Properties: Special resin for road marking paint(hot melt). It is made in small pellet through esterification by gum rosin, unsaturated binary acid and multi-alcohol, during the reaction, anti-oxidant and optical stabilizer are added. Due to the good stability in storage, prominent heat resistance, low viscosity when molten and odorless nature, the resin is especially suitable for road marking paints as tackifier. Meantime, the paints added with the resin well resist compressing and crafting, resist contamination, dry quick and flow easy. Specifications of LB-1, LB-1A, and LB-2 are as follows.
