Momentive Performance Materials IS808 One-Component, Paste Consistency Silicone Rubber Adhesive Sealant, Translucent
Categories: Polymer; Adhesive; Thermoset; Silicone; Silicone, RTV, Adhesive/Sealant Grade

Material Notes: IS800 series one-component, ready-to-use silicone adhesive sealants have a paste-like consistency and cure to silicone rubber on exposure to atmospheric moisture at room temperature. Because these paste-consistency products will flow only with external pressure, they may be applied to horizontal, vertical, and overhead surfaces in thicknesses up to 6mm (1/4 in.). They have sufficient uncured body to adhere to small objects while cure is taking place.

ISO800 Series adhesives utilize a moisture vapor cure system and release acetic acid vapors from the sealant surface as a by-product of cure.

Key Performance Properties:

  • One-component product
  • Thixotropic (paste-like) consistency
  • Capability to cure at room temperature and ambient humidity conditions
  • Excellent electrical insulation properties
  • Excellent weatherability and ozone and chemical resistance
  • Self-adhesion properties
  • Low temperature flexibility
  • High temperature performance


The paste-consistency of these adhesive sealants make these products ideally suited for application to vertical and overhead surfaces where use of pourable self-leveling sealants would not be practical. These sealants may be sued in thicknesses up to 6mm (1/4 in.) for bonding and sealing, joining metals and plastics, and electrical insulation.

These sealants are not for use in delicate electrical and electronic applications in which corrosion of copper, brass, or other sensitive metals is undesirable.

All IS800 series sealants are identical materials, differing only in color.
