PENNCOAT™ 600 Membrane

60 mil Mylar Faced Sheet Membrane

PENNCOAT 600 Membrane is a 60 mil (1.5 mm) thick prefabricated self adhesive reinforced sheet laminate membrane. It is constructed of a woven fiberglass core that is sandwiched between layers of polymer modified high tack rubberized asphalt with an integral chemical resistant Mylar top film. An embossed release film is incorporated onto the back of the sheet for easy release without tears or splits. PENNCOAT 600 is easily rolled into place over properly prepared surfaces that have been primed with PENNCOAT 601. Each roll is 50 ft (15.2 m) in length x 4 ft (1.2 m) in width for easy handling on the jobsite. Consult Corrosion Engineering specification CES-144 for complete installation details.


PENNCOAT 600 Membrane may be applied to concrete or steel substrates as an underlying membrane to overlayments of acid proof brick and polymer concrete construction. It is used for severe chemical applications where the reliability of a sheet membrane system is preferred over conventional liquid applied membrane systems, or where the use of hot asphalt membrane systems is not feasible. The Mylar top coat integrated into PENNCOAT 600 makes it suitable for chemical environments that exceed the limitations of asphalt based systems, such as solvents or acid/solvent combinations.

Typical applications include: floors, trenches, vessels, sumps, manholes, vessel linings, pump pads, bases, and tank piers.


• Prefabricated sheet insures uniform membrane thickness
• Excellent value - economical installed cost compared to other membrane systems
• Excellent chemical resistance - suitable for solvents and acid/solvent combinations
• Easy handling and installation on jobsite
• High elongation within service temperature range of -20°F – 200°F (-28°C – 93°C).
