SPECIALTY CHEMICALS AND ENGINEERED MATERIALS Glass Substrate and Media Cleaning Solutions Perform superior cleaning and protect glass substrates from undesirable etch Our hard disk drive (HDD) cleans are designed to be used after slurry polishing. They perform superior cleaning while pro- tecting glass substrates from undesirable etch. The formula- tion is designed to remove colloidal silica, ceria, slurry additives, suspension agents, organic residues, and inorganic sub-micron particulates left or embedded on glass disks during polishing. Our cleaning solutions significantly reduce surface ion contamination and remove, suspend, and completely disperse contaminants. Cleaners are formulated to be used at ambient temperatures and are exceptionally free- rinsing.
APPLICATIONS
Optics glass• Electronics glass• HDD glass• Post-CMP clean lines (immersion, brush, spray, ultrasonic, megasonic) FEATURES & BENEFITS High performance surfactant technology Allows high dispersion and free-rinsing Suspends and removes difficult-to-clean organic films, organic particulates, and inorganic particulates Reduces friction allowing easy use in brush processes Cleans effectively at ambient temperature Minimizes dry-down residues Well buffered cleaning solution Has high impact at a variety of concentrations (generally 1-10%)
