Aluminium paste price manufacturers

Selecting the correct grade depends on the desired visual effect and surface protection. Leafing Aluminium Paste is ideal for anti-corrosion coatings and roof paints as the flakes float to the surface to form a reflective barrier. Non-leafing Aluminium Paste is preferred for automotive and high-end industrial coatings because it distributes evenly throughout the film, allowing for better inter-coat adhesion and a metallic 'flip-flop' effect. Always specify the median particle size (D50); finer particles (5-15μm) provide high opacity and a silk-like finish, while coarser particles (20-60μm) offer higher brilliance and sparkle.

Buyers must verify the Solid Content (typically 65%-75%) to ensure they are not paying for excess solvent. The Solvent Type (usually Mineral Spirits or High Flash Naphtha) must be compatible with your resin system to avoid precipitation. Additionally, check the Sieve Analysis (residue on 325 mesh); high-quality pastes should have a residue of less than 0.1% to prevent surface defects and nozzle clogging in spray applications.

Since Aluminium Paste is a chemical product, it must comply with REACH (EU) or TSCA (USA) regulations. For environmental safety, ensure the product meets RoHS and VOC (Volatile Organic Compounds) limits. If used in food packaging or toys, it must adhere to EN71-3 or FDA requirements regarding heavy metal migration. Always request a current Material Safety Data Sheet (MSDS) and a Certificate of Analysis (COA) for every batch.

Aluminium Paste has a limited shelf life, typically 6 to 12 months. It is highly sensitive to oxidation and moisture. Buyers should avoid overstocking and ensure the supplier uses air-tight steel drums. Storage must be in a cool, dry, and well-ventilated indoor area (15°C-25°C). If the paste dries out or 'cracks' inside the drum, it loses its dispersibility and metallic luster, rendering it useless for high-quality finishes.

Aluminium Paste is classified as a Class 4.1 Flammable Solid (UN 1325) or Class 3 Flammable Liquid depending on the solvent. It requires Dangerous Goods (DG) packaging and specialized handling. Ensure your freight forwarder is experienced in DG cargo and that the supplier provides a UN-certified drum. Shipping costs will be higher than general cargo, so factor this into your Total Cost of Ownership (TCO).

Price is heavily influenced by the global price of aluminium ingots and solvent costs. To secure better rates, propose a long-term supply contract rather than one-off spot purchases. Ask for a tiered pricing structure based on volume (e.g., 1-ton vs. 5-ton orders). On Made-in-China.com, prioritize Diamond Members or Audited Suppliers who have undergone third-party verification of their production capacity and financial standing.

To ensure transaction security, use Secure Payment services provided by the platform. For quality control, hire a third-party inspector (like SGS or Intertek) to perform a Pre-Shipment Inspection (PSI). They should specifically test for non-volatile matter content and perform a draw-down test to compare the sample's brightness and color against your gold standard. Never bypass the platform's communication tools to ensure a digital trail exists for dispute resolution.

Check for Anti-Dumping Duties (ADD) in your specific country; some regions impose high tariffs on aluminium-based pigments from certain origins to protect local industries. Verify the HS Code (typically 3212.90) with your local customs broker to determine the exact import duty and VAT. Ensure all labels are in the local language and include the necessary GHS (Globally Harmonized System) hazard pictograms to avoid customs seizures.
