This is particularly desirable when the formulation is to be applied by brush, roller or spray. The use of a paint remover formulation according to any preceding claim as a paint remover. The paint remover formulation may include additives, such as thickeners and surfactants. 13. A paint remover formulation comprises a mixture of aqueous hydrogen peroxide solution and a paint removal accelerator. C12 to C14 alkyldimethylamine oxide 3.1 wt%, Amorphous silica 5.0 wt% Sodium diethylenetriaminepentaacetate 0.2 wt%, Hydrous sodium lithium magnesium 1.5 wt% silicate, Sodium diethylenetriaminepentaacetate 0.2 wt%. Looking for BACK TO NATURE Paint Remover, 1 gal., Benzyl Alcohol Base (499H60)? The presence of the surfactant and the thickening agent make it possible to add the accelerator to the rest of the formulation some time after it has been formed. This is made by mixing benzyl alcohol with formic acid, the alcohol then reacting in situ with the formic acid to provide the benzyl formate. Grainger's got your back. Sign In to access your account information. Price $97.50. Based on benzyl alcohol and hydrogen peroxide, these strippers are based on Selective Adhesive Removal Agent (SARA) technology. It is commercially available in aqueous solutions containing up to about 60 wt% hydrogen peroxide, but this concentration can be very hazardous. The resultant gel was then added to a mixture of the other ingredients, with stirring. EP-B-0497130 describes a paint remover formulation containing benzyl formate, benzyl alcohol and formic acid. The accelerator may be supplied separately from the other ingredients, so that the two can be mixed shortly before application to paint. The formulation may also include a corrosion inhibitor. A1, Designated state(s): diethylenetriaminepentaacetatθ. We have found that the combination of hydrogen peroxide, with one or more of the accelerators specified above, provides paint removal that is more effective than using hydrogen peroxide alone, or using the accelerator alone. 14. The accelerator is immiscible with the hydrogen peroxide solution, and the surfactant serves the primary function of assisting the formation of a stable emulsion of the accelerator with the hydrogen peroxide solution. 7. This item is restricted for international sale. Benzyl alcohol paint removers are authorized for use in T.O. In particular, the formulation has a very pungent smell, because of the presence of formic acid. The thickening agent may be organic or inorganic. The amount of hydrogen peroxide in the formulation should be as high as possible. StripIt GOLD Paint Remover 12/19/19 Page 5 of 5 Benzyl Alcohol: 96h LC50 Pimephales promelas 460 mg/L; 48h EC50 Daphnia magna 230 mg/L; 72 hr EC50 Pseudokirchnerella subcapitata 770 mg/L Monoethanolamine: 96 hr LC50 Cyprinus carpio 349 mg/L; 48h EC50 Daphnia magna 65 mg/L; 72 hr EC50 Pseudokirchnerella subcapitata 2.5 mg/L We have now devised an improved paint remover formulation which is very effective in use, which is less acidic and less odorous than the formulations described in EP-B-0497130, and which is more stable than the formulations described in US-A-3355385. A paint remover formulation according to any preceding claim, comprising between 0.7 and 3.0 times as much hydrogen peroxide, by weight, as accelerator. Easy online ordering for the ones … A paint remover formulation was prepared by mixing together the following components in the amounts specified. This can help to improve the shelf life of the formulation, because accelerator may degrade after several months storage, particularly in hot climates. This is particularly a problem when a large amount of the paint remover is used in a confined space, as can occur, for example, when the formulation is used to strip paint from aircraft in hangars. Our preferred paint removal accelerator is benzyl alcohol, with which we have achieved the best results. 2. In practice, it would be difficult to use more than 60 wt% hydrogen peroxide in the formulation, due to the difficulty of obtaining supplies. In general, the greater the stability of this emulsion, the longer the shelf-life of the formulation. Additives could be added to the hydrogen peroxide in order to try to improve the effectiveness, but it is difficult to find additives that are stable when mixed with it. In order that the invention may be more thoroughly understood, the following examples are given by way of example only. Traditionally, paint remover formulations have been based on chlorinated solvents such as methylene chloride. It is desirable that the formulation according to the invention contains a sequestrant for iron. 8. As mentioned above, it is sometime preferable to blend in the accelerator after blending the other ingredients. When the thickening agent is an inorganic thickening agent, then it is preferably present in an amount from 1 to 10 wt%, more preferably 1.5 to 7 wt%. The sequestrant is suitably sodium Access My Account, Order History, Lists and more here. The formulation may also include mineral oil to retard evaporation. In the following description we use the expression "benzyl alcohol" to include the functional derivatives. reduce the effectiveness of the paint removal. The amount of hydrogen peroxide specified above relates to the amount pure hydrogen peroxide, not to the amount of the aqueous solution. 1-1-8 and a list of approved products is provided. A paint remover formulation according to claim 1 , comprising the following composition: 17. High concentrations are usually impractical, but lower concentrations 11. CARC Removal. A paint remover formulation according to any preceding claim, further comprising a surfactant.
