Chemical Raw Materials for Coatings and Inks: Driving Protection, Decoration, and Functionality

• Nitrocellulose (Granules): With a CAS No. of 9004-70-0 and molecular formula (C6H7O2(ONO2)3)n, this material falls under Hazard Class 4.1. It’s a core component for both coatings and inks, known for enabling quick-drying, hard films.
• Strontium Carbonate: Classified as general cargo, it has a CAS No. of 1633-05-2, molecular formula SrCO₃, and a purity of 97.52%. It enhances the protective capabilities of coatings.
• Barium Carbonate: Available in types like Granules Barium, Light Barium, and Heavy Barium, it has a CAS No. of 513-77-9, molecular formula BaCO3, 99.2% purity, and belongs to Hazard Class 6.1. It acts as a key protective filler against corrosion.
• Magnesium-Aluminum Alloy Powder: With a CAS No. of 12604-68-1, molecular formula Mg4Al3, and Hazard Class 4.1, it adds specialized functions like conductivity to coatings and inks.
• Thiourea: Boasting 99% purity, a CAS No. of 62-56-6, molecular formula CH4N2S, and Hazard Class 9, it works as a stabilizer and corrosion inhibitor.
• Aluminum Powder: This silver grey powder is in Hazard Class 4.1 with a minimum order quantity (MOQ) of 5 tons. It provides metallic luster and boosts corrosion resistance.

For Coatings

1. Film Formation: Nitrocellulose is critical here, as it creates quick-drying, hard films that form the base of many coatings. This ensures coatings set fast and maintain durability over time, whether on a car body or a furniture surface.
2. Protection Appearance: Aluminum Powder shines in this aspect. It adds an attractive metallic luster to coatings while strengthening their ability to resist corrosion—perfect for surfaces that need both visual appeal and long-lasting protection.
3. Corrosion Inhibition: Barium Carbonate and Strontium Carbonate act as protective fillers in primers (the base layer of coatings). They form a barrier that blocks moisture and harmful substances from damaging the underlying material, extending the life of the coated surface.
4. Specialized Functions: Magnesium-Aluminum Alloy Powder adds conductivity, making it ideal for functional coatings (such as those used in electronic devices). Thiourea, meanwhile, prevents corrosion and keeps the coating formula stable, ensuring consistent performance batch after batch.

For Inks

1. Film Formation: Just like in coatings, Nitrocellulose helps inks form quick-drying, hard films. This is essential for packaging printing, where inks need to set rapidly to avoid smudging during handling or shipping.
2. Visual Effects: Aluminum Powder brings metallic luster to specialty inks, making printed designs—like those on product labels or promotional materials—stand out with a glossy, eye-catching finish.
3. Functional Properties: Magnesium-Aluminum Alloy Powder provides conductivity to inks used in printed electronics. This enables the creation of flexible circuits or small electronic components on substrates like plastic or paper, supporting the growth of smart devices.
4. Stabilization: Thiourea acts as a corrosion inhibitor and stabilizer in metal-compatible inks. It prevents damage to metal surfaces (such as aluminum cans) that the ink is applied to, while also keeping the ink’s texture and color consistent.
