P/N PPG PS870B-1/2 -1001 (100-ML-SEMKIT)

Product Overview

Introducing PPG PS870B-1/2 (100-ml-Semkit), the ultimate corrosion inhibitive sealant for aircraft. With a wide temperature range from -65°F to 250°F, it safeguards critical components against corrosion, even in harsh conditions. Easy to apply and with superior adhesion, it ensures longevity and reliability, making it indispensable for aircraft maintenance and manufacturing. Additional Product Information Overview This high-performance, corrosion-inhibitive sealant is designed for aerospace applications where long-term durability and environmental resistance are critical. It provides a protective barrier against moisture ingress and galvanic corrosion, particularly on aluminium alloys and between dissimilar metals commonly found in aircraft structures. Engineered for use in both manufacturing and MRO environments, the sealant maintains flexibility and adhesion under thermal cycling, vibration, and exposure to aviation fluids. Its formulation ensures reliable sealing performance in demanding operational conditions. Key Technical Specs Type: Corrosion-inhibitive aerospace sealant Service Temperature Range: -65 F to 250 F (-54 C to 121 C) Intermittent Temperature Resistance: Up to 275 F (135 C) Consistency: Thixotropic, low-sag formulation Application Method: Suitable for extrusion gun or spatula application Adhesion: Strong bonding to aluminium, composites, and dissimilar metals Approvals & Specifications Designed for aerospace structural sealing and corrosion protection applications Typically aligned with OEM aircraft sealing and corrosion prevention standards Typical Aircraft MRO / AOG Applications Sealing aircraft structural joints and fastener lines Corrosion protection between dissimilar metals Fuel tank and fuselage sealing applications Maintenance and repair of exposed structural areas Compatibility & Safety Notes Compatible with aluminium alloys, composites, and common aerospace substrates Provides protection against moisture ingress and galvanic corrosion Apply using appropriate PPE and follow standard aerospace sealant handling procedures Packaging & Procurement Available in cartridge or kit formats depending on application requirements Supports both small-scale repairs and larger structural sealing operations Why This Sealant is Chosen for AOG / MRO Reliable corrosion protection in harsh operating environments Maintains flexibility under vibration and thermal cycling Easy application with controlled, low-sag consistency Supports rapid response during AOG maintenance scenarios Practical Suggestions for Your Team (AOG Mindset) Ensure proper surface preparation to maximise adhesion and seal integrity Use extrusion tools for consistent application in structural joints Keep stock available for quick turnaround during maintenance operations Manufacture / Aviation Spec Codes Applicable to aerospace corrosion-inhibitive sealant specifications (OEM dependent) Alternative Names & Descriptions Aerospace corrosion-inhibiting sealant Aircraft structural sealing compound Galvanic corrosion protection sealant Flexible aircraft joint sealant
