摘要

Chemtan E-68 is a modified phenolic syntan with extremely low free formaldehyde and phenol levels. It is suitable for use in sport shoe and automotive leathers with low formaldehyde content requirements. Chemtan E-68 has excellent lightfastncss and provides a high level of filling, softening and bleaching. Leather dyeings are more level when Chemtan E-68 is used. When used in neutralisation Chemtan E-68 increases grain filling and tightening. Applying Chemtan E-68 in the retan will result in further filling and improved dye levelness and penetration. It can also improve the penetration of extracts and resins thus preventing the grain from being overloaded.
