Formic Acid 85% — Leather & Rubber Industry, India

Formic acid (HCOOH, CAS 64-18-6) is a pungent, corrosive organic acid Drashti Chemicals stocks from Vadodara for leather deliming assists, rubber latex coagulation, textile dyeing auxiliaries, silage preservation blends and industrial cleaning formulations across Gujarat. Buyers usually request 85% industrial liquid with assay on the COA; strength and iron content should be checked before charging a bath.

We are a Vadsar stockist/supplier, not a formic acid plant. The acid is both a proton donor and a mild reducing agent — recipes that assume acetic behaviour may fail if swapped without tannery or dye-house approval. Food-adjacent preservative grades need explicit naming on the RFQ; industrial 85% is not assumed food-ready.

Leather plants dose into deliming and pickling loops per SOP; rubber units coagulate latex with controlled addition. Vapour is irritating — local exhaust and face protection are expected. Store in HDPE or lined steel with bunding; dilute by adding acid to water. Never mix blindly with strong oxidisers or chromic systems.

Packing runs HDPE carboys and drums for standing POs; bulk tanker paths can be quoted for larger chemical zones. Batch COA and MSDS travel with every lot. Dispatch from Vadodara toward Kanpur leather corridors, Surat textile belts and local GIDCs on hazmat-aware carriers.
