Foreverest™ CHRD400, Colorless Hydrogenated Rosin Derivatives

Oct 19, 2015

Colorless Hydrogenated Rosin Derivatives

Foreverest™ CHRD400 is all most highly hydrogenated, a derivative of colorless hydrogenated rosin. Hydrogenation reduces oxygen uptake in the resin and greatly improves its color. They do not only have good adhesion and wide compatibility rosin resins possess, but also have the clarity and stability comparable to hydrogenated hydrocarbon resins.

Hydrogenation Degree and Color Stability

The hydrogenation degree can be determined by the content of Tetrahydro-resin acid/ester (THRA) and Dihydro-resin acid/ester (DHRA). CHRD show high level of hydrogenation (see Table1), which represents the latest hydrogenation technology in China, with an eltra-light color and excellent color stability.(see Table1)
