This group of paint removing chemicals was introduced to address the disadvantages and health hazards of existing paint stripping chemicals available. It’s chemical is safe and doesn’t react with skin and release harsh fumes. The principle of paint strippers is penetration of the paint film by the molecules of the active ingredient, causing it to swell; this volume increase causes internal strains, which, together with the weakening of the layer's adhesion to the underlying surface, leads to separation of the layer of the paint from the substrate. The activator's role is to disrupt the molecular and intermolecular bonds in the paint film and assist with weakening this. Unique, cost effective, reusable formula for the removal of multiple layers of finish, varnish, stains, latex paint and oil paint, as well as log exteriors and interiors and on fine furniture and cabinets. Pro Coating Remover can be used to strip paint from wood, metal, brick, fibreglass and stone. Some types of methylene chloride paint strippers are flammable, while others are not. Caustic paint removers, typically sodium hydroxide (also known as lye or caustic soda), work by breaking down the chemical bonds of the paint, usually by hydrolysis of the chain bonds of the polymers forming the paint. Caustic removers must be neutralized or the new finish will fail prematurely. Mineral acids are used for epoxy resins to hydrolyze their ether bonds. This least expensive paint removing mixture should be avoided in closed spaces or those with poor ventilation. Paint stripper, or paint remover, is a chemical product designed to remove paint, finishes, and coatings while also cleaning the underlying surface. Lead-based paint is banned in the United States. Extreme caution should be used when using paint strippers containing this ingredient. Although numerous chemicals and paint removal agents are available in hardware stores, "paint strippers" or chemicals that are used to remove paint fall under two main categories: SBS or solvent-based strippers and CBS or caustic-based strippers. AUSTRIP 6689 . Extreme caution should be used when using paint strippers containing this ingredient. It has orange like smells and very easy to apply as compared to other chemical based paint strippers. It effectively delaminates layers of paint instead of liquefying them, as other chemicals typically do. They effectively remove a wide range of paint coatings, including older (calcimine paints and milk) and newer finishes. Paint can also be removed using mechanical methods (scraping or sanding) or heat (hot air, radiant heat, or steam). These chemicals work well to remove newer paint, but are not as effective against the older coatings. EPA proposed a ban on methylene chloride in paint and coating removal products during the final days of the Obama administration in early 2017. Friday 27 May 2005 1:00:00 am. Their main drawback is their flammability, making their use a potential hazard. They cannot be used to remove paint from galvanized steel, magnesium stainless or aluminum. Toluenelmethanol chemicals are used scarcely and only in controlled environments. AUSTRIP 6689. This chemical, also known as dichloromethane or DCM, is the active ingredient in many chemical paint strippers. ALKOGEL HIKLEAN . It can also be used to remove graffiti. Methylene chloride-based paint removal agents are available in gel and liquid form, with the gel version used as the primary paint removal and the liquid as the final wash. Corrosion inhibitors are added to the formula to protect the underlying substrate and the paint stripper storage vessel (usually a steel can) from corrosion. Surfactants assist with wetting the surface, increasing the area of where the solvent can penetrate the paint layer. This "slow-working" extended-contact remover, remains active for 24 hours. – and can also be used on a wide variety of paints and coatings, including lacquers, varnishes, stains and powder coatings. Ethanol is suitable for shellac, methyl ethyl ketone is used for cellulose nitrate, and phenol and cresols are employed in some industrial formulas. Such caustic aqueous solutions are typically used by antique dealers who aim to restore old furniture by stripping off worn varnishes, for example. Just brush on thin layer and wait for an hour to get chemical dry and react with paint. Paint stripper, or paint remover, is a chemical product designed to remove paint, finishes, and coatings while also cleaning the underlying surface. The product's material safety data sheet provides more safety information than its product labels. Gel formula for vertical surfaces (thixotropic) Diggers Paint Stripper Domestic Formulation is a low odour, biodegradable, Methylene Chloride free alternative that deeply penetrates and quickly lifts paint for easy removal. Considered environmentally friendly and non-toxic, these paint removers take anywhere from 12 to 42 hours to work. Some cosolvents double as activators. Various co-solvents are added to the primary active ingredient. The formula differs according to the type of paint and the character of the underlying surface.  Fire is a possible hazard of using heat guns. Dichloromethane has serious health risks including death,  is likely a carcinogen, and is banned in some countries for consumer use.. Sure KIean ® Heavy Duty Paint Stripper, an alkaline formula with organic solvents, removes multiple layers of paint and graffiti from masonry surfaces. Solvent paint strippers penetrate the layers of paint and break the bond between the paint and the object by swelling the paint. Due to its formula, this paint remover is suitable to strip multiple layers of paint – up to 20! Alkaline based gelled stripper. Anionic surfactants (e.g., dodecyl benzenesulfonate or sodium xylene sulfonate) are used for acidic formulas, cationic or non-ionic are suitable for alkaline formulas. Citri Strip paint is the best chemical based paint remover. Amine activators, alkalines weaker than inorganic hydroxides, are favored when the substrate could be corroded by strong acids or bases. Heat guns are an alternative to chemical paint strippers. One application of Heavy Duty Paint Stripper dissolves heavy accumulations of paint, restoring old masonry to its original appearance. This at home solution is just as strong as anything you could buy at the store and just as toxic. High-temperature heat guns at 1,100 °F (590 °C) or more create toxic lead fumes in lead-based paint, but low-temperature heat guns and 400 °F (200 °C) infrared paint removers do not create lead fumes.
