High-performance elastic adhesive for structural bonding and sealing

High-strength elastic adhesive and sealant for durable structural bonding.

Bostik Simson ISR 70-03 Elastic Adhesive and Sealant is a high-performance, moisture-curing adhesive formulated for demanding bonding and sealing applications where flexibility, strength and durability are required. It provides excellent adhesion to a wide range of substrates including metals, composites, plastics, painted surfaces and timber without the need for primers in many applications. The elastic formulation absorbs vibration, shock and movement, helping maintain bond integrity over time in dynamic environments. Key benefits include high mechanical strength, long-term elasticity and resistance to weathering and ageing. Compared to rigid adhesives, ISR 70-03 offers improved stress distribution and reduced risk of bond failure caused by movement. It is widely used in transport, marine, construction, manufacturing and industrial maintenance applications where strong yet flexible bonding and sealing is critical for performance and reliability.
