Pretreatment for Plastic Metallization

  • Sulfonation has been proposed as an alternative to conventional etchants in the preparation of a variety of resins for the purpose of surface activation via electroless plating chemistries and ultimately chrome plating.
  • Trials with traditional materials like ABS and PC/ABS have shown great promise with several process profiles yielding adhesion levels comparable or superior to chrome VI based etchant.
  • Sulfonation has the unique capability to be effective over a broad spectrum of organic resins (poly amides, TPO, HDPE, etc.) as apposed to traditional methodologies that require multiple steps to accommodate different resins
  • Sulfo Technologies has partnered with plating on plastic chemical suppliers and plating contractors to continue the development of this technology
