BOSTIK 70-01A
Harmonization Code : 3919.10.80 | Other self-adhesive plastic rolls not exceeding 20 cm wide.
Main features
- Permanently Elastic SMP Sealant with Temperature Resistance
- Primerless Glass-to-Metal Bonding
- Solvent-, Isocyanate-, and PVC-Free Formulation
Product Description
Bostik Simson ISR 70-01 is a one-component, moisture-curing sealant based on silyl-modified polymer technology. It forms a permanently elastic seal for industrial joints where movement, sound, or vibration must be accommodated. The solvent-, isocyanate-, and PVC-free formulation provides excellent UV and weather resistance, adheres to many clean substrates without primer, and remains elastic from -40°C to 100°C. It is paint-compatible with most industrial alkyd- and dispersion-based coating systems, subject to compatibility testing.
Key features
- Permanent elasticity: Remains elastic across a service-temperature range of -40°C to 100°C.
- Primerless adhesion on many substrates: Adheres to aluminum, stainless steel, galvanized steel, glass, PVC, polyester, and many coated surfaces when properly prepared.
- Industrial processing flexibility: Provides approximately 30 minutes of skin-forming and tooling time at 20°C and 50% relative humidity and can be painted after skin formation.
Applications / Suitable for
- Bus, caravan, train, and truck construction
- Air-conditioning equipment
- Aluminum airfreight containers
- Sound- and vibration-reducing sealing applications
