Web10.5.2.8 Hot Melt Adhesives. Hot melt adhesives are 100% solid materials that are applied from the melt. They are one-part, solvent-free thermoplastic adhesives that are solid at room temperature and a low to medium viscosity (750 to 10,000 centipoise) adhesive at dispensing temperatures (typically greater than 195°C). WebHence, different compounds tend to have different melting points. A pure, nonionic, crystalline organic compound usually has a sharp and characteristic melting point (usually 0.5-1.0 C range). A mixture of very small amounts of miscible impurities will produce a depression of the melting point and an increase in the melting point range.
