The most common reasons for difficulties

Improper cleaning

• Insufficient thorough cleaning
• Improper cleaner

Inadequate preparation of surface and/or tape with regard to surface energy

• See chapter: Guidelines for successful adhering

Tape sizing:

• Ensure a suitable tape surface according to the load assumption.

Tape thickness

• The tape must be applied with a sufficient surface to the basis (uneven surfaces require a greater thickness of tape).
• When adhering different materials, it is necessary to take into account the elongation values 

Inadequate choice of tape type with regard to thermal load

• The choice of EHB tapes according to temperature resistance is between 100 and 220 °C.

Inadequate working conditions

• Choosing a suitable tape for working at low temperatures

Adhering pressure 

• Insufficient pressure does not create sufficient application or adhesion of the tape to the surface (very important for uneven surfaces and lower temperatures).

Premature joint load

• Immediate tape adhesion when following the instructions described above is 50-60% of the final value (80-90%) if using primer/sanding)
• the final value of the adhesive joint occurs after 48 hours (the higher the temperature, the shorter the time).
