Tunnel nano-silicon negative ion coating primer protects corrosion-prone areas from intrusion and resists damage from various complex acids and alkalis. It is used on surfaces of various large steel structures such as ships, highway guardrails, ports, outdoor machinery, transmission towers, offshore drilling platforms, chemical outdoor storage tanks, bridges, petroleum field drilling equipment, and containers.

Tunnel nano-silicon negative ion coating primer application method: Airless spraying: nozzle orifice; air spraying: brushing/rolling suitable for small areas; curing time: use after opening and fully stirring evenly, apply after curing time; surface treatment methods such as shot blasting or sandblasting should be performed to enable the product to achieve its protective performance. Tunnel nano-silicon negative ion coating primer is used for surfaces requiring protection such as chemical equipment, oil pipelines, marine facilities, ships and vehicles, metallurgical mining machinery, steel structures, storage tanks, containers, bridges, underground engineering, as well as protection for ship and dock waterline areas.

Tunnel nano-silicon negative ion coating primer, to control substrate surface quality according to the requirements of different product types, many have established substrate standards. Requirements for different primers: the surface can form a certain roughness to ensure paint film adhesion; if the surface roughness is too high, it will consume excessive product.
