Anticorrosive coating
Pipes, ships and steel bars are in a humid and corrosive environment for a long time, silane coupling agent can effectively improve the anti-corrosion performance of powder coatings: On the one hand, it can better combine the pigment, filler and resin in the coating to improve the corrosion resistance of the coating; on the other hand, it can block the interface between the coating and the substrate by coupling, preventing the migration and penetration of water molecules along the interface, and reduces the peeling and electrochemical erosion of water molecules by the coating.
Advantages
●Reacts with the hydroxyl groups on the surface of substrates to form chemical bonds, which can significantly improve the adhesion of powder coatings.
●Improve the corrosion resistance of the coating by better bonding the pigment, filler and resin inside the coating.
●Closing the interface between the coating and the substrate, prevent migration and penetration of water molecules along the interface, reduce the peeling and electrochemical erosion of water molecules on the coating
