Solutions for tanning and retanning

Ventan RCS

PRODUCT NAME	APPLICATION
Re-chromingsyntan	Appearance: Green coloured free flowing powder % Moisture content: 5.0 max.Ionic charge. Anionic Solubility in Water: Readily soluble Stability to electrolytes: Very good pH of 10% solution: 3 ± 0.5 — In re-chroming it helps in maintaining chrome character of the leather with good fullness & softness.Re-chroming with Ventan RCS gives leathers a tight and fine grain.It increases the affinity of leather for dyestuffs and ensures level dyeing.It exhausts completely from re-chroming bath at elevated temperature. Due to its masked chrome complex nature, when used as pre-tanning agent, rapid penetration of pelt takes place and this facilitates acceleration of subsequent vegetable tanning process. — In general, 2 -4% (on shaved wt.) is applied priorto neutralizing.For pre-tanning, 1-2% (on pelt wt.) is applied after the pickle in the same bath.For chroming wet white leathers, 2-6% (on pelt wt.) is applied in combination with other tanning agents. — Product is stable for one year from date of manufacture, if stored at ambienttemperature in supplied packing.

Frequently Asked Questions - Powder Syntans

Find answers to common questions about powder syntans

What are powder syntans?

Powder syntans are synthetic tanning agents in powder form used for retanning, pre-tanning, and neutralizing operations in leather processing. They include phenolic syntans, acrylic syntans, resin syntans, and neutralizing syntans that improve leather quality and processing efficiency.

What types of powder syntans does Esteem Industries offer?

We offer various powder syntans including VENTAN RCS (re-chroming syntan), VENTAN DPS (dye leveling syntan), VENTAN PTS (phenolic pre-tanning agent), VENTAN RPS (phenolic replacement syntan), VENTAN WRS (white leather syntan), VENTAN AMS (amphoteric syntan), VENTAN MRS (melamine resin syntan), and VENTAN PNS (phenolic neutralizing syntan).

What are the advantages of powder syntans?

Powder syntans offer easy storage and handling, good solubility in water, excellent filling properties, improved leather fullness and softness, enhanced grain tightness, good light fastness, compatibility with other tanning agents, and cost-effective processing.

How are powder syntans used in leather processing?

Powder syntans are used for retanning chrome leathers (applied after neutralization), pre-tanning operations (to accelerate vegetable tanning), re-chroming operations (to maintain chrome character), neutralizing operations (to adjust pH safely), and as replacement agents for vegetable tannins in various leather types.
