  • Sikaflex®-292i

    Sikaflex-292i is a non-sag one component polyurethane adhesive of thixotropic, paste-like consistency which cures on exposure to atmospheric moisture to form a durable elastomer. Sikaflex-292i exhibits excellent adhesive properties and a high degree of mechanical strength. Sikaflex-292i meets the low spread of flame requirements set out by the International Maritime Organization (IMO).

     

    Use

    Sikaflex-292i is suitable for structural joints in marine constructions which will be subjected to high dynamic stresses. Suitable to bond metals, particularly aluminum (including anodized finishes), metal primers and paint coatings (2-c systems), or ceramic materials, plastics such as GRP (unsaturated polyester resin), ABS, etc.

    Characteristics and Advantages

    • 1-C formulation
    • Very Low VOC according to US EPA Method 24
    • No added solvents
    • Elastic
    • Can be over-painted
    • 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
