Tunnel nano-silicon anion coating primer can protect corrosion-resistant parts from intrusion and resist damage from various complex acids and alkalis. It is used on surfaces of various large steel structures such as ships, highway guardrails, ports, open-air machinery, transmission towers, offshore drilling platforms, chemical open-air storage tanks, bridges, oil field drilling equipment, and containers.

Tunnel nano-silicon anion coating primer application method: Airless spraying: nozzle orifice; air spraying: brushing/rolling is suitable for small areas; maturation time: use after opening and fully stirring evenly, use after maturation time; surface treatment by methods such as shot blasting or sandblasting; the protective performance that the product can exert. Tunnel nano-silicon anion coating primer is used for surfaces requiring protection such as chemical equipment, oil pipelines, marine facilities, ships and vehicles, metallurgical mines, various mechanical equipment and facilities, steel structures, storage tanks, containers, bridges, underground engineering, as well as protection of ship and dock waterline areas.

Tunnel nano-silicon anion coating primer, in order to control the quality of the substrate surface and meet the requirements of different types of products, many have established substrate standards. The requirements for different primers are as follows: the surface can form a certain roughness, which allows the paint film to have adhesion; if the surface roughness is too great, it will consume excessive product.
