Universal Rosin Resin Series RC-80/RC-85/RC-90/RC-100/RC-120-Guangxi Choris Chemical Co.,Ltd.

Commodity name: Universal Rosin Resin Series RC-80/RC-85/RC-90/RC-100/RC-120
Commodity ID: 991300754360590336

These resins are most popular in domestic and foreign markets. With rosin as basic raw material, it is fabricated through bleaching, esterifiction, stabilization treatment and other processes. RC-80, RC-85, RC-90 and RC-100, 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. RC-120 and RC-120L, with superior viscosity and good stability, are particularly suitable for high-grade varieties with high requirements on initial and lasting adhesion properties.
