WebThe wax appearance temperature (WAT) is the temperature at which the first wax crystals start to form, on cooling of paraffin/solvent systems. There are a number of different WAT determination methods, including: density and viscosity variation, differential scanning calorimetry, laser dispersion, and chromatography. Webmicrocrystalline wax, any petroleum-derived plastic material that differs from paraffin waxes in having much finer and less-distinct crystals and higher melting point and viscosity. Microcrystalline waxes are used chiefly in laminated-paper products, in coatings and linings, and in adhesives, sealing compositions, and various types of polishes. In contrast to …
