    Instant-Bond Adhesives for Hard-to-Bond Materials

    Image of Product. Front orientation. Instant-Bond Adhesives. Instant-Bond Adhesives for Hard-to-Bond Materials.
    Join plastics that standard instant-bond adhesives can't grip. These adhesives stick to smooth materials, such as polyethylene and polypropylene. Clean and prepare the surface with primer so the adhesive can spread, dry, and gain strength.
    Add an accelerator after the primer and before the adhesive to reach a full-strength bond faster.
    Thick Liquid—Fill larger gaps than thin-liquid adhesives, so they're better for bonding slightly misaligned or uneven surfaces.
    Mil. Spec.—Manufactured and tested to meet strict U.S. military standards for performance and reliability.
