Justus Sakti Raya was established in 1982 as the Justus group chemical manufacturing unit, becoming one of the top Unsaturated Polyester Resin (UPR)-YUKALAC producer in indonesia, under license from Showa Highpolymer Co. Ltd. -Japan. Since then, Justus Sakti Raya had increased its production capacity several times (to a total of 24,000 mt/yr), including production expansions covering Metallic Soap/Drier-YUKALIC, Polymer Emulsion (Latex)-YUKASHU and a petrochemical division producing Maleic Anhydride and Fumaric Acid (under license from Lonza Spa-Italy).
Most of our qualified employees are chemists and engineers. With well-equipped laboratories and strict quality control, customers are assured of good and consistent products from Justus. Justus's unique integrated manufacturing capabilities facilitate a strong program of made-to-order items. Since we manufacture many of our own starting materials, we maintain total control over every production process.
