows for a more discreet attachment of two materials together.

The choice mainly depends on the application surface, the level of adhesion required, and the duration of application. It is also important to consider temperature, humidity, mechanical stress, exposure to UV or chemicals, as well as removal conditions. The width, thickness, and length of the roll must also be suitable for the application.

The backing partly determines the flexibility, strength, and uses of the adhesive tape. Paper is particularly used for masking, while polyester, polyimide, PTFE, fabric, or plastic films meet more technical constraints. The backing should be chosen according to the temperature, mechanical strength, and expected precision.

An acrylic glue generally offers good resistance to ageing, UV and temperature variations. A rubber glue often provides quick initial adhesion on many materials. A silicone glue is more suitable for high temperatures and certain difficult surfaces. The choice should always be made according to the substrate and the conditions of use.

The surface must be clean, dry and free from dust, oils or residues that may reduce adhesion. The tape should then be applied with consistent pressure to ensure good contact with the substrate. On a rough, fragile or difficult-to-adhere surface, a preliminary test allows for checking adhesion and the quality of removal.

It is advisable to specify the materials involved, temperature conditions, duration of application, level of adhesion and the type of removal desired. DERFI can study the application, conduct tests and propose a packaging, masking, protection, insulation tape or a suitable technical adhesive. Custom cutting and transformation solutions can also be considered.
