Functional Prepainted Steel for Sensitive Environments
Beyond standard colors, CNB develops functional coatings for industries that demand more than just aesthetics. Our specialty PPGI includes antimicrobial, anti‑static, self‑cleaning, heat‑insulating, and food‑grade finishes. By embedding active agents or conductive pigments into the paint, we transform ordinary coated steel into a performance material for pharmaceutical cleanrooms, electronics factories, food processing plants, and cold storage facilities.

Specialty Coating Portfolio

• Antimicrobial PPGI: Contains ceramic‑based silver ions; 99%+ reduction of E. coli and Staphylococcus aureus. Meets ISO 22196.

• Anti‑Static PPGI: Surface resistivity 10⁶–10⁹ Ω, prevents dust attraction and electrostatic discharge in electronic assembly areas.

• Self‑Cleaning PPGI: Hydrophilic coating lets rain wash away dirt, keeping building facades clean without manual cleaning.

• Food‑Safe PPGI: Certified under FDA, LFGB, and GB 4806.9; suitable for direct food contact surfaces, baking trays, and conveyors.

• Textured Finishes: Suede, embossed wood grain, wrinkled, grid, and brushed metal‑effect patterns for decorative panels.

Specifications

• Substrate: Electro‑galvanized or zero‑spangle HDG (for smooth finish) or GL (for outdoor food equipment).

• Total Thickness: 0.3mm – 1.2mm

• Paint: Custom formulated functional paints, applied 2‑coat/2‑bake or 3‑coat systems.

• Film Protection: Optional PE protective film for high‑gloss or textured surfaces.
