EPDM is excellent for both new construction and roof replacement. It is capable of withstanding temperature variations from -62F to 300F without cracking or deteriorating. EPDM offers high tensile strength, extreme elongation capabilities, and is generally compatible with other materials used in most roofing applications.
EPDM Rubber has had a long history of superior performance
in hoses, molded products, tires and roofing membranes. For example,
the radiator hoses in our cars and the gaskets on our freezer
doors are made of EPDM rubber and show the broad temperature range
the product can handle. EPDM Roofing Membranes also have more
than 30 years of successful history. EPDM is relatively inexpensive,
simple to install, and fairly clean to work with when compared
to conventional materials. There are not the strong odors and
fumes either. The product is very stable and the resulting characteristics
of Liquid EPDM such as flexibility, weatherability and chemical
resistance are determined by it. Liquid EPDM therefore, can be
described as a new form of an old and well-established rubber
polymer. Now you can take advantage of the
same benefits to weather-tight your leaks. Liquid EPDM forms a
100% seamless layer. No
other product can match the durability of EPDM Liquid Roof.
EPDM EPDM is essentially immune to the effects of ultraviolet
and ozone and is one of the best water barriers known. EPDM EPDM
also has the broadest temperature tolerance, and is not water-soluble
even in the uncured state. Even if you happen to get a unexpected
rain shower just after you applied Liquid EPDM there's no need
to worry; Liquid EPDM will not wash off.
Liquid EPDM Rubber vs. Neoprene Rubber
EPDM rubber was not available in liquid form until relatively recently so Liquid Neoprene rubber became the material of choice for protecting concrete against both fresh and salt water. The Liquid Neoprene products are simple solvent solutions or water based emulsions and therefore have low solids content and relatively low molecular weights. These limitations made multiple coat applications necessary and required top coating with other polymers to prevent ultra violet degradation.
The development of Liquid EPDM Rubber resulted in a high solids, two components chemically reactive product capable of polymerizing at ambient temperatures 55 F (13 C) and higher. This product can be applied at a 30 mil dry film (.76 mm) in a single application because of the high solids content. Its chemical cure feature then results in a high molecular weight film with protective and performance properties exceeding those of liquid applied Neoprene films.
Liquid EPDM Rubber can withstand boiling water or live steam and is inherently UV and ozone stable. The product is safer to use because of its higher flash point and the two component packaging permits extended storage at higher temperatures than liquid Neoprene. The non polar characteristic of the EPDM also gives it advantages over Neoprene in saltwater environments as well as better resistance to cathodic disbondment. EPDM rubber has poor resistance to oils, fats, waxes and aliphatic solvents but possesses very good resistance to ketone solvents, alcohol, polar compounds, Salts, most acids up to 50 % concentration, alkalies and water.
