Bostik® 70-08A Silyl Modified Polymer Sealant (ISR 70-08)

Bostik® 70-08A, also known as ISR 70-08, is a high-performance silyl modified polymer (SMP) sealant engineered for demanding bonding and sealing applications in transportation, marine, construction, and industrial manufacturing. Its hybrid formulation delivers strong primerless adhesion, long-term durability, and exceptional flexibility.

  • High-strength SMP sealant for industrial, marine, and construction use
  • Excellent primerless adhesion to metals, composites, plastics, and coated surfaces
  • Flexible, durable, and resistant to vibration, movement, and impact
  • UV-, weather-, and moisture-resistant for long-lasting outdoor performance
  • Solvent-free, isocyanate-free, and low-VOC for safer application
  • Paintable after curing for a clean, professional finish

Designed for structural and elastic bonding, Bostik® 70-08A / ISR 70-08 provides outstanding performance in applications requiring strength, movement capability, and long-term environmental resistance. Its advanced SMP chemistry ensures strong primerless adhesion to aluminum, coated and painted metals, fiberglass, plastics, and composite assemblies, making it a preferred choice for trailer construction, automotive and truck body fabrication, RV and marine manufacturing, architectural panel bonding, and industrial sealing tasks. The cured sealant forms a tough, flexible elastomer that withstands temperature cycling, vibration, moisture exposure, and harsh weather conditions while maintaining excellent bond stability. With smooth tooling, low odor, and no shrinkage, 70-08A offers consistent, professional results in every application.
