Introduction

We are Dyechem

By keeping R&D in-house, we make sure our clients stay ahead of every regulation — and every trend.

A surface chemistry company built for the next fifty years of manufacturing. Since 1975 we've gone from distribution to manufacturing to full in-house R&D — engineering water-based metallic coatings and finishes for textile, leather, jute, paper, and glass.
We believe sustainable chemistry is not a compromise. Everything we supply is water-based, ZDHC compliant, and free of VOCs and microplastics — and our in-house formulations go further still: biodegradable systems engineered to outperform the solvent chemistry they replace, not just substitute it.
Our network spans six branches from Kolkata to Dhaka, with exports worldwide. Three generations of one family have run this business since 1975, and the same standards run through everything we formulate, test, and ship.

Our vision is to pioneer chemistry that is sustainable by design — not by afterthought.
We're not just supplying coatings — we transform substrates. Whatever the surface, we're setting the cleaner, smarter standard for finishing it.

Say goodbye to solvent-based, legacy chemistry.

We've rebuilt metallic finishing from the ground up — replacing solvents, toxic discharge, and unpredictable compliance risk with water-based systems certified to ZDHC MRSL v3.1 at Level 3, the program's highest tier.

Sustainability-first chemistry

Water-based, ZDHC compliant, no VOCs, zero microplastics — with fully biodegradable in-house lines

In-house R&D

Six proprietary product lines, continuously reformulated

Technical partnership

Lab testing, shade matching, and on-site support

Our Approach

The way we work

Listen, formulate, prove
We start with your substrate and your process. Then we formulate, match shades, test in our lab, and support you on the production floor — until it runs right.

Chemistry is more than colour — it's compliance, hand-feel, and cost per metre. Every formulation has to earn its place on your line.
02/
We believe in engineered solutions over quick fixes. Each project is a chance to replace legacy chemistry with something cleaner that performs better.

Performance is proven, not promised — spectrophotometry, fastness testing, and print trials before anything ships.
Every project begins with your substrate and your process.

Chemistry is more than colour — it's compliance, hand-feel, and cost per metre. Every formulation has to earn its place on your line.
02/
We believe in engineered solutions over quick fixes. Each project is a chance to replace legacy chemistry with something cleaner that performs better.
03/
Performance is proven, not promised — spectrophotometry, fastness testing, and print trials before anything ships.
Every project begins with your substrate and your process.
Consultation, customisation, lab testing, and on-site technical support — delivered by a team that's invested in your production outcomes, not just the purchase order.
