ICS-400

ICS-400 is a high purity gypsum bonded investment containing non mineralized cristobalite and special additives.

ICS-400 offers a superior combination of quality and value in an investment for professional casters.

ICS-400 is recommended for high volume Jewelry Casting Manufacturers using gold, silver and other nonferrous alloys because of the following qualities:

• Smooth as cast surface finish - due to the fine mesh of ICS-400 and through careful formulation the surface finish obtained with ICS-400 is superior.
  
  
• Low rise under vacuum - ICS-400 contains special additives to control the rise or boiling action of the investment when placed under vacuum. These additives also improve the wetting of wax patterns helping to eliminate air bubbles.
  
  
• Quality consistency and value - every batch of ICS-400 is tested for physical and chemical properties before shipping. Only the highest purity raw materials are used to manufacture ICS-400. ICS-400 is reasonably priced compared to other investments made with the same quality raw materials.
