SUPER EXCELLENT PERFORMANCE
The hydrogenation degree can be determined by the content of Tetrahydro-resin acid/ester and Dihydro-resin acid/ester. CHRDs show a high level of hydrogenation (see Table 1), which represents the latest hydrogenation technology in China, with an ultra-light color and excellent color stability (see Table 2).

ADVANTAGES OVER OTHER RESINS
Compared to other tackifiers, CHRDs provide an optimum combination of adhesion, clarity, and stability, all important attributes for formulating high-end adhesives. (See Table 3).

END-USE & ALTERNATIVES
Foreverest® Colorless Hydrogenated Rosin Derivatives (CHRDs) are mainly used as tackifiers in adhesives and sealants, especially for acrylic adhesives, while 400 could also be used in soldering fluxes. They are excellent alternatives to Arakawa® products and Eastman® products (see Table 4).
