HB Mortar is a chemicall hardening, halogen free, 100% potassium silicate, acid-resistant brick mortar. It is especially suited for the installation and maintenance of linings in acid towers and tanks. HB mortar requires no acid wash and employs a unique, inorganic, patented hardening system, which makes it resistant to sulfation-hydration, crystal growths, and, when cured, water wash out.
HB Mortar offers excellent resistance to acid exposure in the vapour sone of lined pressure vessels.
HB Mortar will not corrode steel substrates as it hardens and does not release HF during the curing process.
HB Mortar is used in the installation of acid-resistant brick work in sulfuric acid plant equipment, chimneys, vessels, towers, floors and other areas where exceptional chemical resistance and physical properties are required.
