DOWSIL™ 7091 is a High-Performance, one-component, neutral cure Silicone adhesive/sealant designed for applications demanding a strong yet flexible bond. It cures at room temperature upon exposure to atmospheric moisture, forming a tough, flexible rubber with excellent unprimed adhesion to a wide range of substrates.
Key Features & Benefits:- High Performance & Flexibility: Cures to a durable, flexible rubber that accommodates stress and differential thermal expansion.
- Wide Thermal Stability: Remains stable and flexible across temperatures ranging from -40°C to +180°C (-40°F to +356°F). Easy Application: One-component, non-sag paste consistency makes it straightforward to tool and apply.
- Broad Adhesion Profile: Achieves strong unprimed adhesion to enamelled/painted steel, aluminum, ceramic, glass, and engineering plastics (such as ABS, polycarbonate, and corona or plasma treated polyolefine plastics).
Applications- Dissimilar Material Bonding: Ideal for bonding materials with differing thermal expansion rates, such as glass-to-metal or glass-to-plastic. Gasketing: Functions as a reliable Formed-in-Place Gasket (FIPG) material.
- Industrial Assembly: General industrial bonding and sealing where flexible, high-strength adhesion is required.
