Bostik Simson ISR 70-05AP

High-strength elastic adhesive for structural bonding with improved adhesion

Advanced elastic adhesive and sealant for durable structural bonding applications.

Bostik Simson ISR 70-05AP Elastic Adhesive & Sealant is a high-performance, moisture-curing adhesive designed for demanding bonding and sealing applications where flexibility, strength and long-term durability are essential. The AP formulation offers enhanced adhesion properties, making it suitable for a wide range of substrates including metals, composites, plastics, painted surfaces and timber, often without the need for primers. Once cured, ISR 70-05AP forms a strong yet elastic bond that absorbs vibration, movement and shock, helping maintain joint integrity in dynamic environments. Key benefits include high mechanical strength, excellent elasticity and resistance to ageing, weathering and environmental exposure. Compared to rigid adhesives, ISR 70-05AP reduces stress concentration and minimises the risk of bond failure due to movement. It is widely used in transport, marine, construction, manufacturing and industrial maintenance applications where reliable elastic bonding and sealing performance is critical.
