A hydrocarbon resin is a C5/C9 aromatic hydrocarbon that is used in industrial applications. It has a tackifying effect and is suitable for use in paint, printing ink, adhesives, rubber and other areas where tackiness is required.
Generally, the petroleum resins are not used independently, but have to be used together with other types of resins as promoters, adjusting agents and modifiers in hot-melt adhesive, pressure-sensitive adhesive, hot melt road marking paint, rubber tires etc.
