Tackifying resin HB100, HB120
HB100 and HB120 are a family of light-colored, stable gum rosin pentaerythritol resins. They are developed from rosin as the basic raw material through decolorization, esterification, stabilization and other processes. Among them, HB100 has the advantages of moderate viscosity and good heat resistance, and is especially suitable for economical SBS, EVA hot melt adhesive, hot melt coating and other industries; HB120 also has a high softening point, and is especially suitable for formulating hot melt woodworking glue.
