Copaltite for Pulp and Paper
Copaltite seals pulp and paper plant steam connections, digester joints, chemical process lines, and heat exchanger flanges against steam, acids, alkalis, and all pulp and paper process chemicals. Its resistance to both acids and mild alkalis — along with its -315°F to 1500°F range — makes it the standard maintenance sealant for pulp and paper facilities across the UAE, GCC, and Middle East.
Why Pulp and Paper Plants Rely on Copaltite
Pulp and paper manufacturing involves a uniquely aggressive chemical environment — high-pressure steam for cooking and drying, strong acids for bleaching and chemical recovery, caustic alkalis in the kraft process, and high-temperature process fluids throughout the plant. Every joint, flange, and connection in this environment must resist the full range of these media simultaneously, often at elevated temperature and pressure.
Frequently Asked Questions
Yes. Copaltite resists both acids and mild alkalis — covering the full range of chemical process media in pulp and paper manufacturing, from acid bleaching sequences to caustic kraft process streams.
Yes. Copaltite Cement Form is used on high-pressure digester manhole covers and connection flanges — providing a reliable seal under the cooking pressure and temperature conditions of the kraft and sulphite pulping processes.
