PPG PS870B-1/2 (100ml / 654-Semkit) - USA ONLY

Additional Product Information

Overview

P/S 870 Class B is a corrosion inhibitive sealant designed to protect aluminum alloys and dissimilar metals in the harsh environment of the aerospace industry. This robust sealant has a service temperature range from -65 F (-54 C) to 250 F (121 C), with the capability to withstand intermittent excursions up to 275 F (135 C). Its advanced formula creates a strong barrier against the common causes of corrosion, ensuring the longevity and safety of critical aircraft components.

Key Technical Specs

• Wide Temperature Range: Functions effectively from -65 F to 250 F, withstanding peaks up to 275 F.
• Corrosion Inhibitive: Protects against corrosion on aluminum alloys and between dissimilar metals.
• Durable and Resilient: Maintains elastomeric properties after exposure to aviation fuels.
• Easy Application: Thixotropic paste can be applied using an extrusion gun or spatula, curing at room temperature for strong adhesion to common aircraft substrates.

Typical Applications

• Sealing and protecting aircraft structures from corrosion
• Use in fuel tanks and fuselage seams exposed to jet fuel and aviation gas
• Areas prone to corrosion between dissimilar metals
• Maintenance and repair operations requiring dependable corrosion protection

Compatibility & Safety Notes

• Resilient across a broad temperature range, suitable for aerospace environments
• Maintains integrity after fuel exposure

Packaging & Procurement

• Typically supplied in extrusion gun cartridges or bulk packaging for application by maintenance teams
• Part / Kit size should be specified with purchase (e.g., cartridge, tube, etc.)

Why P/S 870 Class B is Chosen for AOG / MRO
