Momentive RTV142 White Silicone Rubber Adhesive Sealant 5.4 oz Cartridge
Momentive RTV142 is a one-component, ready-to-use adhesive sealant that cures to a tough, durable, resilient silicone rubber on exposure to atmospheric moisture at room temperature.
- Product Type Adhesive Sealant
- Product Form Paste
RTV142 Series sealants utilize a moisture cure system and release methyl alcohol vapors from the sealant surface as a by-product of cure. These vapors have low odor and are non-corrosive to metals.
An important property of RTV142 Series sealants is their low volatility. Every batch meets the stringent standards of NASA's ASTM E595 for low outgassing. This sealant has a thixotropic paste consistency, allowing application in both vertical and overhead surface applications without sagging.
The material can also be diluted with solvents to create highly flowable materials.
- Room temperature cure
- Primerless adhesion to many substrates
- Low odor
- Non-corrosive to metals
- Low volatility, low outgassing meeting NASA ASTM E595
- Low temperature flexibility
- High temperature performance
- Excellent weather ability, ozone and chemical resistance
- Excellent electrical insulation properties
The non-corrosiveness to metals and low volatility of RTV142, as well as the paste consistency, makes it well suited for critical electronic adhesive, gasketing, weatherproofing and sealing applications where a high level of volatile condensable materials cannot be tolerated. This includes electronics, aerospace, satellites, spacecraft and defense applications.
