Italian leather chemicals manufacturer Silvateam will have an innovative hybrid tannage idea on display at the India International Leather Fair in Chennai, February 1-3.
The new system uses a combination of chrome salts and Blancotan CAT, a new syntan based on dihydroxydiphenyl, a sulphone condensation product with cationic charge.
Blancotan CAT can be used alone on pickled hides as a pretanning agent to produce a wide range of chrome-free leather articles with what Silvateam describes as “a user-friendly process”. Alternatively it can be used with conventional chromium salts in any proportion to obtain low-chrome tannages with high exhaustion floats.
