PRODUCT DESCRIPTION:
These resins are most popular in domestic and foreign markets. With rosin as basic raw material, it is fabricated through bleaching, esterification, stabilization treatment and other processes. RC-80P, RC-85B and RC-90 series,etc. characterized by moderate viscosity, light color and good stability, are more cost-effective products and especially applicable to SBS and EVA hot melt adhesives. Good compatibility with EVA is their notable feature.
