These are used in concentration ranges from a few ounces per gallon to very concentrated, depending on the type of work being processed. I am a chemical dealer suppling HF to aluminium utensil factories; they use diluted HF acid (20% to 30%) for dipping aluminum. As Ted said, it is widely used as an alternative to hydrofluoric acid, and I don't know whether there is or not some safer alternative. Ammonium bifluoride is sold in analytical grade for some uses, we use it to remove iron in chromate analysis (you make an error in excess by oxidizing iron if you don't add it). Our workers in the plant miscalculated and over-used a heavy-duty cleaner, so the aluminum parts got white residues after the cleaning process. The Prior Informed Consent Regulation administers the import and export of certain hazardous chemicals and places obligations on companies who wish to export these chemicals to non-EU countries. We are going into the nitric/ammonium post anodise for 25 seconds. [affil. If the substance is covered by more than one CLH entry (e.g. Please be aware there may be intermittent unavailability while work in ongoing. This substance has an industrial use resulting in manufacture of another substance (use of intermediates). The most prominent use is as a technical grade etchant in the ECHA has no public registered data on the routes by which this substance is most likely to be released to the environment. Substances for which classification and labelling data have been notified to ECHA by manufacturers or importers. The annexes to this directive provide detailed information about the minimum requirements for all safety and health signs. For example, copper does not dissolve in simple acids, but excesses of it must be removed from the surface of copper-bearing aluminum alloys before they can be anodized. This information is only displayed if the substance is well–defined, its identity is not claimed confidential and there is sufficient information available in ECHA’s databases for ECHA’s algorithms to generate a molecular structure. A. Hi again. ECHA has no public registered data on the routes by which this substance is most likely to be released to the environment. ECHA organises consultations to get feedback from all interested parties and to gather the widest possible range of scientific information for the regulatory processes. This substance has been found in the following regulatory activities (directly, or inheriting the regulatory context of a parent substance): This list represents a calculated inventory of substances based on the list of harmonized substances contained in Table 3 of Annex VI to the CLP Regulation (1272/2008/EC). disodium tetraborate EC no. 009-006-00-8 . 3.2, Table A), Directive 2008/68/EC, last amended by Regulation 2019/1243/EU, 25 July 2019, EU. I quickly found a reference which said a half million pounds was manufactured some years ago with projections of about a million by now; don't rely on my second-hand numbers though, find the sources of the data yourself. What is its context in cleaning steel-substrate? FORUMcurrent topics, A discussion started in 3.2, Table A), Directive 2008/68/EC, last amended by Regulation 2019/1243/EU, 25 July 2019, EU. Should I need a corrosion protection after the cleaning with ABF? This seems to work well but if need be can move towards the 16 ounces. note: now Accu-Labs, Inc. [a supporting advertiser]) to brighten the aluminum in our plating line. 3.2, Table A), Directive 2008/68/EC, last amended by Regulation 2019/1243/EU, 25 July 2019, EU. However, substance notifications in the InfoCard are aggregated independently of the impurities and additives. The Support section provides tools and practical guidance to companies which have responsibilities under the EU chemicals legislation. The CLP Regulation uses the UN Global Harmonised System (GHS) and European Union Specific Hazard Statements (EUH). InfoCards are generated automatically based on the data available at the time of generation. Substances for which an agreed set of classification and labelling data has been agreed at EU level by Member States. The Waste Framework Directive aims to protect the environment and human health from the generation and management of waste and to improve efficient use of resources. Hi Aakansha. Q. ---- Nitric acid is one of the few oxidizing acids and its oxidation power is required for some applications. Q. Also the use of an inhibitor are common and are optionally used to prevent over-etching and to avoid pitting. Table 3 of Annex VI to CLP Regulation); and (2) the Candidate List of substances of very high concern (SVHC). 2(b)(i) - Hazardous Agents, EU Ecolabels - Restrictions for Hazardous Substances/Mixtures, Workplace Signs - minimum requirements & signs on containers and pipes, Waste Framework Directive, Annex III - Waste - Hazardous Properties, Fertiliser Regulation- Annex I, E.3 (chelating and complexing agents), C&L Inventory, Pre-Registration process, Other, Inland Transport of Dangerous Goods Directive, Annex I - ADR, Inland Transport of Dangerous Goods Directive, Annex II - RID, CAD - Chemical Agents Directive, Art. Are there other more suitable baths? A. Substances may have impurities and additives that lead to different classifications. REACH registration dossiers have greater data requirements (such as supporting studies) than do notifications under CLP. Deleted CAS number. Good day Nigel. This list contains substances whose use in cosmetic products in the EU is banned except under certain conditions as indicated in the annex. Would you please give me some advice about the ABF? Q. Dangerous Goods List (ADN, Chap. It is the responsibility of the substance manufacturers and importers to consult official publications, e.g. While the harmonized list covers many hazardous substances, other ones not listed may also meet the classification criteria in accordance with the CLP. On passing hydrogen fluoride gas (in excess) through the salt, ammonium fluoride absorbs the gas to form the addition compound ammonium bifluoride. What is the Classification and Labelling Inventory? } This list contains biological and chemical agents, in accordance with Art. Identification Product Name Ammonium fluoride Cat No. Non-Exhaustive List of Banned Substances, Directive 94/33/EC on Young People at Work, 20 August 1994, as amended by Dir 2014/27/EU, March 5, 2014 (Based on Table 3 of Annex VI to CLP, inter alia), EU. "text": "#237afc" (Sorry, my question is for ABF, Ammonium bi-fluoride, not chloride. SAFETY DATA SHEET Creation Date 16-Nov-2010 Revision Date 17-Jan-2018 Revision Number 3 1. Thanks. Regards Hi Asim. I want to know how much % age ABF should be mixed in HF acid for better shining of aluminium. Likewise the per substance indication of harmonised C&L, Seveso directive, or notified C&L regulatory context will be made available as soon as possible. "button": { Is one safer? Regards Thanks for your feedback on this. info Hi SK, Q. Hi Mr.Ted Mooney, Occupational exposure limit (OEL) values are derived within two legal frameworks that form an integral part of the EU’s mechanism for protecting the health of workers. Q. Hi. C&L Inventory . elements_selector: "iframe" BPR regulation aims to improve the functioning of the biocidal products market in the EU, while ensuring a high level of protection for humans and the environment. Release to the environment of this substance can occur from industrial use: formulation of mixtures. A. Hello, C. We are probably misunderstanding you. We use nitric acid solutions ranging around 50% with anywhere from 1% to 10% ammonium bifluoride as a de-oxidizer/etchant.
