This product features excellent anti-rust performance, good compatibility with various coating resins, low oil absorption to improve coating leveling property, stable chemical properties that will not react with other coating additives, and meets low VOC environmental protection coating requirements. It solves the problem of high toxicity of traditional lead-based anti-rust pigments, provides efficient anti-corrosion protection for metal and wood coatings, and improves the service life of coating products with precisely controlled particle size to ensure uniform dispersion.
The product specifications are as follows: Purity ≥97.0%, Zinc content ≥55.0%, Moisture ≤0.8%, Water insoluble matter ≤0.5%, Oil absorption 20-25 g/100g, pH value 7.5-9.0, Particle size D50 25±3μm, Bulk density 0.7-0.9 g/cm³, Packaged in 50kg plastic woven bags with waterproof coating, stored in dry and ventilated warehouse, with a shelf life of 2 years.
It is mainly used as anti-rust pigment and functional filler in water-based anti-rust coatings, solvent-based steel structure coatings, wood coatings, architectural exterior wall coatings and automotive primer coatings. It is suitable for coating manufacturing enterprises, metal surface treatment factories, construction engineering teams, etc. It can be directly added to coating formulations to improve anti-corrosion performance and weather resistance, meeting modern coating production environmental protection requirements.
