Sprint Record Alum Hardening Converter, Additive 1Ltr

Because unhardened emulsions can be easily scratched when wet and tend to absorb moisture when dry, our high-quality Record Alum Hardening Converter and Fixer Additive is the perfect solution for black and white films and papers. This professional-grade product is designed to toughen emulsions, making them more resistant to abrasion and water absorption. When used correctly, it significantly enhances archival permanence by providing robust protection to emulsions.This effective fixer additive is a must-have for all black and white films, as they require alum hardening in the fixer. It's also essential for resin-coated prints, where it prevents scratching and promotes a hard gloss on glossy finish papers. For fiber-based prints, our durable and easy-to-use Record Alum Hardening Converter and Fixer Additive should be used under specific circumstances, such as when prints are to be dried on hot drums or if the emulsion is very soft. While fiber prints are hardened during manufacture, and by heat, light, and air, additional hardening using our product can enhance their quality, provided it's correctly timed and well-washed. However, it's important to note that excess hardening can make prints brittle, curly, and difficult to wash and tone archivally. To ensure thorough washing and even toning, treatment with ARCHIVE Fixer Remover is recommended.
