RESIDHERE AB 150 is a solvent-free saponified gum rosin subjected to a disproportionation process that converts abietic acid into dehydroabietic acid. This rosin offers exceptional oxidation resistance for use as an additive in the preparation of cement and mortar, providing a decrease in concrete density with nonflammable benefits. RESIDHERE AB 150 can also be used as an emulsifier in the production of rubber polymers, such as nitrile, styrene–butadiene, polychloroprene, and acrylonitrile–butadiene–styrene rubbers. Additionally, RESIDHERE AB 150 can be used as a high-quality dust suppressor in the mining industry.
