BOSTIK 70-07A
Harmonization Code : 3919.10.80 | Other self-adhesive plastic rolls not exceeding 20 cm wide.
Main features
- Adjustable Spray-Texture Application
- Elastic from -40 to 100 deg C
- Primerless Adhesion on Listed Substrates
Product Description
Bostik 70-07A is a single-component, sprayable SMP seam sealant for welded, overlap, and construction seams. The solvent-free material produces an adjustable spray structure, with application texture controlled through air pressure and nozzle setting, and is designed for sprayable repair and seam-sealing work. It develops adhesion to a documented set of metal, glass, PVC, polyester/GRP, and coated surfaces without primer, while untreated PE, PP, and PTFE are excluded. After cure, the sealant remains permanently elastic across a documented -40 to 100 deg C temperature range and can also be used for selected vibration-reducing coating applications.
Key features
- Adjustable Spray Texture: Air pressure and nozzle settings can be adjusted to produce rough or fine spray structure.
- Primerless Listed-Substrate Adhesion: Adheres to multiple documented metals, glass, PVC, polyester/GRP, and coated surfaces without primer.
- Elastic Cured Performance: The cured sealant remains permanently elastic across the documented -40 to 100 deg C range.
Applications
Sprayable sealing of welded, overlap, and construction seams; selected seam-repair and vibration-reducing coating applications within the documented process scope.
