BOSTIK 70-01A

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
