It is also suitable for any application requiring effective gelatin hardening, including the carbon transfer process and other gelatin-based photographic techniques.

Applications:

• Gum bichromate printing
• Carbon transfer printing
• Gelatin hardening and tanning
• Preparation of papers for alternative photographic processes
