IS 6012:2018 is the Indian Standard (BIS) for inorganic zinc rich paint (potassium silicate based). IS 6012 covers inorganic zinc rich primer — the highest-performance anti-corrosion primer. 75%+ zinc dust provides cathodic protection. Used on bridges, offshore, and industrial steel.

Specification for inorganic zinc rich primer for corrosion protection of steel in aggressive environments.

4Key values 1Tables 1FAQs

Practical Notes

! Must blast to Sa 2.5 — won't adhere to hand-cleaned surfaces.

! Apply in dry conditions — moisture causes mud-cracking.

! Overcoat with epoxy/polyurethane only, NOT alkyd.

Frequently referenced clauses

Cl. 3 — Zinc dust min 75% in dry film

Cl. 4 — Binder: potassium silicate

Cl. 5 — DFT 75-100 µm

Cl. 6 — Salt spray resistance

Frequently Asked Questions1

Inorganic vs organic zinc primer?+

Inorganic: silicate binder, 75%+ zinc, better heat resistance (400°C), harder. Organic: epoxy binder, 60-80% zinc, easier application.
