Sikaflex®-252 - Elastic adhesive for vehicle assembly bonding

PRODUCT BENEFITS

• Bonds well to a wide variety of substrates
• Capable of withstanding high dynamic stresses
• Good gap-filling properties
• Can be painted
• Vibration-damping
• Electrically non-conductive
• Listed under NSF - Proprietary Substances
  and Nonfood Compounds (black and white)

Usage

Sikaflex®-252 is suitable for assemblies that are subject to dynamic stresses. Suitable substrate materials are timber, metals, particularly aluminum (including anodized components), sheet steel (including phosphated, chromated and galvanized components), metal primers and paint coatings (2-component systems), ceramic materials and plastics. Seek manufacturer’s advice before using on plastics that are prone to stress cracking. This product is suitable for professional experienced users only. Test with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.
