Av-DEC's Hi-TAK Tape®Hi-TAK StructureSeal®Hi-TAK®TufSeal®and StretchSeal® are pre-cured polyurethane tape sealants designed to seal and provide a moisture proof barrier between irregular surfaces. The ease of installation and removal of these tape products leads to a reduction in return-to-service time, troubleshooting time, labor costs and amount of time the aircraft is kept in the hanger for maintenance.

When the products are removed from the mating surface there is no residue left behind, eliminating the need for solvents, and scraping, while also avoiding paint adhesion issues. The non-hazardous polyurethane material also leaves no silicone oil residue before, during or after installation or removal.


Hi-TAK StructureSeal®

 Hi-TAK StructureSeal® is Av-DEC's newest line of pre-cured polyurethane sealants for corrosion prevention of structural surfaces.  Each roll of Hi-TAK StructureSeal uses Av-DEC's proven sealant technology to prevent corrosion.  For sealing and moisture-proofing irregular surfaces, apply Hi-TAK StructureSeal under compression between two surfaces in applications where crush resistance or a mechanical stop is desired.  Common uses are under floor boards, lavatories, galleys, door sills and on top of stringers.  See the entire line-up of Hi-TAK StructureSeal products here.
