Product Data Sheet

Sikasil® AS-70 is a one-component, neutral-curing silicone adhesive engineered for demanding industrial bonding and sealing applications where long-term durability, flexibility, and environmental resistance are critical. Combining high mechanical strength with excellent elongation properties, this versatile adhesive delivers durable elastic bonds across a wide variety of substrates and industrial assembly processes.

Designed for professional manufacturing and industrial environments, Sikasil® AS-70 bonds exceptionally well to glass, metals, coated metals, plastics, ceramics, and wood. Its moisture-curing silicone chemistry creates flexible, weather-resistant bonds capable of withstanding thermal expansion, vibration, and dynamic movement while maintaining strong adhesion over time.

The adhesive provides outstanding UV stability and weathering resistance, making it suitable for both interior and exterior applications exposed to harsh environmental conditions. Its superior heat resistance allows the cured material to perform reliably across a broad temperature range, including elevated operating temperatures commonly encountered in industrial manufacturing, solar, lighting, and transportation assemblies.

Sikasil® AS-70 features a non-sag consistency for clean, controlled application on vertical and horizontal surfaces using manual, pneumatic, electric, or automated dispensing systems. Its durable silicone formulation offers long service life and dependable performance in applications where flexibility and environmental resistance are essential.

The product is commonly used in industrial assembly, photovoltaic systems, headlamp bonding, exterior sealing, and other manufacturing applications requiring strong adhesion combined with excellent UV resistance and thermal stability.
