About TWA IndiaNeed a TDS or SDS?
We hold manufacturer technical datasheets and safety datasheets for the brands we distribute — Fosroc, Sika, Dr. Fixit, MC-Bauchemie, STP, Soudal and our own Dseal range.
Resources — Frequently Asked.
Where can I get the TDS or SDS for a product you stock?
WhatsApp the product name to +91-9310997953. We send the manufacturer’s TDS/SDS PDF the same day for anything in the Fosroc, Sika, Dr. Fixit, MC-Bauchemie, STP, Soudal or Dseal range.
Do you charge for technical guidance or product selection?
No. Send the structure, the symptom and photos, and our team — led by a concrete technologist practising since 1987 — will recommend a full system, not just a pack. Specification help is the core of how we sell; see our application services.
Are these guides brand-neutral?
We stock every major brand side by side, so we have no reason to push one. The guides name specific products only where the source data supports them — and where two brands solve the same problem, we say so and let the site conditions decide.
