DURO-LAST ® A.R.P. MEMBRANE

Description:

Duro-Last® A.R.P. Membrane (black in color) is fabricated from a high tenacity, l ow shrink weft i nserted 18 x 14, 1000 Denier polye ster fabric that has been coated with a proven thermoplastic alloy. This specially formulated permanent thermoplastic alloy does not contain conventional plasticizers that migrate from the coating. It is specially formulated to be c ompa tible with aspha lt-b ased produ cts. It is resistant to ultraviolet rays and microorganisms. The tear and puncture strength of the polyester fabric are superb, and it is impervious to most caustic chemicals, petroleum products, animal fats and acids. It shows no ill effects from either heat or cold.

The Duro-Last A.R.P. Membrane is non-curing to provide excellent weldability for the entire life of the system. A patch, curb, stack or any other necessary additions or alterations can easily be accomplished by heat welding (hot-air) the new Duro-Last membrane\accessory to the existing m embrane. Heat welding (hot-air) is used to bond all field seams. The welds can be made with a hand-held unit or a walker welder. The hot air seaming eliminates the need for chemicals, torches and other unsafe, non-manageable seaming systems.
