Alud brand galvanized pipe epoxy zinc yellow primer dense metal anti-corrosion paint

Description :

　　Product features: The surface of galvanized pipes is relatively smooth, and due to zinc being an active metal, it is easy to undergo saponification reaction with the base material in ordinary coatings (such as alkyd paint) to generate zinc soap, which destroys the bonding force between the zinc surface and the coating, leading to weak adhesion of the coating film. Therefore, protective coatings should choose coatings with strong adhesion, passivation, corrosion inhibition, and shielding effects as the bottom layer, and coatings with good corrosion resistance, weather resistance, and decorative properties as the surface layer.

　　Selection of coating matching:

　　Choose SHF-2D epoxy zinc yellow primer with passivation, corrosion inhibition and shielding effects as the transition layer, and choose fluorocarbon anti-corrosion topcoat with superior comprehensive performance such as corrosion resistance and weather resistance as the decorative surface layer.

　　Construction technology:

　　1. Surface treatment

　　Remove surface dust and use organic solvents to remove oil stains, but be careful to change the cloth frequently to prevent re staining; Use a wire brush or sandpaper to remove rust from corroded areas.

　　2 Painting process

　　Due to the presence of numerous micropores on the surface of galvanized pipes, SHF-2D epoxy zinc yellow primer should be slightly diluted, typically with a total amount of 10% to 20% diluent added to better seal these micropores.
