PENNCOAT™ 401 Lining

Silicon Epoxy Lining

PENNCOAT 401 Lining is a two component room temperature cured silicon based polymeric lining. On concrete, it is applied to 20 – 25 mils, in two 10 – 12.5 mil WFT (wet film thickness) coats. On steel it is installed in two coats at a recommended thickness of 14 – 16 mils WFT (2 x 7 – 9 mils coat). It offers the chemical and temperature resistance of inorganic silicon chemistry with the ease of application and cost effectiveness of conventional organic linings. PENNCOAT 401 is a unique thermosetting silicon polymer which cures with conventional epoxy chemistry yielding highly cross-linked polyether linkages. The absence of problematic hydroxyl, and ester groups makes PENNCOAT 401 resistant to a broad range of corrosive chemicals, including 98% sulfuric acid, and chlorinated solvents. PENNTROWEL™ Epoxy Primer is recommended for concrete substrates. Consult Corrosion Engineering specification CES-264 for complete installation details.
