Multi-layer anti-corrosion coating technology petrolatum (PTC) protection layer made of four closely linked, namely corrosion petrolatum ointment, petrolatum corrosion tape, seal the buffer layer and the corrosion protection cover. Wherein the corrosion petrolatum ointment, petrolatum corrosion zone is a core part of the multi-layer coating of petrolatum corrosion technology, and efficient sustained release contains ingredients that can effectively prevent the erosion of corrosive media, steel structures, and construction with water . Seal buffer layer and corrosion protection cover has a good overall performance, not only to cut off the water, but also to resist damage mechanical damage to the steel structure.

1, for at low tide and high tide line line one meter to 2 meters waves splash zone and tidal zone, can provide long-lasting protection, at this stage the best waves splash zone protection technology

2, For other steel facilities in harsh environments, such as buried pipes, etc., can also provide good protection.
