Chrome-synthetic retanning agent.
SINTOCROM GD is a retanning agent based on basified chrome salts and complexing and neutralizing synthetic agents in liquid form. It is not therefore a simple blend but a real chrome complex.
The chrome content is about 6.5% (express in Cr2O3).
SINTOCROM GD is a pre-tanning and retanning agent that is suitable for all types of articles. The synthetic component confers to the leather a good fullness, good softness and a fine grain, leaving anyway the typical character of the chrome tanning.
The dyeability of the leathers treated with SINTOCROM GD is excellent: we obtain a uniform dyeing with a full and clear shade.
Thanks to its high light fastness, SINTOCROM GD is also suitable for the production of white leathers.
The recommended amount to be used vary from 3% to 5% according to the structure of the skins and the required article.
