Epoxy Zinc-Rich Anticorrosive Primer H06-4 is a zinc-rich primer, in the epoxy coating system. It is the ideal primer for epoxy intermediate coats and epoxy topcoats. A two-component high-build epoxy zinc-rich anticorrosive primer composed of zinc powder, epoxy resin and polyamide curing agent, additives and solvents. The film contains a large amount of metallic zinc powder, providing cathodic protection. Parameters on this page: volume solids 56 ± 3% (after mixing), dry film thickness 80 µm, theoretical spreading rate 314 g/m².

A two-component high-build, composed of zinc powder, epoxy resin and polyamide curing agent, additives and solvents,
Epoxy Zinc-Rich Anticorrosive Primer.
The film contains a large amount of metallic zinc powder, providing cathodic protection
Used for large bridges, port machinery, heavy machinery, oil extraction and mining equipment, buried pipelines,
hydraulic steel gates, workshop steel structures, oil storage tank exteriors, gas holder exteriors, areas above the ship waterline,
ship hulls and decks and other steel structures as an anticorrosive primer in heavy-duty anticorrosive systems. It is the ideal primer for epoxy intermediate coats
and epoxy topcoats.

The film of zinc-rich primer will develop zinc salts (basic zinc carbonate,
also known as white rust) on its surface after being left for a long time; therefore, it should not be exposed for long before the next coat is applied. If a longer application interval
is required, apply 842 Epoxy Micaceous Iron Oxide Anticorrosive Paint as a sealer as soon as possible to reduce the amount of secondary rust removal.
In a clean indoor environment for several months, or in a clean outdoor environment within 14 days,
no zinc salts will form on the film surface. However, in industrial or marine climate environments, zinc salts will
form quickly, so the interval before the next coat should be shortened as much as possible.
If zinc salts have formed on the film surface of H06-4 Epoxy Zinc-Rich Anticorrosive Primer, they must be removed by sweep blasting or mechanical rust removal
before applying the next coat.
| Recommended number of coats | 1 coat by airless spray, 50-80 µm dry film thickness; 2-3 coats by brush or roller. |

842 Epoxy Micaceous Iron Oxide Anticorrosive Paint, H53-31 iron red epoxy anticorrosive paint, H53-32 epoxy zinc phosphate anticorrosive
paint, H53-33 epoxy aluminium triphosphate anticorrosive paint, 546 epoxy bitumen extra-high-build anticorrosive paint,
846 epoxy bitumen high-build anticorrosive paint, chlorinated rubber anticorrosive paint, or topcoats of these types.
However, it must not be used with oil-based, alkyd or polyester paints.
Steel with mill scale: blast clean to Sa 2.5, surface roughness 30-75 µm. Or
pickle to remove all mill scale and rust, followed by thorough neutralisation, washing and passivation.
Mill-scale-free steel: abrasive blast clean to Sa 2.5, or grind with pneumatic or power abrasive discs to St 3
Shop-primed steel: carry out secondary rust removal on damaged film, rusted areas and white rust on the zinc-rich primer, removing all white rust and abrading to St 3.
When the outdoor application temperature is below 5 °C, the reaction between the epoxy and curing agent stops and application is not advisable; H06-4 Winter Grade Epoxy Zinc-Rich Anticorrosive Primer is recommended.
| Application method | Airless spray: Thinner 103, thinning 0-10% (by paint weight), nozzle tip 0.4-0.5 mm, spray pressure 15-17 MPa (approx. 150-170 kg/cm²). Air spray: not recommended for large areas, suitable only for small-area touch-up or small workpieces; Thinner 103, thinning 0-10% (by paint weight), nozzle tip 2.0-3.0 mm, air pressure 0.3-0.6 MPa (3-6 kg/cm²) |
|---|---|
| Roller/brush | Thinner 103, thinning 0-5% (by paint weight) |
| Cleaning solvent | Thinner 103 |
| Safety measures | See the Safety Data Sheet (MSDS) of Shanghai Kailin Paint Factory. |
| Packaging | Component A (base): 20 L drum, 32.5 kg; Component B (curing agent): 4 L drum, 3.2 kg |
| Shelf Life | 12 months |
The drying and curing time of Epoxy Zinc-Rich Anticorrosive Primer shortens as the temperature rises.
| The curing time at different temperatures is as follows: | ||||
| Temperature | 10°C | 15°C | 25°C | 30°C |
| Surface Dry | 50 min 40 min 30 min 15 min | |||
| Fully cured | > 20d | 15d | 7d | 5d |
At air temperatures between 5-10 °C, H06-4 Epoxy Zinc-Rich Anticorrosive Primer can be applied, but the curing speed is very slow.
Below 5 °C, application is not advisable because the reaction between the epoxy resin and the curing agent stops. At
In this case, application can be carried out in a coating shop above 5 °C, or H06-4 Winter Grade Epoxy Zinc-Rich Anticorrosive Primer may be used.
Adequate ventilation is required during the application and curing of H06-4 Epoxy Zinc-Rich Anticorrosive Primer.
