Auxiliary photographic chemical used as a hardener in fixers and stop baths. Strengthens the gelatin emulsion of films and photographic papers, shortens washing times and reduces water consumption. Especially suitable for baryta papers and black & white films.
TETENAL Hardener Liquid is an auxiliary photographic chemical designed for use in fixers and stop baths during black & white film and photographic paper processing in the darkroom.
The hardener strengthens the gelatin emulsion, increasing its mechanical resistance during processing, especially at higher temperatures or when working with softer emulsions. At the same time, it acts as a wash aid, helping to remove residual chemicals more efficiently, shortening washing times and reducing water consumption.
It is particularly suitable for baryta photographic papers, but can also be used with black & white films.
