Aircraft fuel tank, fuselage, windshield, conductive and specialty sealants
Industrial sealants and adhesives

For more than 50 years, PPG Aerospace – PRC-DeSoto has been a leader in the development of products fundamental to aerospace manufacturing, maintenance, and repair. That leadership is firmly established in the highly specialized field of aerospace sealants.

PPG Aerospace has completed qualification of all three grades of its non-chromate corrosion-inhibiting sealant PR-2870 that provides commercial, general aviation and military aircraft manufacturers as well as maintenance, repair and overhaul shops with faster cure to reduce application cycle time for significant cost savings.

PRC® aerospace sealants were the first products capable of resisting deterioration from long-term exposure to jet fuel. Since then, sealants such as PR-1422  and Pro-Seal™ 890  have become acknowledged industry standards for sealing fuel tanks.

This tradition of leadership continues with innovative new sealants based on our advanced Permapol® polymers. These sealants are lighter in weight, withstand higher temperatures, cure faster, and are easier to apply.

Now enhanced with Sealants Europe SAS formed from acquiring majority interest in the aerospace and automotive sealants and adhesives business of Le Joint Français (LJF).

Supported by a global network of Application Support Centers, each staffed by technical support specialists who can quickly provide needed service and information, PPG Aerospace – PRC-DeSoto continues to establish higher standards for products and service excellence.

We're at work in a variety of aerospace sealant applications

Adhesion Promoters

Application Guides
Sealant Application Guides

Corrosion Inhibitive Sealants
Corrosion Inhibitive sealants will act as an effective barrier against the common causes of corrosion on aluminum alloys or between dissimilar metals.

Customized Sealant Solutions (CSS)
A family of products designed to simplify the sealing process.

Electrical Potting / Molding
PRC polyurethane potting and molding materials are designed for potting electrical connectors and/or molding electrical cable assemblies. These polyurethane compounds are suitable where high dielectric, high abrasion, flexibility, high tensile strength, and excellent hydrolytic stability are required.

Electrically Conductive
These cured sealants maintain electrical continuity in aircraft applications.

Fast Cure / Flight Line Repair
These sealants are rapid cure, aircraft integral fuel tank and fuselage sealant. The cured sealant maintains excellent elastomeric properties after prolonged exposure to both jet fuel and aviation gas.

Fuel Tank / High Performance Options
Expanding the performance envelope in areas such as higher strength, temperature range and weight reduction.

Fuel Tank / Proven Standards
The cured sealant maintains excellent elastomeric properties after prolonged exposure to both jet fuel and aviation gas. It cures at room temperature to form a resilient sealant having excellent adhesion to common aircraft substrates.

High Temperature and Firewall
The material is designed for sealing firewall structures against the passage of air and vapors.
