Definitions
- the invention relates to protective coatings for a surface of a roof. More particularly, the invention relates to polymer and rubber based materials in a solvent system for application to a roof surface.
- the coating solution of the invention is non-flammable.
- Basement, foundation, and roof waterproofing is a critical aspect of the construction of new buildings and maintenance of existing buildings.
- the waterproofing process generally involves applying a composition to a wall and roof surface to impart water resistant properties.
- Prior art coatings included asphalts dissolved in a solvent which are sprayed onto a wall or a roof. It is sometimes common to apply a protective board over the coating for facilitating water drainage and/or providing additional insulation.
- basement wall and roof surface coatings require a variety of properties in order to be considered satisfactory. These cured coatings should be strong, have good elasticity, and be able to be applied uniformly to the surface of a wall or roof. While asphalt based compositions have performed satisfactorily, polymer based compositions are also particularly useful for waterproofing. Since polymer based coatings usually have more than one solid ingredient in the formulation, it is important that all ingredients be chemically compatible to avoid separation of the polymer components from the solution resulting in loss of the desirable properties of the solution. Such separation can cause loss of elasticity, strength, tack, and water resistance.
- a satisfactory coating should also provide a consistent, uniform coating on the wall or roof surface.
- the solvent is believed to be related to the consistency of the coating applied to the wall or roof surface. Coating that runs down the wall or do not level properly on a roof surface during application may lead to weak spots in the cured coating. The solvent also affects the drying rate of the coating.
- Solvent systems used in prior art coatings are generally highly explosive and flammable.
- U.S. Pat, No. 5,352,531 to Roberts recommends using combinations of an aliphatic petroleum distillate, such as LACOLENE sold by Ashland Chemical Company, and toluene. Such a solvent has a flash point of about 18°F.
- U.S. Pat. No. 5,932,646 to Roberts uses a solvent that is a blend of petroleum distillates, preferably naphthenic distillates, and heptane.
- a solvent recommended in this patent is sold by UNOCAL Linder the name Lactol Spirits. This solvent has a flash point of about 17°F.
- Elastomeric, emulsion-based coatings which includes water-based acrylic polymer coating systems, currently dominate the roof coating market.
- Oil-based products have been almost completely replaced by water based products due to their volatile organic content (VOC).
- Oil-based products have historically not been deemed suitable for roof coatings because of their need for a carrier solvent that typically is a VOC material and composes 40% to 60% of the coating formulation.
- the Environmental Protection Agency (EPA) oversees the "Energy Star” program. Energy Star is an international standard for energy efficient consumer products. It was first created as a United States government program in 1992.
- a roof coating In order for a coating to receive the "Energy Star Approval," for example, a roof coating must maintain a reflectance of over "65" after three years of outdoor weathering.
- the reflectivity requirement is based on the fact that a white, reflective coating will reflect the heat produced by the sun and dramatically lower the amount of heat developed on the roof surface of the building. The less amount of heat that is produced by the roof will typically result in lower air conditioning costs and a significant reductions in electrical usage which is generated by highly polluting coal fired plants.
- one aspect of the invention is to provide an elastomeric waterproofing coating that is nonflammable and may be considered an environmentally acceptable and bio-preferred product, and that when applied to a surface of a roof, will result in a uniform and consistent coating upon curing.
- the invention provides a composition of matter for waterproofing a surface of a roof
- the composition includes a hydrocarbon resin, a block copolymer selected from the group consisting of styrene-isoprene-styrene block copolymers, styrene-butadiene-styrene block copolymers, and styrene-ethylene/butylene-styrene block copolymers and mixtures thereof, and a solvent system including at least one chlorinated organic solvent and at least one vegetable oil.
- a composition of matter for waterproofing a surface of a roof includes a hydrocarbon resin, a block copolymer, a solvent system including at least one chlorinated organic solvent and at least one vegetable oil, and a ultra-violet reflective pigment.
