  • What are anti-oxidants used for?
  • Anti-oxidants are used to prevent skin formation in air-drying coating systems that contain driers as accelerators. These are usually organic compounds that inhibit or delay the undesirable oxidative processes caused by the influence of oxygen during storage.
  • Are phenolic anti-oxidants good for skinning?
  • A typical feature of phenolic anti-oxidants is that, being genuine oxygen inhibitors, they have very good anti- skinning effects. However, due to their generally low vapor pressure, they a l s o have low volatility and, therefore, may delay the drying of a coating to an undesirable extent.
  • Are phenolic anti-oxidants sterically hindered?
  • Sterically hindered phenolics can, in addition to transferring a hydrogen atom, also bind the resultant peroxy radicals R – OO• . A typical feature of phenolic anti-oxidants is that, being genuine oxygen inhibitors, they have very good anti- skinning effects.
  • How are anti-oxidants produced?
  • Highly effective anti-oxidants can be produced by combining a radical interceptor with a metal complexing agent. However, the anti-oxidative effect can also be improved by further measures, such as additional combination with UV stabilizers. Borchi® and Ascinin® are registered trademarks of Borchers GmbH, Langenfeld, Germany.
  • What are stabilizers & antioxidants used for?
  • Stabilizers (Antioxidants) can be used to delay the aging process. Some of the technical fields of application for Antioxidants and the processes they prevent are: Oils and binders that undergo oxidative crosslinking by reaction with oxygen, and as a result form a solid polymer film, may undergo surface skin formation during storage.
