Adhesives are an important class of industrial polymers with applications ranging from adhesive tape and sticky notes through to resins used in mines. This poster will showcase the development of a new hot-melt adhesive to repair conveyor belts in mines. Any downtime in the production process is very costly. A repair tool of choice is in this case a hot-melt adhesive: it can be applied quickly, and once applied it does not require a long curing time until it has the desired properties that the process demands. Since there are many possible sources of physical and chemical stress in a mining process, the adhesive needs not only to be strong in its adhesive properties and its flexibility, but also very stable against mechanical stress, heat, UV radiation, acids, bases and other aggressive chemicals, mostly hydrocarbons.<br/>The base resin thus needs to be strengthened by the right combination of additives. ATR FT-IR, solid-state NMR and Raman spectroscopies were assessed for their potential to reveal the composition and homogeneity of the final product. The results were used to evaluate the extrusion process used to form the final product, RubbaFIX® (www.rubbafix.com.au).
