Naftoseal® polysulphide aircraft sealants for OEMs and maintenance are specifically designed to meet the technological requirements of the aerospace industry. Benefit from a full range of approved, easy-to-use, eco-friendly sealants and sealant removers.

Our sealants offer you eco-friendly properties: all components are chromate-free, solvent-free or very low in solvent content. The application characteristics boast good thixotropic properties (no slump), fast tack-free and cure rates to enable higher production rates.

These advantages of our Naftoseal® sealants are even further enhanced by low-temperature flexibility, good adhesion to various substrates and an excellent resistance to numerous aerospace chemicals.


Adhesion promoters

Naftoseal® adhesion promoters enable you to achieve secure, good adhesion, even if you work with difficult substrates. Besides the improved adhesion quality, our one-component adhesion promoters offer numerous other advantages, like easy application and high flashpoints (> 30 °C), to name but a few.


MCI mixer – simply good

The MCI sealant cartridge mixer solves all problems that might occur with manual mixing: it ensures excellent, consistent sealant mix without air intrusion. As it is air driven, it can be operated close to the point of use of the sealant and, if necessary, in flame-proof areas. For more please view our MCI mixer film.
