Technical Product Data

DOWSIL™ 7091 Adhesive Sealant Black (20 LT) – One-Part Neutral RTV Silicone Adhesive & Sealant

Product Description

DOWSIL™ 7091 Adhesive Sealant Black is a high-performance, one-part, neutral alkoxy moisture-curing (RTV) silicone adhesive designed for applications requiring a strong but flexible bond. It provides unprimed adhesion to commonly used materials including enameled and painted steel, aluminum, ceramic, glass, and many engineering plastics.

Key Features

• Cure Type: One-part, non-corrosive neutral alkoxy RTV cure (no mixing required)
• Unprimed Adhesion: Primerless bonding to metals, glass, ceramics, and most plastics
• Consistency: Non-slump paste consistency
• Hardness & Flexibility: 37 Shore A (Cures to a tough, flexible rubber)
• Temperature Range: Wide operating thermal stability from -55°C to +180°C
• Electrical Insulation: High dielectric strength for electrical component sealing
• Color: Black

Applications

• Formed-in-place gasketing (FIPG) for industrial machinery, flanges, and enclosures
• Structural bonding and sealing in automotive, rail, appliances, and HVAC equipment
• Sealing LED lighting fixtures, solar panel frames, and electrical junction boxes
• Dispensing via automated equipment or industrial bulk pumps in high-volume assembly lines

Key Advantages

• 20 Liter bulk pail container maximizes production efficiency for automated line integration
• Non-corrosive neutral cure system safe for copper, brass, and delicate electronics
• Offers high elongation and tensile strength to absorb mechanical shock and differential thermal expansion
• Outstanding resistance to weathering, UV radiation, moisture, and temperature extremes

Application Note: Substrates should be clean, dry, and free of oil or grease prior to sealant application. Cure rate depends on ambient humidity and temperature.
