Product description:It is a polyvinyl butyral resin that is used as temporary binder for manufacturing metal powder granules.
Application:It is a fine-grained and free-flowing powder. Before processing, it has to be dissolved in specific solvents such as ethanol, butanol, etc. The solution is then mixed with metal powders and/or with diamonds for production of granules. The granules are thereafter submitted to cold pressing before sintering.
  • It is easy to use
  • It improves the green strength of cold pressed parts
  • It allows undamaged handling of the green parts until the furnace/hot press
  • It combusts at temperatures above 500°C, leaving no residues
