HYDROGRAL P by DRT is pentaerythritol ester of partially hydrogenated rosin-based tackifier. It is compatible with copolymers, ethylene, vinyl acetate and natural or synthetic rubbers (SIS, SBS, SBR and butyl). This rosin provides excellent resistance to oxidation & aging and long-term adhesive performances. HYDROGRAL P is recommended for hot-melt and solvent-based pressure-sensitive adhesives. The shelf life is 15 months.
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.
