Description:
Duro-Last® A.R.P. Membrane (black in color) is fabricated
from a high tenacity, low shrink weft inserted 18 x 14, 1000
Denier polyester 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 compatible with asphalt-based products. 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 membrane. 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.
