Sprint/Nextel Record Alum Hardening Converter Additive 1Ltr

Sprint Record Alum Hardening Converter 1Ltr

Sprint Record Alum Hardening Converter is a professional-grade fixer additive supplied in a one-litre bottle. It toughens photographic emulsions on black-and-white films and papers, increasing resistance to abrasion and water absorption. The formulation enhances archival permanence when used correctly. Darkroom workers handling resin-coated or fibre-based media will find it essential for durable results.

Behaviour under sustained darkroom use

The additive hardens emulsions consistently across extended processing sessions, maintaining protection against scratching during repeated wet handling. It promotes a hard gloss on glossy resin-coated prints and stabilises fibre-based sheets destined for hot-drum drying. Correct timing and thorough washing prevent excess hardening that could compromise image quality. Performance remains reliable throughout the working life of the fixer bath.

Replaces standard non-hardening fixer workflows

Photographers moving from basic fixer-only routines gain abrasion resistance and archival stability for both film and print emulsions. The jump is worth it when resin-coated prints must survive frequent handling or when fibre-based work requires hot-drum drying. It is not for users who process only colour materials or who rely on pre-hardened emulsions that need no additional treatment.
