Tunnel nano-silicon negative ion 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 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, use after curing time; surface treatment by shot blasting or sandblasting and other methods, the protective performance that the product can exert, 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 mines, various mechanical equipment and facilities, as well as steel structures, storage tanks, containers, bridges, underground engineering, etc., and for the protection of ship and dock waterline areas.

Tunnel nano-silicon negative ion coating primer, in order to control the quality of the substrate surface, according to 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 roughness that allows the paint film to have adhesion; if the surface roughness is too large, it will consume excessive product.
