Sealants

The sealants application plays a critical role in the safety of aircrafts. The specialized materials are used to seal joints and gaps in various components of an aircraft to prevent the ingress of fluids, gases, and moisture. The polymer-based Naftoseal^® sealants are designed to meet the challenging technological requirements for overcoat, fillet, and interfay applications during aircraft production, assembly, and maintenance.  To complement this portfolio, we also offer adhesion promoters, sealants removers, and MC-Injection Mixers, all designed to enhance application precision and ease of use. 

In addition to strong adhesion on various substrates and excellent resistance to aviation fuels, oils, and numerous other chemicals, Naftoseal polysulfide aircraft sealants provide excellent protection of aircraft components from corrosion. Our solutions are all chrome-free, and due to their low density, they contribute to the overall weight reduction of aircraft, offering sustainable benefits. Our advanced sealant technologies streamline application processes while ensuring durability, efficiency, and environmental responsibility. 

Naftoseal adhesion promoters ensure secure bonding, even on challenging surfaces, while offering easy application and high flashpoints for added safety. The MC-Injection mixer further optimizes efficiency by delivering a consistent, air-free sealant mix, ensuring precision and reliability––even in flame-proof areas. Sealants removers are specifically formulated to dissolve Naftoseal and other polysulfide sealants used in the aircraft industry. They remove semi- and fully cured sealants from mixing and application equipment. 

With major OEM approvals and maintenance certifications, Naftoseal offers cutting-edge sealant solutions to optimize your aerospace applications.
