    Price Term: FOB 
    Package:  25kg/pcs


    Quartz Glass Frosting Powder ST-102 is specially made for highly-pure silicon-dioxide-quartz glass , such as: Quartz Halogen, tungsten lamps etc. ST-102 Quartz Glass Etching Powder, based on industrial grade Hydrochloric Acid, can be used at indoor temperature. The Quartz Halogen lamps frosted by ST-102 are white and soft. 

    Frosting Operation >> Preparation of the Frosting Solution     
    * Mature the frosting solution at least 24 hours before use
    * The ratio of powder ST-102 to Hydrochloric Acid (≥31) is 1:0.30 
    * Keep the powder in a plastic container, slowly pour Hydrochloric Acid in, and keep stirring 
       the solution evenly. Finally, cover the container.
    * Keep maturation over 24 hours before use (The longer, the better)
    * The newly-prepared solution is too thick, and its temperature will fall down slowly, 
       so don’t apply it until it comes back to be normal in temperature and thickness. 

    Frosting Operation >>Frosting Process
    * Dip the clean Quartz glass into the solution and constantly stir it
    * Take out the frosted glass to dry it
    * The frosting time varies with single-layer or double layer etching. It varies between 
       5 and 10 minutes
    * A second frosting can help the glass appears more white.
      
    Frosting Operation >>Wash & Dry Process 
    * Rinse and wash the frosted glass under the running water or dip the glass into the
      5-10 diluted Hydrochloric Acid for 20-60 seconds to make abrasive particles on the 
       glass easy to remove
    * Rinse and wash the glass again under the running water and dry it with air.
