  • Adhesive Agent can fail due to three reasons

    Earlier, Shoe Adhesive removed paintwork as it was bald off, so Drew set about inventing a pressure-sensitive band that would not blister paintwork. Other developments saw him blanket cellophane with adhesive and, in 1930, the calm band we are all so accustomed with, was released.
    Since then, the basal attempt of adhesive band accept been activated to other uses. Now there are a adapted and adapted ambit of tapes for adapted applications, including ancestor tape, activity identification tape, plumber's tape, electrician's band and packaging tapes.
    Tapes can now action aegis adjoin electrical current, temperature and the escape of gas or liquid, as in the case of chrism tape, which uses accessible or closed-cell sponges for aegis as able-bodied as the bonding calm of adapted surfaces.
    3. Epoxy (used for potting and metal-metal bonding)
    4. Solvent bonding (used for assembly of low-cost tubing sets)
    Bonding is considered successful when the joined parts act as one material. Bonding is best achieved with compatible materials, clean parts and fresh adhesive.
    Adhesives join parts or surfaces as:
    1. Molecular Bond, where adhesive joins chemically to the substrates
    2. Mechanical Bond, where adhesive grabs onto surface of the substrates (Sometimes etching non-reactive substrate materials or grit blasting metals is required)
    Adhesive Agent can fail due to three reasons: Adhesive Failure (failure due to load on adhesive although bonded to both surfaces)
