  2. Brasso - Wikipedia

    en.wikipedia.org/wiki/Brasso

    Brasso has also been used to polish out scratches in plastics: It has been used to polish CDs, DVDs, screens, and pools to repair scratches. It is a mild solvent and an extremely fine abrasive, so when applied to the reflective surface of the disc and rubbed radially (in straight lines between the edge and centre), it can smooth scratches and reduce their effect.

  3. Phenylmercury acetate - Wikipedia

    en.wikipedia.org/wiki/Phenylmercury_acetate

    Phenylmercuric acetate was used as a catalyst during commercial 3M Tartan brand polyurethane flexible floor manufacture. That flooring became popular for public buildings, especially school gymnasia , in the 1950s through the 1970s; and traces of the catalyst remained detectable in Idaho public schools as late as 2006.

  4. Tumble finishing - Wikipedia

    en.wikipedia.org/wiki/Tumble_finishing

    A well-chosen speed for stone polishing causes the rocks within the barrel to slide past each other, with the abrasive grit between them. The result of this depends on the coarseness of the abrasive, and the duration of the tumble. Typically, a full tumble polish from rough rock to polish takes 3–5 weeks, and is done in a minimum of 3 steps.

  5. Polishing (metalworking) - Wikipedia

    en.wikipedia.org/wiki/Polishing_(metalworking)

    The condition of the material at hand determines what type of abrasive will be applied. The first stage, if the material is unfinished, starts with a rough abrasive (perhaps 60 or 80 grit) and each subsequent stage uses a finer abrasive, such as 120, 180, 220/240, 320, 400 and higher grit abrasives, until the desired finish is achieved.

  6. Self-healing material - Wikipedia

    en.wikipedia.org/wiki/Self-healing_material

    Tris-maleimide (3M) and tetra-furan (4F) formed a polymer through DA reaction and, when heated to 120 °C, de-polymerized through RDA reaction, resulting in the starting materials. Subsequent heating to 90–120 °C and cooling to room temperature healed the polymer, partially restoring its mechanical properties through intervention.

  7. Quench polish quench - Wikipedia

    en.wikipedia.org/wiki/Quench_polish_quench

    Quench polish quench (QPQ) is a specialized type of nitrocarburizing case hardening that increases corrosion resistance. It is sometimes known by the brand name of Tufftride, Tenifer or Melonite. [ 1 ]
