BUYAN Self-Sealing Coating is an advanced ballistic protection and fuel containment solution developed for military, aerospace, and high-risk operational platforms.

The system is engineered to instantaneously seal penetration holes caused by ballistic threats, preventing fuel leakage, fire ignition, and secondary damage.

Unlike conventional armor-based protection methods, BUYAN focuses on sealing the threat rather than blocking it, enabling significant weight reduction while maintaining high survivability.

Features

The coating can be applied to metal or composite fuel tanks, fuel piping systems, and mobile fuel carriers, making it suitable for both land and airborne platforms, including helicopters and tactical UAV support systems.

BUYAN has been ballistically tested with 7.62 mm ammunition and validated under MIL-STD-810G environmental conditions, demonstrating reliable performance under extreme temperature, humidity, and salt fog exposure.

  • Instantaneous Self-Sealing Capability
    Automatically seals entry and exit holes immediately after ballistic penetration, minimizing fuel loss and fire risk.
  • Ballistic Protection Performance
    Tested against 7.62 mm caliber threats, with protection levels aligned to STANAG 4569 Level III.
  • Weight-Efficient Protection Concept
    Eliminates the need for heavy armored steel plates, providing up to 80% weight savings compared to traditional armor solutions.
  • Multi-Surface Applicability
    Compatible with steel, aluminum, polymer, and composite structures.
  • Fuel & Chemical Resistance
    Resistant to hydrocarbons, aviation fuels, and operational chemicals.
  • Environmental Durability
    Fully compliant with MIL-STD-810G for high temperature, low temperature, humidity, and salt fog conditions.
  • Corrosion & Abrasion Protection
    Enhances structural integrity and extends service life of fuel systems.
  • Vacuum-Assisted Bonding Process
    Ensures homogeneous adhesion and long-term sealing performance.
