Bostik® 70-01A Silyl Modified Polymer Sealant (ISR 70-01)

Bostik® 70-01A, also known as ISR 70-01, is a high-performance silyl modified polymer (SMP) sealant engineered for durable, flexible, and long-lasting bonding and sealing. Designed for demanding industrial, transportation, construction, and marine applications, it provides strong primerless adhesion to a wide range of substrates.

• High-strength SMP sealant for industrial and construction use
• Primerless adhesion to metals, composites, plastics, and coated surfaces
• Flexible, vibration-resistant bond suitable for dynamic applications
• UV-, moisture-, and weather-resistant for interior and exterior environments
• Solvent-free, isocyanate-free, and low-VOC formulation
• Paintable after curing for seamless finishing

Bostik® 70-01A / ISR 70-01 is formulated for applications requiring high durability, elastic movement capability, and long-term environmental stability. Its advanced SMP technology creates strong, flexible bonds that withstand vibration, thermal expansion, and challenging weather conditions. Ideal for vehicle assembly, RV and marine construction, building components, architectural panel bonding, industrial OEM manufacturing, and general sealing tasks, this versatile sealant cures to a tough, elastic joint that resists UV degradation, moisture penetration, and mechanical stress. With a smooth, easy-to-tool consistency and non-shrinking formula, 70-01A provides clean, reliable performance in both field and production settings.
