Abstract
A composition for applying onto a road surface and methods for making thereof is disclosed. The composition comprises a binder material of at least a styrenic block copolymer and a resin, which can be pelletized. The SBC is selected from a styrene-isoprene-styrene rubber (SIS) and styrene-isoprene/butadiene-styrene (SIBS); or styrene-ethylene/propylene/styrene-styrene (SEPSS), styrene-ethylene/butylene/styrene-styrene (SEBSS) and mixtures thereof. The binder can be used in road marking compositions or surface treatment compositions when combined with other components such as pigments, glass beads, anti-skid media, fillers, waxes, elastomer/plastomer, and plasticizers.
