PPG Aerospace Mastinox CA 1000 Non-Chromate Corrosion Inhibitive Jointing Compound

PPG Mastinox CA 1000 is a high-performance, non-chromate corrosion inhibitive jointing compound designed for the protection of aircraft structures. As an eco-friendly alternative to traditional strontium chromate products, CA 1000 remains permanently flexible and chemically stable across a wide temperature range. It is specifically formulated to act as a barrier between dissimilar metals, preventing galvanic corrosion in joints, fasteners, and faying surfaces without the environmental or health hazards of heavy metals.

Key Benefits

• Non-Chromate Formula: Fully compliant with modern health and safety regulations (REACH compliant) while maintaining superior anti-corrosive properties.
  
• Permanent Flexibility: Does not harden or become brittle with age, allowing it to absorb the structural flex and thermal expansion/contraction of aircraft skins.
  
• Dissimilar Metal Protection: Creates a high-resistance barrier that prevents the electrochemical reactions (galvanic corrosion) typically found between aluminum and stainless steel or titanium fasteners.
  
• Excellent Fluid Resistance: Highly resistant to aviation fuels, hydraulic fluids (Skydrol), and water washout.
  
• Ease of Maintenance: Because it remains a non-curing paste, fasteners treated with CA 1000 can be easily removed and inspected without damaging the surrounding structure.

Applications

• Fastener Installation: Used for "wet-installing" rivets, bolts, and screws into airframe structures to seal out moisture.
  
• Faying Surfaces: Applied between overlapping metal skins or structural members to prevent intergranular corrosion.
  
• Dissimilar Metal Joints: Essential for interfaces where steel, titanium, or carbon fiber components meet aluminum structures.
  
• Removable Access Panels: Ideal for panels that require frequent removal but need a watertight, corrosion-proof seal.

The industry standard for "green" (non-chromated) jointing in modern aircraft production.

• Airbus: AIMS 04-05-005
• Textron Aviation: Part number CA1000 (standard for Beechcraft, Cessna, Hawker)
• Boeing: BMS 3-27 (Equivalent performance; often used as a non-chromate alternative)
• SAE International: Tested to AS5127 (Standard Test Methods for Sealants)
