Application fields:

Sikaflex®-522 adheres well to a wide variety of substrates and is suitable for elastic sealing and bonding applications both indoors and outdoors.

is suitable for applications in air ventilation areas and accidental contact with food.

Suitable substrate materials include wood, glass, metals, metal primers and paint coatings (two-component systems), ceramic materials, and plastics.

Ask the manufacturer for advice and perform tests on the original substrates before using Sikaflex®-522 on materials prone to stress cracking.

This product is suitable only for experienced professional users.

Tests must be conducted with real substrates and conditions to ensure adhesion and material compatibility.

Chemical Resistance:
Sikaflex®-522 is generally resistant to fresh water, seawater, diluted acids, and diluted caustic solutions; temporarily resistant to fuels, mineral oils, greases, and vegetable and animal oils; not resistant to organic acids, glycol alcohol, concentrated mineral acids, and caustic solutions or solvents.

Overpainting:
Sikaflex®-522 can be best painted within the film formation time.
If the painting process takes place after the sealant has formed a film, adhesion may be improved by treating the joint surface with Sika® Aktivator-100 or Sika® Aktivator-205 before painting.
If the paint requires a baking process (> 80 °C), the best performance is achieved by allowing the sealant to fully cure first.
All paints must be tested by performing preliminary trials under production conditions.
The elasticity of paints is usually lower than that of sealants.
This may cause cracking of the paint in the joint area.
