REPLACEMENT SYNTANS -
Replacement syntans are leather chemicals used as synthetic substitutes of vegetable tanning agents for retanning of chrome tanned wet blue leather or E.I. tanned leathers.
Replacement syntans are based on the condensation products of phenol and naphthalene sulfonic acids.
- Replacement syntans are favoured for retanning chrome leather to improve fullness and level dyeing thru uniform uptake and penetration of fatliquors and dyes which leads to improvement in buffing properties.
- Replacement syntans reduce cationic charge of chrome leather.
- Replacement syntans are used to produce white leathers.
- Replacement syntans are also amphoteric with respect to their ionic charge and these can be used at different pH conditions exhibiting pH dependant tanning properties.
Ventan RPS is replacement syntan suitable for all stages of tannage for production of all kinds of leather. It is available in the form of spray dried free flowing powder.
Ventan WRS is replacement syntan suitable for producing white leather from chrome tanned leather. Ventan WRS can also be referred to as bleaching syntan or white syntan. It is available in the form of spray dried free flowing powder.
