ZINC RICH ANODE EPOXY PRIMER – 2025 RECIPE
Rustbuster Zinc Rich Epoxy-Anode Primer – Superior Cathodic and Barrier Protection
Rustbuster’s Zinc Rich Epoxy-Anode Primer delivers top-tier corrosion protection for steel surfaces prepared to St3 standard (blast cleaned or power tool cleaned). This high-performance primer plays a crucial role in a rustproofing system when used alongside Armaguard Epoxy Mastic, Custom Epoxy Primer, or other premium coatings.
Formulated with 93% zinc solids embedded in a durable epoxy resin, this primer offers both barrier and cathodic protection. Specifically, when scratches penetrate the topcoat and primer to expose bare metal, the zinc reacts with the steel substrate. This reaction produces zinc salts that effectively “self-heal” the damaged area, restoring the protective barrier and preventing rust formation.
Cathodic protection is a proven and effective method for corrosion control in automotive and industrial applications, which helps extend the lifespan of metal components.
Key Benefits:
-
Contains high zinc content (93%) to enhance corrosion resistance
-
Acts as a self-repairing primer that protects scratches from rust
-
Ideal for steel surfaces cleaned to St3 standard
-
Fully compatible with Rustbuster Armaguard Epoxy Mastic and Custom Epoxy Primer
-
Creates a durable barrier against moisture and oxidation
In summary, protect your vehicle or equipment with Rustbuster’s Zinc Rich Epoxy-Anode Primer—engineered to provide lasting defence against corrosion even in the most demanding environments.

| Product description | 2 pack isocyanate-free epoxy zinc-rich primer. |
| Pack description | A 1.25 ltr pack includes 850ml of base, 150ml of hardener and 250 ml of thinner.
A 6 ltr pack includes 4.25 ltr of base, 0.75 ltr of hardener and 1 ltr of thinner. |
| Mix ratio | Mix 8.5 parts component A (zinc) to 1.5 part component B (hardener) by volume. |
| Coverage | Can be applied to steel as low as 5c. The steel must be at least 3 degrees above the current dew point. (See our dew point calculator.) |
| Thinning | Use only the epoxy thinner supplied, from 5 to 20% max. |
| Application | Brush or spray on a blast-cleaned surface. |
| Spraying | Minimum 1.8mm nozzle or an HB (high build) primer set up. Test atomisation on a test panel first. Viscosity will vary, i.e. thicker in colder temperatures. Data correct at 20c. |
| Pot life | Pot life is the time from mixing the two components to the point at which the mixed paint is no longer usable. For Zinc Rich Epoxy-Anode, you have 2.5 hours of pot life once mixed at 20c – longer at colder temperatures. |
| Shelf life | We recommend storing upside down in a dry place at around 20c. In these conditions, the product has a shelf life of 12 months.
Do not store below 20c as this can affect performance. |
| Disposal | Allow the mix to cure in your mixing cup and throw it away as dry waste. |
| Cleaning | Clean up with standard thinner or gun wash. Do not thin the paint with standard thinner as this will affect the paint cure. |
| Safety | Use in a well-ventilated atmosphere. Use a respirator face mask when spraying or brushing in an enclosed space. Please see the MSDS (material safety data sheet) in our data sheet area.
Wear suitable protective clothing, gloves and eye protection. |
