Aluminized Rust-preventive Weldable Coating
Bloxide® aluminized rust-preventive weldable coating is used to protect steel surfaces from rust, especially where extended periods of outside storage are anticipated. It protects prepared edges and surfaces prior to welding and other heat-joining methods, eliminating the need for secondary weld preparation on pipe flanges and joints. The aluminized product serves as an excellent weld-through primer and can be applied by brush, dip or spray with no special equipment or training. It is temperature-resistant to 800 F (427 C), and covers approximately 800 sq ft per gallon. Weldable Bloxide allows welders to strike an arc directly on the coating without removing the coating. It provides an aid to reducing inclusion and pinhole porosity. It leaves no residue or slag, and the aluminum-rich product assists in achieving X-ray quality welds. Bloxide aluminized, rust preventive weldable primer was certified in 2003 by American Bureau of Shipping (ABS) and Det Norske Veritas (DNV), the marine management systems certification agencies, for application on blast-cleaned steel plates and sections in marine construction and maintenance, and offshore fabrication industries. Bloxide can also be used for almost all coated welding fabrication, as it is free from lead, sulfur, zinc, cadmium, mercury, chlorine and other halogens.
