The need for a long-lasting, seamless, liquid applied, waterproof membrane, designed specifically for flat roof restoration has been evident for a long time. Superior Polymers Inc. has answered this requirement with the development and exhaustive testing of Dura 500 Liquid Applied Roof Membrane.
DURA 500, is a liquid applied, high tensile, seamless, waterproof roof membrane that provides permanent restoration for built-up roofing, rolled asphalt, EPDM, TPO, Hypalon®, modified bitumen, and other roofing surfaces. Until recently, we did not offer a version of this product for sloped metal roofing, due to the self-levelling nature of the coating. As of June 2018, new formula DURA 500 has been modified with a rheology agent to accomodate all sloping metal roofs as well as roof parapets and exterior walls of wood, masonry and metal. The product is a single part emulsion based on SEBS technology (styrene-ethylene-butylene-styrene), also known as thermoplastic elastomer (TPE), and is engineered to provide a service life of well over 20 years. Cold temperature shipping or storage will not harm this coating. DURA 500 is the ultimate, long life, seamless protective membrane and waterproofing solution for flat roofs. Dura 500 exceeds the elongation and tensile strength properties of most mechanically applied membranes.
DURA 500 cures to a tough, impact and abrasion resistant membrane with an amazing tensile strength of 1905 psi. Unaffected by ponding water, UV from sunlight or temperature extremes, DURA 500 can be applied in humid or cold conditions, allowing for an extended application season. Uncured product will not wash off with overnight rain or heavy dew.
DURA 500 can be applied by high pressure airless spray, brush or roller. DURA 500 exceeds US Energy Star and ASTM D6083 requirements for solar reflectivity, and can reduce air conditioning costs by as much as 30%, depending on building design and geographic location. Heat stress on the roof structure is virtually eliminated. Flexible, reflective and impact resistant, DURA 500 provides a highly cost effective solution to re-roofing.
Reflected light can greatly improve solar panel efficiency on flat or low-sloped roofs. Most water-based acrylic coatings will absorb moisture and deteriorate in the presence of standing water or ice. Dura 500 on the other hand, remains unaffected by these conditions and remains flexible, even in extreme cold temperatures. The product self-levels and forms a strong, seamless, membrane with over 90% reflectivity. Dura 500 can be spray applied after solar panel mounts are installed, assuring a tight waterproof seal.
