Strong Sealing Paint Spray Can 500ml for Industrial Coating

Key Features

1. Triple-Reinforced Strong Sealing System

    

   Equipped with a high-density fluorine rubber gasket + threaded anti-backflow cap + heat-sealed aluminum foil liner triple-seal structure for 100% leak-proof performance. It isolates air and moisture, prevents paint volatilization and oxidation during long-term storage (up to 36 months), and avoids leakage when inverted or under severe transportation vibration. It passes a 72-hour pressure immersion test with zero leakage, meeting strict industrial sealing requirements.
2. Industrial-Grade Anti-Corrosion Inner Coating

    

   The inner wall is coated with a high-adhesion epoxy-phenolic anti-corrosion layer that is non-reactive with solvent-based, water-based, epoxy, and anti-rust industrial coatings. It prevents chemical reactions between tinplate and paint causing discoloration, sedimentation, or deterioration, ensuring consistent industrial coating quality. The scratch-resistant and wear-resistant coating maintains protection even after repeated filling and cleaning for reusable scenarios.
3. Durable Structure for Industrial Environments

    

   Constructed from 0.28mm thickened high-strength tinplate with integrated stamping and reinforced edge rolling to resist extrusion, impact, and deformation in busy industrial workshops. It withstands filling pressure ≥3.0MPa, adapting to high-pressure filling requirements of industrial paints containing propellants. The non-slip ribbed surface ensures a firm grip and reduces hand fatigue during prolonged spraying.
4. Easy-to-Fill Design for Industrial Efficiency

    

   Compatible with most industrial filling nozzles and funnels. It enables quick, spill-free filling, reducing operation time by 25% compared to standard narrow-mouth cans. The wide mouth facilitates easy interior cleaning, supporting repeated use to save costs in industrial applications.
