This 300ml moisture-proof empty spray paint can is tailor-made for hardware factory production lines, targeting small-area coating tasks such as hardware accessory rust-proofing, precision part finishing, and metal component touch-ups. Engineered with a dual moisture-proof barrier system and industrial-grade corrosion-resistant inner coating, it effectively isolates air and moisture to prevent paint caking, oxidation, and deterioration during storage and production. Designed for bulk supply, the can features a durable yet lightweight structure, making it ideal for high-volume use in hardware workshops. Fully compatible with solvent-based, water-based, and acrylic anti-rust paints, it is a cost-effective packaging solution for hardware manufacturers seeking stable quality and efficient production.
Key Features
Dual Moisture-proof Barrier System for Paint Stability
Equipped with a double-layer moisture-proof structure: the outer wall adopts a scratch-resistant hydrophobic coating to repel external moisture and water vapor, while the inner wall is lined with a sealed aluminum foil barrier to block air infiltration. This dual protection ensures zero moisture contact with the stored paint, preventing caking, discoloration, and oxidation even in high-humidity workshop environments. The can passes a 7-day high-humidity (90% RH) storage test with no paint quality changes, fully meeting the moisture-proof requirements of hardware factory production lines.
300ml Precision Capacity for Hardware Small-area Coating
The 300ml fixed capacity is precisely calibrated to the small-area coating demand of hardware accessories (e.g., screws, nuts, small metal brackets), covering 1–1.5 square meters per can. It eliminates paint waste caused by oversized packaging and reduces inventory pressure for hardware factories. The lightweight design (net weight only 75g) reduces hand fatigue during assembly line spraying operations, improving production efficiency for repetitive tasks.
The inner wall is coated with a high-adhesion epoxy-phenolic anti-corrosion layer, non-reactive with hardware anti-rust paints, acrylic coatings, and solvent-based finishes. It prevents chemical reactions between the tinplate and paint that cause sedimentation and deterioration. The can mouth is sealed with a high-density nitrile rubber gasket + crimped lock ring, achieving 100% leak-proof performance even under high-pressure filling (≥2.5MPa) and rapid assembly line transfers.
Durable Lightweight Structure for Bulk Workshop Use
Constructed from 0.22mm high-strength tinplate with reinforced edge rolling technology, the can resists extrusion, impact, and deformation during bulk handling and stacking in hardware factories. It supports high-speed automated filling and capping on production lines, matching the efficiency of large-scale hardware manufacturing. The non-slip ribbed surface ensures a firm grip during manual spraying, avoiding accidental drops and packaging damage.
