Dicyclopentadiene (DCPD)-based hydrocarbon resins are widely used as tackifiers in many applications. In particular, hydrogenated DCPD-based hydrocarbon resins are frequently used in premium hot-melt adhesives (HMAs) and hot-melt pressure-sensitive adhesives (HMPSAs) because of their water-white color and excellent stability to light and heat. Such resins are characterized by their softening point, degree of modification with aromatic olefins and degree of hydrogenation. When the tackifiers are formulated with an elastomeric polymer, these characteristics have a bearing on the adhesive performance.
