Engineering Solutions to Your HDD Challenges 

At our hard disk grinding and polishing R&D facility in Anaheim, California, Saint-Gobain materials scientists and engineers are perfecting coolants, cleaners and slurries for demanding surface conditioning applications ranging from aluminum disk grinding to glass media polishing. 

Our complete line of products for hard disk drive applications includes:

• Heat-treated mono and polycrystalline diamond slurries for slider bar lap
• Thermally treated monocrystalline diamond and polycrystalline diamond slurries for charging eutectic lapping plates (metal alloys such as Sn/Sb and Sn/Bi)
• Patented oil-based non-conductive lubricants for critical final lapping
• Ultra-pure cleaners for all in-process and post-process requirements
• Corrosion inhibitors to provide protection against the oxidation and corrosion of reactive metals such as cobalt, manganese, copper, nickel and iron
• CMP slurries for planarization and polishing of wafer devices and overcoat
