HYDROGRAL G

HYDROGRAL G by DRT is glycerol ester of partially hydrogenated rosin-based tackifier. It is used in butyl rubber-based sealants for double glazing. Also used in pressure sensitive adhesives (hot-melt or solvent-based) and contact adhesives. HYDROGRAL G is compatible with EVA, natural and synthetic rubbers (SIS, SBS, SBR and butyl) and APAO (amorphous polyalpha olefins). This rosin provides oxidation resistance and long-term adhesive performances. The shelf life is 6 months.
