PENNCOAT™ 401 MR Lining (CE-264A)

Mat Reinforced Silicon Epoxy Lining

PENNCOAT 401 MR Lining is a 40-50 mil mat reinforced room temperature cured silicon based polymeric lining for concrete substrates. PENNCOAT 401 is applied in two 10-12 mil WFT (wet film thickness) coats over mat reinforced PENNTROWEL Epoxy Primer. 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. When the crack bridging advantages of a glass mat reinforcement are desired, PENNCOAT 401 MR (Mat Reinforced) utilizes a 1 oz chopped strand glass mat reinforcement in the primer layer. Consult Corrosion Engineering specification CES-342 for complete installation details.
