Product Description

Organic Zinc Rich Primer is a two-component epoxy primer heavily loaded with metallic zinc dust, designed for advanced corrosion protection of steel and fabricated structures. Once applied on properly blast-cleaned steel, it cures to a dense adherent film where zinc particles remain in electrical contact with the substrate, delivering sacrificial cathodic protection with low permeability barrier resistance.

Ideal for severe atmospheric, marine, refinery, bridge, plant, offshore, and infrastructure steel protection systems.

Key Features & Benefits

• Dual protection mechanism
• High zinc loading cathodic protection
• Strong moisture / oxygen / chloride barrier

FAQS

Q1. Difference from inorganic zinc silicate?
Organic zinc-rich primers are easier to apply, faster drying, and more tolerant to conditions.

Q2. Surface preparation required?
Best on abrasive blast cleaned steel to Sa 2½ / Sa 3 with 50–75 micron profile.

Q3. Can it be used without topcoat?
Temporary protection possible, but epoxy/PU topcoat recommended for exterior durability.

Q4. Typical zinc content?
Usually around 80–85% metallic zinc in dry film.

Q5. Suitable for immersion?
Depends on product data sheet and full system design.

Q6. Can it repair damaged galvanizing?
Yes, widely used for galvanizing touch-up and repairs.
