SIKAFLEX 252 WHITE - CARTRIDGE 300 ML
Sikaflex 252 is a non-sag 1-c polyurethane adhesive of stiff, paste-like consistency that cures on exposure to atmospheric humidity to form a durable elastomer.
Characteristics
- 1-C formulation
- Elastic
- Can be overpainted
- Good gap-filling properties
- Capable of withstanding high Dynamic stresses
- Vibration-damping
- Non-corrosive
- Electrically non-conductive
- Bonds well to a wide variety of substrates
Application
- Suitable for structural joints that will be subjected to dynamic stresses
- Suitable sub-strate materials are timber, metals, particularly aluminium (incl. ano-dized components), sheet steel (incl. phosphated, chromated and zinc-plated components), metal primers and paint coatings (2-c systems), ceramic materials and plastics. Seek manufacturer’s advice before using on plastics that are prone to stress cracking
