Description Sikaflex® -521 UV is a onecomponent PUR-Hybrid sealant based on the Sika Silane Terminated Polymer (STP) technology. The product cures on exposure to atmospheric humidity to form a durable elastomer. Sikaflex® -521 UV is manufactured in accordance with ISO 9001 / 14001 quality assurance system and with the responsible care program. Product Benefits - Ageing and weathering resistant - Bonds well to a wide variety of substrates without the need for special pre-treatment - Elastic - Can be overpainted - Can be sanded - Low odor - Non-corrosive - High electrical resistance - Isocyanate- and solvent-free - Silicone- and PVC-free Areas of Application Sikaflex® -521 UV adheres well to a wide variety of substrates and is suitable for elastic sealing and bonding. Suitable substrate materials include timber, metals, metal primers and paint coatings (2-part systems), ceramic materials and plastics. Seek manufacturer’s advice before using on transparent materials that are prone to stress cracking. This product is suitable for professional experienced users only. Tests with actual substrates and conditions have to be performed to ensure adhesion and material compatibility
Cure Mechanism Sikaflex® -521 UV cures by reaction with atmospheric moisture. At low temperatures the water content of the air is generally lower and the curing reaction proceeds somewhat slower (see diagram 1). If Sikaflex® -521 UV is used in combination with a PUR adhesive, the latter must be fully cured before seam sealing with Sikaflex® - 521 UV. Time(days) 0 8 10 Thickness of cure (mm) Diagram 1: Curing speed Sikaflex® -521 UV Chemical Resistance Sikaflex® -521 UV is resistant to fresh water, seawater and proprietary aqueous cleaning agents; temporarily resistant to fuels, mineral oils, vegetable and animal fats and oils; not resistant to organic acids, concentrated mineral acids, caustic solutions or solvents. The above information is offered for general guidance only. Advice on specific applications will be given on request. Method of Application Surface preparation The surfaces must be clean, dry and free from grease, oil, and dust. The adhesion of the sealant can be improved by wiping the joint faces with Sika® Aktivator-205 or possibly applying the appropriate Sika® Primer. Directions for the preparation and treatment of different substrates are given in the appropriate Sika Pre-treatment Chart. Advice on specific applications is available from the Technical Department of Sika Industry. Application Cut off the tip of the nozzle to give desired sealant bead geometry. For satisfactory results the sealant must be applied with a hand-operated cartridge gun, piston type compressed-air gun or pump operated bulk dispensing equipment.
