ZD6310-Z850 Cold-spray Zinc Coating

Product description

A two-component, high-solids heavy-duty anticorrosive coating composed of special modified resin, pure thin graphene, zinc dust, inorganic fillers, solvents and additives.

Key features

Complies with the performance standard HG/T 5573-2019 Graphene Zinc Dust Coatings;

High spreading rate, saving roughly 15% paint consumption compared with epoxy zinc-rich;

Mature and stable coating systems, high adhesion and high application tolerance;

The film has high anticorrosive performance and can replace traditional coatings such as epoxy zinc-rich in C2–C5 environments;

Intended use

As a primer for blast-cleaned bare steel in medium to severe corrosive environments, such as steel structures, bridges, port machinery, offshore platforms, construction machinery, storage tanks, pipelines and power facilities. Used with high-performance paints, it further improves the anti-corrosion performance of the coating system;

Suitable for approved zinc-rich shop primer surfaces to be retained;

Suitable for repair of damaged areas of galvanised parts or zinc silicate primer coatings;

For maintenance, its cathodic protection anti-corrosion effect is achieved only on surfaces prepared to bare steel.

Application instructions

Suitable substrates and surface preparation

New steelRemove 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 the primer within 4 hours of blast cleaning.
Shop-primed surfaceWelds, heat-treated areas and damaged areas must be blast cleaned to Sa 2.5 (ISO 8501-1) or cleaned with power tools to St 3. Only sound, approved zinc-rich shop primer may be retained. When exposed to humid conditions, zinc salts form on the zinc-rich primer surface; before recoating, remove soluble zinc salts with fresh water and remove white rust (zinc corrosion products) with a stiff brush. If the zinc-rich primer is damaged over a large area, full blast cleaning is recommended.
RepairThoroughly 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 and touch up bare areas with this product.

Application and curing conditions

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;

Paint mixing

MixingThis 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.
