SikaFlex 522 weather-resistant, low-emission universal adhesive sealant black 300 ml/410g PRODUCT BENEFITSHigh ageing and weathering resistantHigh fungicidal resistanceVery low emission and odorBonds well to a wide variety of substrates without the need for special pre-treatmentHigh color stability under UVIsocyanate, solvent, phthalate and silicone-freeMeets hygiene requirements for ventilation and air-conditioning systems and units according VDI 6022 Blatt 1:2011-07ISEGA certificate for foodstuff area usageEC1+ certificate Areas of ApplicationSikaflex®-522 adheres well to a wide variety of substrates and is suitable for interior and exterior elastic sealing and bonding applications. It is suitable for applications in areas of air ventilation and incidental food contact. Suitable substrate materials include timber, glass, metals, metal primers and paint coatings (2-part systems), ceramic materials and plastics. Seek manufacturer’s advice and perform tests on original substrates before using Sikaflex®-522 on materials prone to stress cracking. This product is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility.

Surface treatment depends on the specific nature of the substrates and is crucial for a long lasting bond. Suggestions for surface preparation may be found on the current edition of the appropriate Sika® Pre-Treatment Chart. Consider that these suggestions are based on experience and have in any case to be verified by tests on original substrates. ApplicationSikaflex®-522 can be processed between 5 °C and 40 °C (climate and product) but changes in reactivity and application properties have to be considered. The optimum temperature for substrate and sealant is between 15 °C and 25 °C. Consider that the viscosity will increase at low temperature. For easy application, condition the adhesive at ambient temperature prior to use. Sikaflex®-522 can be processed with manual, pneumatic or electric driven piston guns as well as pump equipment. The skin time is significantly shorter in hot and humid climate. For advice on selecting and setting up a suitable pump system, contact the System Engineering Department of Sika Industry. Tooling and finishingTooling and finishing must be carried out within the skin time of the sealant. It is recommended using Sika® Tooling Agent N. Other finishing agents must be tested for suitability and compatibility prior the use. RemovalUncured Sikaflex®-522 can be removed from tools and equipment with Sika® Remover-208 or another suitable solvent. Once cured, the material can only be removed mechanically.Hands and exposed skin have to be washed immediately using hand wipes such as Sika® Cleaner-350H cleaning towels or a suitable industrial hand cleaner and water. Do not use solvents on skin. OverpaintingSikaflex®-522 can be best painted within the skin formation time. If painting process takes place after the sealant has built a skin, adhesion could be improved by treating the joint surface with Sika® Aktivator-100 or Sika® Aktivator-205 prior to paint process. If the paint requires a baking process (> 80 °C), best performance is achieved by allowing the sealant to fully cure first. All paints have to be tested by carrying preliminary trials under manufacturing conditions. The elasticity of paints is usually lower than that of sealants. This could lead to cracking of the paint in the joint area.
