Momentive Performance Materials RTV109 One Component Acetoxy Adhesive Sealant, Aluminum
Categories: Polymer; Adhesive; Thermoset; Silicone; Silicone, RTV, Adhesive/Sealant Grade

Material Notes: RTV series one-component, ready-to-use adhesive sealants are extremely versatile. They cure to a tough, durable, resilient silicone rubber on exposure to atmospheric moisture at room temperature. Acetic acid vapors are released from the sealant surface as a by-product of cure.

RTV102, RTV103, RTV108, and RTV109 sealants are standard strength paste consistency products which can be applied to vertical and overhead surfaces where pourable/self-leveling sealants are not practical.

Key Performance Properties:

  • One-component products
  • Capability to cure at room temperature and ambient humidity
  • Self adhesion properties
  • Low temperature flexibility
  • High temperature performance
  • Excellent weatherability and ozone and chemical resistance
  • Excellent electrical insulation properties

Applications:

General purpose bonding, sealing, electrical insulation, formed-in-place gaskets. Can be applied to vertical or overhead surfaces.
