Momentive Performance Materials RTV112 One Component Acetoxy Adhesive Sealant, White
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.

RTV 112 and 118 sealants are self-leveling products which are preferable to paste-consistency sealants when flow into small crevices and hard to reach places is desired.

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:

Electrical insulation, thin section potting, self leveling protective coatings. Will flow into small crevices and hard to reach places.
