ReadAnti-Corrosive & Protective Coatings
ALSTRONG AC is a polyurethane-blended, long-lasting corrosion preventive coating for the protection of exposed steel reinforcement and iron. Self-priming and tolerant of lower grades of steel preparation — it penetrates into existing rust to combine it with the coating all the way down to the original metal surface. Provides excellent resistance to corrosion, chemicals and weathering in industrial, coastal and chemical environments. Also used as an anti-carbonisation coat on exterior and internal concrete structures to prevent CO₂-induced reinforcement corrosion. Fully compatible with the ROOFBOND and ROOFCRETE concrete repair systems.

ALSTRONG AC is a rebar anti corrosive coating blended with polyurethane for exposed steel reinforcement and iron. It is self-priming and tolerates lower grades of steel preparation, because it penetrates existing rust and combines it with the coating down to the original metal. You apply it by brush or spray, normally in two coats.
Coat cleaned bars, then place repair mortar or concrete over them.
Self-priming coat for steel and iron exposed to the atmosphere.
Applied on concrete to keep carbon dioxide from corroding the reinforcement.
Resists corrosion, chemicals and weathering in industrial settings.
Corrosion preventive coat for steel and reinforcement in coastal exposure.
Chemical resistance for steel and iron in plant areas.
Works as the primer step before ROOFBOND and ROOFCRETE repairs.
When rusted rods show up in a slab repair, ALSTRONG AC gives corrosion protection for steel reinforcement before the new mortar goes on. Coverage is 60–70 sq.ft per litre per coat by brush or spray. It is touch dry in 30 min at 20°C and ready for the second coat after 45 min at 20°C, or 35 min at 35°C. Packs run from 500 ml to 210 litres, with a shelf life of 2 years. Apply within 3–4 hours of surface preparation.
Armstrong Chemicals supplies ALSTRONG AC to sites across Telangana, Andhra Pradesh, Karnataka, Kerala and Tamil Nadu, including Hyderabad, Vijayawada, Bengaluru, Kochi and Chennai.
A PU-blended, self-priming corrosion preventive coating that penetrates existing rust down to the original metal surface — plus anti-carbonisation protection for concrete structures against CO₂-induced reinforcement corrosion. Compatible with ROOFBOND and ROOFCRETE concrete repair systems.
Get a QuoteCorrosion from direct exposure, and carbonation-induced corrosion when CO₂ penetrates concrete and reduces the pH around the reinforcement — attacking the passive oxide layer that normally protects steel. Both require treatment before structural repair is viable.
Self-priming PU-blended coating that penetrates existing rust to the original metal surface, plus anti-carbonisation capability for concrete structures — a single product addressing both corrosion threats before and after concrete repair.
ALSTRONG AC is self-priming and tolerant of lower grades of steel preparation — it does not require blast-cleaned white metal to bond effectively, making it practical for in-situ structural repairs where perfect surface preparation is not achievable.
Applied to exterior and internal concrete walls and structures, ALSTRONG AC acts as an anti-carbonisation coat — blocking CO₂ penetration into the concrete cover and preventing the pH reduction that drives reinforcement corrosion.
Pairs with ROOFBOND SBR and ROOFCRETE EP for the full repair system.
With anti-carbonisation capability for concrete structures.
PU-blended, self-priming and tolerant of lower steel preparation grades — penetrates existing rust to the original metal surface for dependable long-lasting corrosion protection.
Applied to exterior and internal concrete structures as an anti-carbonisation coat — blocking CO₂ penetration that drives reinforcement corrosion in carbonated concrete cover.
Designed to work within the ROOFBOND and ROOFCRETE structural repair systems — the protective primer step before concrete repair mortar is applied over treated reinforcement.
High performance and long-lasting resistance to aggressive corrosion, industrial pollution, coastal environments, chemical attacks and weathering — plus UV resistance.
Prepare steel or reinforcement surface — clean and dry, free from loose rust, scale, oil and grease
Apply ALSTRONG AC within 3–4 hours of surface preparation — do not leave prepared surfaces exposed longer than necessary
Apply by brush or spray, ensuring thorough coverage of all surfaces
Touch dry: 30 min @ 20°C / 20 min @ 35°C
Apply second coat after first is fully dry (45 min @ 20°C / 35 min @ 35°C)
Overcoat or apply concrete/mortar repair material before the coated reinforcement is exposed unnecessarily to the atmosphere
Available in 500ml, 1, 5, 10, 20, 30 & 210 Litre packs. Shelf life of 2 years from manufacture.
Apply within 3–4 hours of surface preparation — do not leave cleaned steel or reinforcement exposed to the atmosphere longer than necessary before applying ALSTRONG AC or overcoating.
Fully compatible with the ROOFBOND SBR and ROOFCRETE EP concrete repair systems — designed to be applied as the protective primer step on exposed reinforcement before structural concrete repair is carried out.

ALSTRONG ZP 777 is a high-performance, zinc-rich primer for anti-corrosion protection and rust conversion on steel and iron. Highly penetrative, it encapsulates rust and delivers excellent adhesion and bonding to steel and concrete structures, while protecting against aggressive corrosion, industrial pollution, coastal environments, chemical attacks, weathering and water. Suitable for brush and spray application, and overcoatable with rubber, acrylic, PU, epoxy and water dispersion coatings.

View DetailsALSTRONG RC is a high-performance, self-priming rust converter and rust encapsulating coating for the protection of steel and iron against aggressive corrosion, industrial pollution, coastal environments, chemical attacks and weathering. When applied to a rusty steel surface, it chemically stabilises and converts adhering rust into an organo-complex compound within 30 minutes — forming a tough, porous, moisture-repelling coating with good mechanical stability, abrasion resistance, bond strength and excellent anti-corrosive properties. Salt spray resistance of 340 hours at 25 microns (ASTM B 117). Can be immediately overcoated with concrete, mortar, rubber, acrylic, PU, epoxy or water dispersion coatings.
