The material
How this grade works and where it fits — exact parameters are defined in the TDS.
This product is a one-component bake-curing coating (a two-component self-drying curing version can also be formulated to customer requirements). It is composed of nano organotitanium polymer, auxiliary resins, graphene and other materials, giving the coating greatly improved thermal conduction/heat dissipation and anti-corrosion performance. It is therefore a new type of high-efficiency, energy-saving anti-corrosion coating material — a specialty coating developed specifically for industrial heat exchangers.
A thermally conductive, energy-saving, non-fouling, anti-corrosion coating for industrial heat exchangers: (1) in severely corrosive environments, a composite coating system can be applied for long-term protection; (2) recommended for protective coating service in high-temperature acidic environments at ≤300 °C; (3) protective coating for heat-dissipation systems of household appliances, LED energy-saving lamps, automotive engines, etc.
Model variants: EK-D14D — primer; EK-D14M — topcoat.
Choose this grade for heat-exchanger surfaces: a titanium-based graphene alloy coating for -30…300 °C duty, one-component bake-curing (a two-component self-drying version can be formulated on request).

Substrates & storage
Compatibility and handling essentials — confirmed per grade in the TDS and SDS.
Suitable substrates
Steel and stainless steel
Aluminium and other metals
Glass and ceramics
Stone and mineral surfaces
Carbon steel, stainless steel, cast iron, aluminum alloy, titanium alloy, high-temperature alloy steel, glass-ceramic plate, ceramics, cement and other materials. Note: the coating formulation differs for different substrates; within a certain range, it can be adjusted to match the substrate and its service conditions.
Storage, packaging & transport
Store in accordance with national regulations. The storage environment should be dry, cool and well ventilated, away from heat and ignition sources. Packaging containers must be kept tightly sealed and placed with care.
Storage temperature must be maintained between 5 °C and 30 °C; shelf life is 6 months.
Opened, partially used coating must be resealed tightly with the container lid for storage.
Mixed coating that is not used up cannot be reclaimed and should be disposed of in accordance with local regulations.
Product past its shelf life may be used only after testing confirms it still meets specifications.

Standard process: Surface cleaning → Abrasive roughening → Cleaning and blow-off → EK-D14 treatment → Curing
Abrasive roughening. Before coating, sand or blast the substrate surface to remove rust, dust, dirt and other contaminants adhering to the workpiece surface. Roughening has a significant effect on coating performance; Sa2.5 is optimal, with a minimum of St3 grade free of mill scale (GB/T 30790.4-2014), so pay close attention to this step.
Cleaning. Use a dedicated cleaning agent or degreaser to remove oil, dust and other residues remaining on the roughened surface.
Substrate drying. Before coating, ensure the substrate surface is dry and clean.
Coating mixing. This product is one-component; take an appropriate amount of coating according to the specified ratio, add thinner to dilute, stir until thoroughly and uniformly mixed, and filter through a 200-mesh screen before use.
Application method. For laboratory spray application, a spray gun with a 1.0 nozzle gives better appearance and uniformity. Apply the primer first; after baking dry, apply the topcoat.
Curing. Baking schedule: 150 °C, 20–30 min; 180 °C, 20–30 min.
Note: This product is a two-component ambient-curing product; use the mixed coating within 6 hours. For longer application sessions, clean application tools thoroughly to prevent them from setting. Application in a single spray pass is recommended; dry film thickness should not exceed 50 µm, otherwise coating film performance will decline.
