Key Features:

  • Bostik Simson ISR 70-05AP combines the advantages of desired properties of structural sealants including polyurethanes. Simson ISR 70-05AP is not reliant on the primed system to provide a cross-linking covalent bond (less changes of applicator error).
  • Bostik Simson 70-05AP adheres well without black glass primer on glass and no UV resistant primer is needed when the glass adhesive interface is adequately UV-protected by a ceramic coating. 
  • Solvent, isocyanate and PVC free.
  • Very good UV-resistance and ageing properties.
  • In general good adhesion on several substrates without the use of a primer.
  • Permanent elastic within temperatures from –40°C till +120°C.
  • Neutral, odourless and fast curing.
  • Paint compatible with most industrial paint- or lacquer systems, both alkyd resin and dispersion based (due to the large scale of different types of industrial paints a paint compatibility test is recommended).
  • Paintable after skin forming (wet on wet); this will not influence the curing speed.
