Application Instrutions for Adhesive POS Tapes Products

POS Tapes have a large range of tapes and adhesives to cover every needs and individual or company might have.

Below are a few pointers on how to get the best results from any adhesive product you purchase from POS Tapes.


As a general statement, the best temperature for bonding adhesive tapes is between +15°C and +30°C.

Low temperature application is possible for modified adhesive systems, but there may be a compromise on the ultimate bond strength.


The surface of the parts must be clean, dry and free of moisture and condensation.
The surfaces must also be free of oil, fat, dust and other contaminants.
Porous surfaces can be primed to ensure a uniform, stable surface.


The cleaning of the surfaces has to be done with clean cloths together with suitable solvents, like alcohol or ethers, to remove any dust and oil.

For release agents and other contaminants you can use the following solvents: isopropanol-water mixture 50:50, heptane, ethanol, acetone, MEK or other suitable solvents that do not attack the substrate to be bonded. The selected solvent must be checked thoroughly before being used and the safe use of solvents must always be taken into consideration.


Adhesive tapes are pressure sensitive (PSA’s). The initial application pressure is critical to the ultimate performance of the adhesive tape. The target application pressure is 10-15N/cm², which is best provided by a roller or press. When application is only possible by hand, a firm even and overall pressure is essential and is best provided by use of an applicator or rubber based ‘squeegee’.
Firmer adhesive classes (such as pure acrylics) require more initial application pressure than soft ones.

The full bonding power of hard adhesives is attained between 24 and 72 hours, depending upon the substrates, application pressure and the application environment.

Force and Stress

Where possible, avoid leverage of the bonded components for as long as possible after assembly.
Shear and peel forces have to be evenly distributed across the whole of the bonded surface areas. During assembly, permanent shear loads should be avoided, as this will adversely affect the viscoelastic bonding. (e.g. arched, curved or bowed surfaces should be mechanically clamped and held for the bond to be effective)

Suitable Materials 

Typically, good adhesion can be attained on smooth surfaces, for rough surfaces you will also require a thicker tape or alternative product format.

Good or easily bonded surfaces are: metals, high energy surfaces such as smooth wood, ABS polycarbonate, PMMA, hard PVC, wood, stone and glass.

Critical Materials

Guidance should be sought for low energy surfaces, particularly plastics, where plasticisers may be present, which can adversely affect the bond. These critical surfaces such as polyethylene, polypropylene, rubbers, powder coats, silicones, polyurethane, Teflon and varnishes should be tested for performance and compatibility prior to specifications or recommendations for use are made.


The storage of adhesive tapes should be at room or ambient temperature and at 50-70% relative humidity and out of direct sunlight.

Extremes and fluctuations in storage temperature and humidity should be avoided.
