|  | KC-Trockenperlen WS+Water-resistant adsorbent
 
 Water-resistant  adsorbent, also known as KC-Trockenperlen  WS+ BASF SorbeadWS+ water-resistant silica gel adsorbents have high capacity and protect other adsorbents and catalysts from water and moisture in a broad  range of  applications.
 The patented  BASF Sorbead line of highly efficient  adsorbents are alumino-silicate gels in the form of hard, spherical beads, with a very high resistance to crushing and a low attrition rate. Sorbead adsorbents have a longer life than most other adsorbents and can reduce operating costs in most applications.
 Sorbead WS and  WS+ are the only 100% water-resistant  adsorbents with a high adsorption capacity.  Sorbead WS+ is especially developed  for operations requiring special product  features like low corrosion risk or  high crush strength and is most frequently  used as a 20% protective layer against  condensed water in combination with  Sorbead H or Sorbead R+.
