Technical Product Information

DOWSIL™ 6-1104 Controlled Volatility Sealant White 142 G

Product Overview

DOWSIL™ 6-1104 Controlled Volatility Sealant White is a high-purity, 1-part, non-slump, neutral alkoxy-cure room temperature vulcanizing (RTV) silicone adhesive and sealant specially engineered for aerospace, spaceflight, optics, and sensitive electronic applications. Its controlled low-outgassing properties prevent fogging and contamination of optical components and sensitive surfaces in vacuum environments. Curing at room temperature upon exposure to atmospheric moisture, it forms a tough, flexible, white silicone rubber joint. The 142 gram tube format enables precise hand-application for critical assembly tasks.

Key Features and Benefits

• Controlled Volatility / Low Outgassing: Strictly limits volatile condensable materials under vacuum and space flight conditions to safeguard optics and electronics.
• NASA / ESA Outgassing Standards: Formulated to meet rigorous industry standards for low Total Mass Loss (TML) and Collected Volatile Condensable Material (CVCM).
• Non-Corrosive Neutral Cure: Safe for sensitive electronics, copper, silver, and aerospace metallic alloys.
• Non-Slump Paste: Easily maintains shape on vertical or complex geometries without sagging.
• Wide Operating Temperature: Retains elasticity and physical properties from -55°C to +200°C (-67°F to +392°F).
• Unprimed Adhesion: Excellent unprimed bonding to metals, glass, ceramics, and rigid aerospace substrates.
