DOWSIL™ 7091 Adhesive Sealant White (20 LT)

Product Overview

DOWSIL™ 7091 Adhesive Sealant White is a 1-part, neutral-cure room temperature vulcanizing (RTV) silicone adhesive designed for applications requiring a strong yet flexible bond. It provides excellent unprimed adhesion to a wide variety of substrates including metals, plastics, glass, and ceramics. Its white color provides a clean, aesthetic finish for light-colored industrial assemblies and lighting applications.

Key Features and Benefits

• Unprimed Adhesion: Excellent primerless bonding to metals, glass, ceramics, and engineering plastics.
• Non-Corrosive Neutral Cure: Odorless alkoxy cure system that will not corrode sensitive metals.
• Wide Temperature Range: Maintains performance and elasticity from -55°C to +180°C.
• Weather & UV Resistance: Superior durability against UV radiation, ozone, moisture, and weathering.
• High Elasticity: Absorbs mechanical stress and differential thermal expansion in dynamic joints.
