AEROCOAT®
ZINC-ALU GALV
High-Performance Zinc-Rich Corrosion Protection for Steel & Galvanized Surfaces
AEROCOAT® Zinc-Alu Galv is a premium organic-bound, zinc-rich protective coating designed to shield steel and galvanized surfaces from rust, corrosion, and environmental attack. Formulated with over 60% zinc in the dry film, this coating provides powerful sacrificial protection, forming a long-lasting barrier that prevents corrosion from spreading—even on damaged or abraded areas.
Pack Size: 400 ml (Pack of 12)
Features & Benefits
- Excellent corrosion protection with >60% zinc in dry film
- Highly abrasion resistant for demanding environments
- Adheres strongly to abraded steel & galvanized surfaces
- Prevents rust creep on damaged or repaired areas
- Can be used as a primer or topcoat
- Provides durable galvanic barrier protection
Intended Uses
Primer/Topcoat For Galvanized Steel
AEROCOAT® ZINC-ALU GALV works great as a protective anti-corrosive primer on galvanized steel before applying a topcoat & can be used as a topcoat on galvanized steel to provide barrier/passive protection & inhibitor/sacrificial protection.
Primer/Topcoat For Steel
AEROCOAT® ZINC-ALU GALV can be used as a protective anti-corrosive primer or topcoat on steel & will provide barrier/passive protection & inhibitor/sacrificial protection.
How it Works
Passive/Barrier Protection
Barrier protection is the most widely used method of corrosion protection and barrier protection properties act by isolating the base metal from the environment and are highly effective in keeping moisture and corrosive agents from reaching the surface. A coating with only barrier protection properties will protect the surface as long as the coating is in tact. In order for the coating to protect as effectively as possible it should have very good adhesion and mechanical resistant properties.
With AEROCOAT® ZINC-ALU GALV there are 2 ways in which the barrier/passive protection occurs; the first is from the binder that adds additional protection to the zinc and is effective in creating a barrier to moisture & the second is the layer of zinc oxide protecting the steel surface & any surface exposed from mechanical damage thus preventing any rust creep under the paint film.
Inhibition/Sacrificial Protection
Inhibition/sacrificial corrosion protection is the process of zinc oxidising to form a moisture impervious layer of zinc oxide / zinc salts. As zinc is exposed to the elements, the zinc layers corrode and wear away, as it wears away more zinc oxide layers take formation (sacrificial). Zinc is naturally porous and when the zinc oxide layers form, the porosity of the zinc is filled with zinc oxides / zinc salts.
This process of filling the porosity dramatically reduces the rate at which the layer sacrifices itself. In addition to the formation of zinc oxide layers; AEROCOAT® ZINC-ALU GALV contain high performance binders which add additional protection to the zinc particles within the zinc oxide / zinc salts layer. These high performance binders act as corrosion inhibitors to the zinc. This inhibition/sacrificial protection system essentially blocks/inhibits the corrosive agents from reaching the steel.
