ZD6330 Graphene Epoxy Micaceous Iron Oxide Intermediate Coat belongs to epoxy paints and is used as an intermediate coat. It can serve as the intermediate layer and sealing coat for high-performance anticorrosive paints such as epoxy zinc-rich primer and inorganic zinc-rich primer, to enhance the shielding and protective performance of the entire coating system. A two-component epoxy anticorrosive paint/intermediate coat composed of epoxy resin, nano-graphene, micaceous iron oxide anticorrosive pigment and polyamide curing agent. Parameters on this page: volume solids 65 ± 3%, dry film thickness 80/100/150 µm, theoretical spreading rate 0.357 kg/m².

ZD6330 Graphene Epoxy Micaceous Iron Oxide Intermediate Coat
A two-component epoxy anticorrosive paint/intermediate coat composed of epoxy resin, nano-graphene, micaceous iron oxide anticorrosive pigment and polyamide curing agent.
Due to the presence of nano-graphene and a large amount of flaky micaceous iron oxide, a "labyrinth" effect is formed in the film, so the coating film has excellent shielding and anticorrosive performance. Excellent resistance to chemical atmosphere, industrial atmosphere and marine atmosphere, and good resistance to seawater, salt, weak acids and weak alkalis. Long recoating interval.
May be used as an intermediate and sealer over epoxy zinc-rich primers, inorganic zinc-rich primers and other high-performance anticorrosives to enhance the barrier and protective properties of the whole coating system; as an anticorrosive primer for steel structures; as a surface-barrier anticorrosive intermediate coat for concrete and other structures; and as a maintenance primer over existing coatings where compatibility permits.

| Bare steel surface | Remove grease from the surface with a suitable cleaner, and rinse off salts and other contaminants with fresh water. Remove weld slag, and grind welds and sharp edges smooth. Abrasive blast clean to Sa 2.5 (ISO 8501-1); the ideal surface roughness is Rz 30–75 µm (medium roughness on the ISO 8503-1 comparator). Apply within 4 hours of blast cleaning. |
|---|---|
| Shop-primed surface | Welds, heat-corrected areas and damaged areas must be blast cleaned to Sa 2.5 (ISO 8501-1) or cleaned with power tools to St 3. |
| Primed surface | Clean, dry and free of zinc salts and contaminants. |
| Repair | Thoroughly remove grease from the surface with a suitable cleaner, and wash off salts and other contaminants with high-pressure fresh water. Remove rust and other loose material by blast cleaning; alternatively, grind small rusted areas with power tools. |
Application environment temperature 5–38 °C, relative humidity not more than 85%, and the steel surface temperature should be at least 3 °C above the dew point. Do not apply outdoors in adverse weather such as rain, fog, snow, strong wind and heavy dust;
In hot summer weather, guard against dry spray; provide ample ventilation during application and drying in confined spaces;
At application environment temperatures of -5 to 5 °C, use a low-temperature-curing product or take other measures to ensure proper film curing.
| Mixing | This product is supplied as two containers forming one unit. Stir the base thoroughly with a power mixer, add the curing agent in the specified ratio, stir again with a power mixer, and add the recommended thinner to adjust to a suitable application viscosity. Once mixed, use within the specified pot life. |

Note: the above data are measured under well-ventilated conditions, at typical film thickness and 75% relative humidity, and are for reference only.
Actual drying times and the interval before recoating may be longer or shorter depending on film thickness, ventilation, humidity, the underlying paint, requirements for early handling and mechanical strength, and other factors.
| Preceding coat | Zinc silicate primers, epoxy zinc-rich primers or other epoxy primers; it may also be applied directly to steel derusted to Sa2.5. |
|---|---|
| Subsequent coat | Epoxy, polyurethane, fluorocarbon, polysiloxane topcoats, and similar. |
When overcoating inorganic zinc-rich (zinc silicate) primers, thin with 20–50% thinner and first apply a thin mist coat, then spray to the specified film thickness. When curing at low temperatures (10 °C or below), mix the paint thoroughly and allow a pre-reaction time of 30 minutes before use. Because the product contains micaceous iron oxide pigment, after long-term exterior exposure the rough surface may hold impurities, which shall be removed thoroughly before overcoating with the topcoat. During application, or shortly after application, condensation or a sudden temperature drop will cause whitening, tackiness and poor adhesion of the subsequent coat.
