ABSTRACT:
FIELD OF INVENTION
The present invention relates to compositions useful as a protectant for surfaces including painted surfaces, vinyl surfaces, chrome surfaces, and glass surfaces. This invention is particularly applicable to exposed surfaces on automobiles, as well as surfaces on other vehicles such as motorcycles, trucks, boats, RVs, or stationary articles. It is also applicable for many other hard surface found around the home or garage, including glass surfaces and plastic surfaces. It is highly applicable to surfaces that receive continual exposure to weather, including painted surfaces on buildings, vinyl siding on buildings, and painted or plastic signs. The protectant is water-based, abrasive-free, and virtually free of organic solvents. Furthermore, the compositions are in the form of liquid that can be sprayed onto a surface by means of a pump spray or aerosol. The compositions are easily applied onto painted or glass surfaces and can be applied to wet or dry surfaces, with minimal wiping, leaving a dust-free, streak-free, glossy finish.
BACKGROUND OF THE INVENTION
Traditionally, the steps in waxing/polishing an automobile have been (1) wash the car, (2) dry the car, (3) apply and buff the wax/polish, (4) allow the wax/polish to dry, (5) remove powdery residue from the surface. In contrast, the steps in using the protectant of this invention are simply (1) wash the car, (2) spray protectant onto the wet car and dry the car. The protectant requires no further effort such as buffing and there is no powdery residue to remove. The drying of the car is enough to level the protectant of this invention to a streak-free, glossy finish. Therefore, this is the only wax-containing product that does not require abrasives and does not leave dried residues that need to be removed.
In the past, polishes have required one or more abrasives to level the wax film when it is being applied and during buffing. If the abrasive is eliminated, the result has been a smeary or streaked appearance on the surface. Furthermore, as the solvents evaporate in these types of products, most of the wax and other hydrophobic components such as silicone compounds, are extracted into the dried powdery residue and trapped there. Therefore, wiping off the dried on residues removes much of the wax and other actives in these products. Furthermore, UV protectants could not be effectively incorporated in these products since much of the UV absorbers would be trapped into the residues that are wiped off.
U.S. Pat. No. 5,288,314 discloses a polish for cleaning metallic and fiberglass surfaces, such as automobile, truck and boat bodies, and for providing a protective film on the surface. The polish comprises water in an amount between about 40.0 to about 75.0 percent, a solvent in an amount between about 12.0 to about 35.0 percent, a rheological additive in an amount between about 0.30 to about 1.0 percent, an ultraviolet light absorber in an amount between about 0.05 to about 0.50 percent, a dye in an amount between about 0.0005 to about 3.0 percent, a first silicate in an amount between about 5.0 to about 15.0 percent, dimethylpolysiloxane in an amount between about 0.50 to about 6.0 percent, a silicone resin solution in an amount between about 0.10 to about 3.0 percent, oleic diethanol amide in an amount between about 0.50 to about 2.0 percent, a second silicate in an amount between about 0.10 to about 3.0 percent, and a bactericide in an amount between about 0.05 to about 0.20 percent, by weight of the total polish.
In addition to the effort involved in removing the dried film of such compositions, there are other disadvantages. Paint technology has changed significantly and at present, abrasives are in many cases too aggressive and tend to scratch the painted surface. However, simply removing the abrasives from formulations is not a viable alternative. Abrasives aid in the even distribution of wax and silicone film forming components thereby reducing the tendency to streak. Removing them tends to increase streaking which is not desirable from a consumer's point of view. Furthermore, much of the active components including the ultraviolet absorbers would be lost in the process of removing the residues.
A great deal of research has gone into developing polish compositions that are free from abrasives yet do not streak or smear.
U.S. Pat. No. 5,700,312 discloses an auto finish-treating composition universally useful on paint, metal, vinyl and other plastic finishes comprising of micronized wax dispersed in a water/organic solvent emulsion also containing silicone liquid emulsified in both the organic and aqueous phases.
U.S. Pat. No. 5,882,387 discloses a wipe-on polish composition for automotive surfaces which contains no wax or abrasive components. The polish requires minimal effort to wipe out to a thin, glossy, streak-free, hydrophobic film. The polish is comprised of an emulsion that contains an organopolysiloxane and a volatile diluent.
U.S. Pat. No. 5,913,969 discloses a protective composition for automotive painted surfaces. The polish is comprised of emulsified silicone, an evaporation modifier and an agent, which increases wetting speed, dispersed in water.
Such micronized wax formulation and the polish formulations mentioned above lack durability and usually last for a few weeks only. Furthermore, since micronized wax or silicone oils are not film formers, UV protectants cannot be effectively incorporated in such products.
In view of these problems there is a need for a wax-based protectant that is substantially abrasives-free that does not smear or streak. Furthermore, UV protectants can be effectively incorporated in such a wax protectant to offer protection against sun damage.
It is one object of the present invention to provide a wax-based protectant composition, that is abrasive-free and therefore non-damaging to the clear coat type finishes, which provides protection to a substrate from sources of environmental damage. The sources of environmental damage can include for example, water, rain, acid rain, inorganic salts, dirt, grime, road tar, bird droppings and other environmental contaminants.
It is another object of the present invention to provide a composition that provides protection and screen from sunlight and UV rays to the substrate it is applied to. The UV absorbers and/or UV light stabilizers used in the present invention are hydrophobic in nature and are encapsulated in the wax particles.
It is another object of the present invention to provide a composition that leaves no residue. Therefore, substantial amounts of the wax, UV protectants, and other active components are left on the surface of the substrate. Furthermore, the protectant is very easy to apply since there is no buffing required and there are no powdery residues to remove.
It is another object of the present invention to provide a composition that can be applied to wet or dry surfaces and then wiped dry with no buffing, and provides a streak free, glossy finish. Furthermore, it can be applied to the wet surface to dry and wax the surface in one step.
It is another object of the present invention to provide a composition that can be applied to multiple surfaces such as automotive surfaces. Automotive surfaces include painted, plastic, chrome, glass, wood, veneer, and other surfaces of cars, motorcycles, trucks, boats, as well as other vehicles. Furthermore the present invention can be applied to other hard surfaces around the home and garage including furniture articles and glass surfaces.
It is another object of the present invention to provide a composition where the organic phase which may include wax, UV protectants, etc. has a specific gravity substantially close to that of the aqueous phase. This will substantially reduce the settling or separation of the organic phase from the aqueous phase.
It is another object of the present invention to provide a composition that is substantially free of solvents therefore it is environmentally friendly as well as consumer friendly.
It is another object of the present inv
