Spray paint

Buyers should prioritize Resin Content and Pigment Quality, as these determine durability and coverage. For industrial applications, ensure the Solid Content is above 30% to reduce the number of coats required. Additionally, verify the Drying Time (Touch dry < 10 mins, Hard dry < 24 hours) and Adhesion Strength (tested via cross-cut test) to ensure the paint does not peel under environmental stress.

Due to the chemical nature of the product, you must verify MSDS (Material Safety Data Sheet) and SDS documentation. For the US market, compliance with ASTM D-4236 and VOC (Volatile Organic Compounds) regulations is essential. For the EU, ensure the product meets REACH and RoHS standards. Since spray paint is an aerosol, it must have a UN1950 certification for the transport of dangerous goods.

Request samples to test the Atomization Quality; a high-quality nozzle should provide a consistent fan-shaped spray pattern without spitting or clogging. Check for UV Resistance if the paint is for outdoor use to prevent fading. For specialized tasks, inquire if the supplier offers 360-degree valves that allow spraying at any angle, which is a hallmark of premium manufacturing.

Spray paint is categorized by function: Anti-rust primers for construction, High-temperature resistant paints (up to 600°C) for automotive exhausts, and Fluorescent or Reflective paints for safety signage. When sourcing on Made-in-China.com, specify the substrate (metal, plastic, or wood) to ensure the chemical formula is compatible with the intended surface.

Spray paint is classified as Class 2.1 Flammable Gas (Dangerous Goods). You must use a freight forwarder experienced in DG (Dangerous Goods) shipping. Ensure the packaging meets IMDG (International Maritime Dangerous Goods) codes, typically requiring double-walled corrugated cartons and specific hazard labels. Shipping via air is extremely restricted and costly; Sea Freight is the standard for bulk B2B orders.

Utilize the Secured Trading services on Made-in-China.com to protect your payment until the goods are shipped. Always conduct a Factory Audit or request a third-party inspection (like SGS or Intertek) to verify the supplier's Hazardous Chemicals Production License. This prevents the risk of customs seizing goods from unlicensed manufacturers.

Because the cost of spray paint is heavily influenced by raw material (solvents/propellants) and tinplate prices, consider long-term contracts to lock in pricing. For MOQs, suppliers usually require 7,500 to 10,000 units per SKU for custom lithographed cans. If you are a small buyer, negotiate for plain cans with adhesive labels to reduce the MOQ to 1,000 units.

Spray paint typically has a shelf life of 2 to 3 years. Ensure the production date is within the last 3 months before shipping. During transit and storage, containers must be kept in a cool, dry, and well-ventilated environment (below 45°C) to prevent pressure buildup and potential explosions in the shipping container.
