Total Available Stock: 317
PPG PR1828 Class B Rapid Curing Fuel Tank Sealant (1-Semkit 654) is a fast-curing aviation-grade sealant designed for use in aircraft integral fuel tanks and fuselage sealing applications. It delivers excellent adhesion, flexibility, and resistance to aviation fuels (jet fuel and avgas) across a wide service temperature range.
Qualified to AMS 3277J, Type 2, Class B-1/2, Grade 1, PPG PR1828B-1/2 offers a working life of approximately 15 minutes at 25°C (77°F), making it ideal for rapid assembly, small-scale repairs, and fast-turnaround maintenance operations.
Information
Additional Product Information
Overview
PPG PR1828 Class B is a rapid-curing, epoxy-cured aviation sealant formulated for aircraft integral fuel tanks and critical fuselage sealing applications. It is engineered to perform in extreme operating environments, with a service temperature range from -62°C (-80°F) to 160°C (320°F) and intermittent exposure up to 216°C (420°F).
Key Features & Benefits
- Rapid-curing formulation: Approximately 15-minute application life for fast turnaround.
- Excellent fuel resistance: Maintains elastomeric properties when exposed to jet fuel and avgas.
- Wide service temperature range: Reliable performance from extreme cold to high heat.
- Superior adhesion: Bonds effectively to aluminum, composites, and common aircraft substrates.
- Low-sag, thixotropic paste: Ideal for fillet sealing, vertical, and overhead applications.
- Humidity-insensitive cure: Cures reliably in varied environmental conditions.
Applications
PPG PR1828B-1/2 is commonly used for fillet sealing of aircraft integral fuel tanks, fuselage seams, and other critical structural areas where fuel resistance and rapid cure are essential.
It is widely specified by aircraft OEMs, MRO facilities, and operators seeking to reduce downtime while maintaining high sealing integrity and long-term durability.
