The core technical highlights of this product include its surface modification treatment, which improves the adhesion to metal substrates and the overall anti-rust performance of the primer, with a salt spray resistance of up to 500 hours, which is 30% higher than that of conventional pigments. It has low VOC content, complying with global environmental protection regulations, reducing environmental pollution during production and use. It solves the common problems of single color and insufficient anti-rust effect of traditional antirust primers, providing a dual solution of anti-corrosion protection and beautiful blue appearance for metal components. It is suitable for various metal anti-corrosion coating scenarios, improving the service life and aesthetic appearance of metal products.
Detailed technical parameters include a pH value of 8.0-9.0, a density of 4.0-4.1 g/cm³, volatile content of ≤0.6%, residue on 325-mesh sieve of ≤0.04%, cross-cut adhesion of ≤Grade 1, salt spray resistance of ASTM B117 ≥500h. The product is packaged in 25KG plastic woven bags, meeting the standard transportation and storage requirements for industrial anti-corrosion pigments.
This modified iron oxide blue pigment is widely applicable to antirust primers for steel structural bridges, automotive chassis anti-corrosion paint, hardware parts anti-rust coating, industrial equipment metal shell primer and container anti-corrosion coating. It provides both anti-corrosion protection and blue appearance decoration for metal components, improving the service life and aesthetic appearance of various metal products.
