Wet Surface Technology

When most anti-corrosive paints are applied to wet steel or other metal surfaces, water is trapped between the metal and the paint, thereby preventing the paint from bonding to the metal surface and causing the metal surface to continue to rust and accumulate corrosive lose particles. In addition when temperatures change, the trapped water expands and contracts as well as vaporizing, causing physical damage to the paint coating, eventually causing the coating to chalk. Therefore, dampness is a big hidden problem. Most coatings require the working surface to be dry and the coating to be applied when humidity is not too high. BW 9300 coatings on other hand, having a special technical advantage in that when it is applied to a wet surface, it bonds instantly to the metal surface and squeezes the water out. Any trapped water eventually evaporates by the means of molecule movement to the coating surface provided that any surface water is moving and the coating is not submerged in still water.

Build in Rust Converting Technology

　　BW 9300 coatings use a direct converting and chelate mechanism and do not rely on an added transforming agent or stabilizers. The technology uses a modified polymer, which reacts with the base metal and the rust, forming a composite layer, which is created by the polymer, the fillings, the converted rust particles and metal molecules. It provides a multi isolation layer to the base metal. When the base metal is chelated with this protection layer it forms a "Total isolation", thereby eliminating the iron exchange movement between the metal and the coating layer. The high density and stability and good insulation of the coating layer effectively blocks the irons from going through the layer, and as a consequence prevents any electrochemical reaction from outside. With the corrosive micro-current being reduced to virtually zero, the coating layer is thus able to provide super anti-corrosive, long lasting protection. In addition, as long as the polymer is there, it can continuously convert any possible newly formed rust and stablize it. Hence total protection is achieved through use of a better bonding, super anti corrosive coating.

Another added benefit of QUNLY BW9300 is that because the paint does not rely on an added agent for its chelation to the base metal, it leaves greater freedom for colouring and special function fillings.
