Naftoseal

Superior sealant solutions are crucial for the aerospace industry because they ensure the integrity and safety of aircraft structures, contribute to fuel efficiency and enhance overall performance. Our Naftoseal technology portfolio consists of high- and low-density sealants designed for fuel tanks and fuselages, low-adhesion sealants specifically formulated for removable parts, gap fillers for floor panels, and adhesion promoters to improve bonding performance. Additionally, we provide seal caps and mixing equipment to effectively support your application needs. Our comprehensive range of solutions is tailored to meet the stringent demands of the aerospace sector, delivering reliable solutions that uphold the highest standards of quality and safety. 

Our Naftoseal sealants feature chromate-free, low-solvent and solvent-free formulations. They deliver superior environmental compatibility, and their application properties include excellent thixotropy with low slump, a fast tack-free time (TFT), and rapid curing, all of which enhance production efficiency. With a full range of approvals from major aircraft OEMs and maintenance providers, Naftoseal sealants offer unmatched reliability and compliance for aerospace applications. 

Naftoseal technology excels in performance, providing strong adhesion to various substrates, flexibility at low temperatures, and exceptional resistance to a wide range of aerospace chemicals. For challenging substrates, Naftoseal adhesion promoters ensure secure and reliable bonding. These one-component solutions are simple to apply and feature high flashpoints, combining safety and convenience.  

The MCI sealant cartridge mixer eliminates issues related to manual mixing by delivering consistent, air-free sealant preparation. Air-driven and safe for flame-proof areas, the MCI mixer ensures precise application close to the point of use.
