Hydrocarbon resins are primarily composed of cyclic, polycyclic or heterocyclic aliphatic and aromatic structures. Hydrocarbon resins are non-reactive thermoplastic binders, but have low MW compared to other conventional thermoplastic binders such as vinyl, acry­lic, and cellulose esters. They are rarely used as sole binders in coatings, but rather as modifiers. In general, hydrocarbon resins have good solubility in non-polar solvents but are insoluble in polar solvents. Being composed of hydrocarbons and free of any reactive groups, their films are resistant to water and chemicals, making them useful as protective coatings, water proofing, hot-melt adhe­sives, floor coatings, and hot-melt road marking paints, to name a few applications. However, their sensitivity to solvents is a primary limitation. Hydrocarbon resins with a high level of unsaturation have a tendency for yellowing upon exposure to UV light and hence are generally required to be formulated with suitable antioxidants and light stabilizers.
