Paint spray booths used to spray large objects such as automobile bodies, appliances and the like employ acrylic finishes either in the form of aqueous emulsions or as oil-based coating compositions. It is customary to clean these surfaces of paint spray booths by spraying the surfaces which have become coated with the acrylic finishes due to overspray with aromatic solvent paint strippers. These solvents are usually such aromatic hydrocarbon liquids as xylene, toluene or mixed aromatic compounds derived from the refining of petroleum. These non-viscous solvents do not form a good adherent coating on the paint surfaces to which they are applied. To overcome this deficiency, it is customary to thicken these aromatic solvents.

Paint spray booths used to spray large objects such as automobile bodies, appliances and the like employ acrylic finishes either in the form of aqueous emulsions or as oil-based coating compositions. It is customary to clean these surfaces of paint spray booths by spraying the surfaces which have become coated with the acrylic finishes due to overspray with aromatic solvent paint strippers.

These solvents are usually such aromatic hydrocarbon liquids as xylene, toluene or mixed aromatic compounds derived from the refining of petroleum. These non-viscous solvents do not form a good adherent coating on the paint surfaces to which they are applied. To overcome this deficiency, it is customary to thicken these aromatic solvents. The present invention is directed to an improved thickened paint stripper for acrylic paints which adhere to the surfaces of paint spray booths.

The invention comprises a method of removing acrylic paints from the surfaces of paint spray booths which comprises the steps of. A Coating the painted surfaces of paint spray booths with a thickened aromatic solvent paint stripper consisting essentially of:. B Allowing the stripper to contact the paint for a period of time sufficient to cause it to be loosened from the surface; and then,.

These fumed silicas are used at dosages ranging between 0. This may be any aromatic hydrocarbon liquid as was described before, e. Both of these publications are incorporated herein by reference. Aromatic solvents are effective, low cost solvents for application in paint strippers. A major limitation to their use has been in effectively thickening this solvent type to provide the desired:. Fumed silicas, such as Aerosil , can effectively thicken an aromatic solvent to provide these desired characteristics.

Thickening occurs through formation of a silica network produced by hydrogen bonding of the silanol groups on the silica particle. The resulting thickened solvent is highly thixotropic which enables the product to be easily sprayed by reduction of viscosity through shear and then quickly recovers viscosity to provide good vertical clinging on the substrate.

Since the thickener is not polymeric, the material can be readily atomized for spray appliation. Also, a major advantage of the application of this thickener is that the formulated paint stripper can be easily rinsed off with water. Other thickeners that have been evaluated or used for thickening aromatic hydrocarbon solvents for application as a paint stripper include hydroxypropyl methyl celluloses, ethyl cellulose, aluminum octoate, polyisobutylene, polyvinyl pyrrolidone, and a borosilicatate.

In general, these thickeners either have required a high percentage of a more expensive co-solvent or did not provide the rheology and water rinsability vital in this application. Certain types of thickeners that would thicken the aromatic solvent such as the salts and high molecular weight, water insoluble polymers, were found to precipitate out onto the substrate when the paint stripper is rinsed with water to leave an unacceptable residue on the surface.

The high molecular weight, water-soluble thickeners required co-solvents which significantly raises the cost of the product. The compositions described above would be applied by spraying or any suitable means, most preferably spraying to the paint-contaminated surface of a spray booth.

They would be allowed to contact the hardened or tacky surface for a period of time to loosen and dissolve it and then would be removed by spraying the paint coated surfaces with water. Effective date : Year of fee payment : 4. Year of fee payment : 8. A method of removing acrylic paints from the surfaces of paint spray booths which comprises the steps of. B Allowing the stripper to contact the paint for a period of time sufficient to cause it to be dissolved from the surface; and then,. These compositions are useful in removing acrylic paints from paint spray booths.

The compositions described in the above process are thought to be novel in and of themselves. Dosage These fumed silicas are used at dosages ranging between 0. The Aromatic Solvent This may be any aromatic hydrocarbon liquid as was described before, e. The Preferred surfactants are non-ionic. A major limitation to their use has been in effectively thickening this solvent type to provide the desired: 1 viscosity, 2 thixotropy for clinging to vertical surfaces, 3 rheology for atomization in spray applications, and 4 water rinsability for removal.

A dissolving paint stripper of this type is known. It is applied to the dried paint coating and, after a short or long contact time, facilitates its removal from the substrate.

Ethers specifically mentioned include 1, 2-dime hoxyben- zene, 1, 3-dimethoxybenzene, 1, 4-dimethoxybenzene, 1,2,3- trimethoxybenzene, 2-methoxy-1, 3-dioxolane, 2-methoxy- 3 , 4-dihydropyran, 2 , 5-dimethoxytetrahydrofuran, ethylene glycol dimethylether, diethylene glycol dimethylether and i-t-butoxymethoxyethane.

These known paint strippers have the disadvantage that they are not sufficiently effective. In particular, they run down vertical paint surfaces before they have sufficiently softened them.

The solution provided by the invention is defined in the claims. The function of the thixotropic agent is to cause the stripper to form a low sag structure as quickly as possible after stirring. Thixotropic agents are well known in the paint industry and include, in particular, bentonites, kaolins, alginic acid and, above all, silica, for example fumed silica.

The function of the thickener is generally to increase the viscosity of the solution. Suitable thick- eners are inorganic thickeners, for example polysilicic acids and clay minerals, such as zeolites and silicas. Suitable organic modified natural substances may include carboxymethyl cellulose, cellulose ether, hydroxyethyl cellulose, hydroxypropyl cellulose methyl cellulose, ethoxyethyl cellulose and hydroxy propyl methyl cellulose.

Suitable organic natural thickeners are starch, gum arabic, dextrins, gelatine and alginates. The function of the surfactants is to improve wetting and washability. They may be anionic, cationic or nonionic. Alkylbenzenesulfonates in which the alkyl group contains 8 to 36 and more particularly 12 to 24 carbon atoms are particularly preferred. Waxes and vegetable ester derivatives in particular are used to retard evaporation. Organic acids and esters above all are used for activation.

Examples include formic acid, acetic acid and methyl phosphoric ester. The percentages by weight of the additives are based on the mixture of DMSO and co-solvent. The components of the paint stripper according to the invention may readily be mixed together. The paint stripper according to the invention has the following positive effects: low odor, complete solubility in water, - low evaporation rate and above all a long and favorable effect on virtually all paint systems and, finally, low health risk compared to dichloromethane based paint removers.

By virtue of its miscibility with water, the paint stripper according to the invention may readily be removed with water or with soap-containing water. The broad application spectrum of the paint stripper according to the invention despite its small number of solvents is surprising.

In a preferred embodiment, the paint stripper according to the invention contains only two solvents. Paints or varnishes based on the following organic binders may be removed with the stripper according to the invention: alkyd resin, chlorinated rubber, epoxy resin, acrylate resin, polyester, polyurethane, polyvinyl acetate, chlorinated polypropylene and cyclo rubber.
