    en.wikipedia.org/wiki/Solvent_bonding

    Solvent bonding differs from adhesive bonding, because the solvent does not become a permanent addition to the joined substrate. [4] Solvent bonding differs from other plastic welding processes in that heating energy is generated by the chemical reaction between the solvent and thermoplastic, and cooling occurs during evaporation of the solvent ...

    The matrix is created by the other ingredients in the semi-permanent mold release. Applications of semi-permanent mold release vary from every cycle to once daily applications depending on the compound being molded and the design and quality of the mold. Silicone-based rubber products, however, require a non-silicone based releasing agent.

    The mixture consists of polyvinyl acetate (PVAC) AYAC, ethylene acrylic acid (EAA) copolymers A-C 540, and 580, antioxidants Irganox 1076 or 1035, dry pigments, marble powder, and other additives which were all melted together. This wax resin is a better substitute to wax-resins because wax collects dust and dirt and make the fill noticeable.

    It is supplied as a powder with liquid methyl methacrylate (MMA). Although PMMA is biologically compatible, MMA is considered to be an irritant and a possible carcinogen. PMMA has also been linked to cardiopulmonary events in the operating room due to hypotension. [42] Bone cement acts like a grout and not so much like a glue in arthroplasty ...

  8. Sodium silicate - Wikipedia

    en.wikipedia.org/wiki/Sodium_silicate

    The largest application of sodium silicate solutions is a cement for producing cardboard. [1] When used as a paper cement, the sodium silicate joint tends to crack within a few years, at which point it no longer holds the paper surfaces cemented together.

  9. Plastic welding - Wikipedia

    en.wikipedia.org/wiki/Plastic_welding

    Solvent welding is a common method in plastics fabrication and used by manufacturers of in-store displays, brochure holders, presentation cases and dust covers. Another popular use of solvents in the hobby segment is model building from injection molded kits for scale models of aircraft, ships and cars which predominantly use polystyrene plastic.
