Selecting Antioxidants for Adhesives & Sealants

Antioxidants for Hot-melt Adhesives Hot-melt adhesives and the components used in their manufacture are generally solid or highly viscous at room temperature. As a result, hot-melt adhesives are exposed to elevated temperatures, which are required to melt the components, during both formulation and end use.

The hot melt adhesive in the form of a film or web is heated by IR heaters and fed into the nip in between the two substrates as shown in Fig. 14.19. One substrate may be supported, and the hot melt adhesive may be powdered from a powder scatterer or the substrate may be pre-printed with adhesive powder.

Hot-melt adhesive - Wikipedia

Hot melt adhesive ( HMA ), also known as hot glue, is a form of thermoplastic adhesive that is commonly sold as solid cylindrical sticks of various diameters designed to be applied using a hot glue gun. The gun uses a continuous-duty heating element to melt the plastic glue, which the user pushes through the gun either with a mechanical trigger

Sustainable Raw Materials in Hot Melt Adhesives: A Review

As hot melt adhesive uses no solvent, it provides a solution to environmental concern. Hot melt adhesives were introduced to the market in the 1950s, and then have become increasingly important in the adhesive segment. HM adhesive covers 15% - 21% of the global volume of production and consumption of adhesives.

Feasibility of Processing Hot-Melt Pressure-Sensitive

Hot-melt pressure-sensitive adhesive (HMPSA) is an environmentally benign adhesive which is typically processed without solvent in industries. However, casting solution method is commonly used for experimental purposes in the lab for convenience. Therefore, seven types of solvent with different polarities, including toluene as the most commonly used solvent, were investigated in this work to
