This 400ml thickened tinplate empty spray paint can is engineered exclusively for hardware coating applications, including metal surface spraying, rust-proof coating, and industrial hardware finishing. Crafted with heavy-duty tinplate and precision manufacturing, it delivers superior pressure resistance, corrosion resistance, and leak-proof performance, perfectly adapting to the high-pressure filling requirements of hardware coating sprays (such as acrylic, epoxy, and anti-rust paints). Ideal for coating manufacturers, hardware processing factories, and industrial suppliers, this can ensures stable storage and efficient spraying, providing a reliable packaging solution for professional hardware coating scenarios.
- Thickened Tinplate for Enhanced Durability
It resists extrusion, impact, and deformation during transportation and stacking, suitable for the rough handling of industrial hardware workshops. The service life is extended by over 50% compared to ordinary cans.
- High-pressure Resistance for Hardware Coating Sprays
The integrated stamping forming process eliminates weak welds, withstanding a filling pressure of ≥3.0MPa and passing a 48-hour pressure holding test without leakage. It is fully compatible with high-pressure propellant-containing hardware coating sprays, avoiding can body expansion or rupture risks during storage and use.
- Dual Anti-corrosion Coating for Inner Wall
The inner wall is coated with a two-layer epoxy-phenolic anti-corrosion coating, non-reactive with acidic, alkaline, and solvent-based hardware coating formulas. It effectively prevents chemical reactions between the tinplate and paint, ensuring the purity of the coating and avoiding paint discoloration or deterioration.
- Precision Nozzle & Leak-proof Sealing Design
Equipped with a professional brass core spray nozzle that features adjustable spray patterns (mist/stream) to meet different hardware surface coating needs. The can mouth is sealed with a high-density nitrile rubber gasket and a crimped lock ring, achieving 100% leak-proof performance, even during inverted spraying operations.
- Customizable & Industrial Bulk Supply
Supports custom printing of product specifications, usage instructions, and brand logos; offers matte/glossy surface treatment to enhance brand recognition. Factory-direct pricing with tiered discounts for large industrial orders.
