Saint-Gobain Surface Conditioning’s AmberCut 389W is a completely synthetic, water-soluble coolant formulated for use in high-tech applications. Recommended uses include cutting, slicing and grinding of ceramic materials as well as the general machining of many ferrous and non-ferrous metals. AmberCut 389W utilizes special lubricants that minimize chipping and improve surface finish.
AmberCut 389W contains a unique corrosion protection package that is effective on exotic metal alloys used in micro-electronic devices, such as PMR and advanced design read-write heads. It is specifically designed for coolant systems utilizing deionized water, where minimal substrate contamination is critical. Its unique formula contains very low levels of ionic contaminates, such as chloride and sulfate, making it excellent for use on sensitive micro-electronic devices.
AmberCut 389W is very low foaming and designed to minimize misting. It also contains a broad spectrum biocide, making it excellent for use in recycled coolant sumps. AmberCut 389W does not contain, sulfur, phosphorus, halogens, volatile solvents or formaldehyde-releasing materials.
