Piccolastic™ hydrocarbon resins are homopolymers of purified styrene. They are low in color and are available in softening points ranging from 5-125°C. Piccolastic™ A5 hydrocarbon resin is unusual as it is a true low molecular weight liquid resin that will perform as a functional plasticizer. Piccolastic™ A75 and D125 are used in hot melt adhesives, especially in polychloroprene-based solvent adhesives for light-colored leather and plastics. Since Piccolastic™ hydrocarbon resins are pure styrene they generally do not impart tack at room temperature but will function as tackifiers in hot melt adhesives when molten. In styrenic block copolymers Piccolastic™ resins will associate only with the end-blocks and will modify the melt properties of the polymer but will not contribute to tack properties.
