Product Description S-U-LPHAMIC ACIDTechnical gradeDescaler, Cleaner, Rust & Limescale RemoverS-ulphamic acid also called s-ulfamic acid is a white crystalline solid which is stable and non-hygroscopic. It is soluble in water and formamide and slightly soluble in m-e-thanol, ether, a-c-etone and concentrated s-ulphuric acid. It is classified as a strong inorganic acid and is commercially produced from urea and fuming s-ulphuric acid. At room temperature, dilute aqueous s-ulphamic acid solution is stable for a long time but rapid hydrolysis occurs at elevated temperatures. It's solution is less corrosive toward metals than other mineral acids like h-y-drochloric acid. S-ulfamic acid possesses a scale solubilising capacity which makes it ideal for removal of scale from boilers, cooling towers, coils, heat exchangers, condensers and a wide range of heating and cooling systems thereby increasing the efficiency of plant and equipment.S-ulphamic acid is used as an acidic cleaning agent, typically for metals and ceramics. It is a replacement for h-y-d-rochloric acid for the removal of rust. In households, it is often found as a descaling agent in detergents, cleaners and toilet cleaners for the removal of limescale.Properties of S-ulphamic acidSynonymsS-ulfamic Acid; Amidosulfonic acid; Amidosulphonic acid; sulphamidic acid;CAS NO5329-14-6EINECS NO226-218-8Molecular formulaNH2S03HPurity99.5%minAppearanceWhite CrystallineApplicationHerbicide,fireproof agent, softener, metal cleaning agentMolar mass97.09 g/molDensity2.15g/cm3Solubility in water213 g/L (20C)Melting point190 - 225 CBoiling pointdecomposesPH1.2 (1% solution @ 20C)USES OF S-ULPHAMIC ACID:Descaler, Cleaner & Rust Removerremoving excess grout on tiles, efflorescence and other mineral depositsCleaner & descaler for Dairy equipment (pipeline milkers, milk evaporators)Cleaner & descaler for Brewery equipment (pipelines, Vats, etc)Catalyst for esterfication process processUsed in dye and pigment manufactureUsed as a herbicideEffective against Foot and Mouth (approved by Defra)Ingredient in Denture TabletsCoagulator for urea-formaldehyde resinsIngredient in fire extinguishing mediaPulp and paper industry as a chloride stabilizerSynthesis of n-i-trous oxide by reaction with n-i-tric acidPackaging, Storage and Transportation25kg PP/PE bag;27 tons per 1x20'fcl with pallet. Storage and transportation should be kept in a cool, dry place and avoid exposure to high temperatures; during transportation, the packaging should be intact, waterproof, and moisture-proof.S-ulphamic acid in descalingS-ulfamic Acid is super efficient descaling agent and is used for cleaning a variety of industrial equipment and domestic appliances. It is used for cleaning boilers, heat exchangers, condensers, jackets and coils, descaling toilets, removing excess grout on tiles, efflorescence and other mineral deposits etc (See below for details on how to use). It helps remove hard water scale, protein deposits, beer and milk stone, light rust and copper corrosionS-ulphamic acid in paper & pulp IndustryS-ulphamic Acid prevents pulp degradation due to temperature at the chlorination and hydrochloride stage. It permits bleaching at higher temperature and lower pH without loss of strength.S-ulphamic acid is used in manufacturing of Dyes, Pigments and in the dyeing of leatherS-ulfamic Acid removes excess of nitrides used in the diazotization reactions in the manufacturing of dye stuffs and pigments. Nitrides if present in process water of effluents can also be removed by using S-ulphamic AcidS-ulphamic acid in C-h-lorine StabilizationS-ulphamic Acid is used for stabilizing c-h-lorine in swimming pools and cooling towers.S-ulphamic acid in Electroplating and Electro-refiningS-ulphamic acid in Sulphation and SulphamationS-ulfamic acid is used for sulphation and sulphamation of many organic compounds.How to use S-u-lphamic Acid for cleaning & descaling:For removing excess grout from tiling or dissolving efflorescence from walls, floors etc: Make up a solution of s-u-lphamic acid by dissolving 80-100g per litre of warm water. Apply to surface using a cloth or brush and allow to work for a few minutes. Agitate with brush if necessary and rinse with clean water. Please Note: if using around coloured grout use a weaker solution of approx 2% (20g per litre of water) to reduce the risk of leaching out any colour from the grout.For descaling equipment use a 10% solution. S-u-lphamic acid is safe for steel, iron, glass and wood equipment, and may be used with caution on copper, aluminium, and galvanized metal surfaces. Clean in a soak tank or by circulation. For surfaces, apply to surface using a cloth or brush and allow to work for a few minutes. Agitate with brush if necessary and rinse thoroughly with clean water.For Boiler systems & Cooling Towers use a circulation treatment of a 10% to 15% solution depending on how bad the system is. Before applying flush out system and refill with clean water. Determine the volume of water and mix in the s-u-lphamic acid at a rate of 100g to 150g per litre of water. It may be necessary to add a corrosion inhibitor to help protect mild steel, brass, copper and stainless steel from acid attack. Circulate the solution at room temperature or heated to a maximum of 60C for heavier cleaning for several hours until desired results are achieved. Note: Do not use at boiling point or product will undergo hydrolysis and will not work. Do not use on galvanised materials, zinc or aluminium. S-u-lphamic acid will not remove silica or calcium phosphate scales. After cleaning rinse thoroughly and check system. Neutralise with 1 to 2% sodium carbonate solution (soda ash) with a target pH of 6 to 8 or whatever discharge pH range applies.Repeat applications may be necessary for heavily soiled systems. After cleaning Periodic flushing of the system to remove loosened scale and contaminants will be necessary.For rust removal use a solution of 10%-20%.Health & SafetyR-phrase(s): R36/38 Irritating to eyes and skin. R52/53 Harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment.S-phrase(s): S26 In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. S28 After contact with skin, wash immediately with plenty of soap and water. S61 Avoid release to the environment. Refer to special instructions/ Safety data sheets.
