01Who We Are
Thirty Years of Industrial Chemistry. Zero Stock Formulations.
MacroCoats engineers conversion coatings around your operation — not off a shelf. Since 1993, we've served Indian Railways, automotive OEMs, fastener manufacturers, and heavy engineering facilities. Every formulation is built around your water chemistry, metal substrate, throughput targets, and compliance obligations.
The MacroCoats Approach
We Begin With Your Constraints.
Most suppliers deliver a concentrate and leave. MacroCoats engineers the full pre-treatment system — from your first rinse tank to your final passivation stage. The result holds specification across every shift, every operator, and every season.
