Problems solved by technology

Up to now, existing roofing systems are very labor dependent and require multiple steps.
Existing roofing materials are primarily bituminous based asphaltic substances, and have inherent limitation in their abilities to perform well and over time when exposed to weathering conditions such as U.V exposure, wind, precipitation, temperature extremes and physical shocks.
Contamination problems arise with the use of traditional bituminous based roofing systems, where equipment and clothing eventually are covered with tar.
Substantial costs and labor is required in maintenance and replacement of the said equipment.
Additionally, traditional bituminous based systems require significant labor and machinery to lift materials to the roof surface.
Installation and removal of such system also require significant labor.
Furthermore, traditional roofing systems apply materials at elevated temperature (typically between 450° C.-900° C.) and results in injury, fire and worker safety issues.
Significant amount of Volatile Organic Compound (V.O.C) are present in traditional systems which are environmental and health issues.
Traditional roofing systems, when exposed to hot weather conditions, are prone to heat degradation and tearing.
They may also stick to worker's footwear or equipment thus rendering roof servicing inconvenient.
Furthermore, asphaltic substances are directly affected by the price of world oil commodities
Typical membrane-based roofing products exhibit “wind lift” drawbacks due to the fact that their point of adhesion to the substrate are limited.
The placement of sheets is laborious.
They are also prone to tearing and perforation as the thickness is typically 3 mm or less.
These systems are subject to abrasion, puncture, and thermal cracking caused by tension and compression.
Recent polymeric sheet membranes (E.P.D.M, P.V.C, bituminous modified and other) are complex to apply, and require many joints which are leak prone and subject to failure when tensile forces result from thermal expansion and contraction.
Roofing systems employing shingles all suffer from leakage due to “wind lift”, curling and water back-up.

Coal Tar-Epoxy Composition

[0104]The coating composition described in table 1, below was prepared in accordance with the following protocol:[0105]The 10-20 crumbs was mixed in proportion with buffings (90) and mixed mechanically until mixture was uniform. The approximate time required was about 2 minutes.[0106]The coal tar derivative was added to the DGEBA resin in proportion and mixed till uniform. The approximate time required was about 2 minutes.[0107]The Hardener was added to DGEBA resin and coal tar and thoroughly mixed by mechanical stirring until total distribution. The approximate time required was about 3 minutes.[0108]The rubber mixture was added to the mixture of hardener DGEBA resin and coal tar while agitating, until mixture uniform. The approximate time required was about 3 minutes.[0109]The mixture was applied within 10 minutes.

[0110]The % amount of each component in table 1 as well as the other examples below represent weight % on the basis of the total composition we...

Heavy Oil-Monofunctional GE-Epoxy Composition

[0112]The coating composition described in tables 2 to 4, below were prepared in a similar manner as for example 1, except that the heavy oil and monofunctional GE were added in place of coal tar derivative.

example 3

Epoxy Composition

[0113]The coating composition described in tables 5 and 6, below were prepared in a similar manner as for example 1, except that the step of coal tar addition to the DGEBA resin and accompanying mixing was absent.
