TFL launches liquid astringent tanning agent

27/01/2015
Chemical-maker TFL has launched a liquid astringent tanning agent which will help tanners deal with “challenging raw material quality” and produce tight and compact leather articles, it says. 

As retanning agent for both chrome and chrome-free leathers, ‘SELLATAN HAT liq’ can help produce fullness with a tight, uniform grain break for shoes, handbags and automotive leathers. 

TFL says concentrated syntans that normally come in powder form can making automatic dosing difficult and significantly contribute to the salt in wastewater. However, SELLATAN HAT liq can replace powder syntans one to one.

“The product contributes very little to the formaldehyde content in the final leather,” said the German company. “The low formaldehyde and phenol content and the minimal TDS contribution make it ideal for TFL White Line Technology.”
