Advantages of Silicone Sealants

XIAMETER® brand sealants have many advantages:

  • Outperform and outlast organic weatherproofing sealants
  • Greater UV stability, temperature and weather resistance than organic sealants
  • Are inherently waterproof
  • Remain flexible over a wide temperature range so are easy to apply in cold weather
  • Last longer and need to be replaced less often than many organic sealants, which reduces lifetime costs and contributes to sustainability


Composition of Silicone Sealants

XIAMETER® silicone sealants are mixtures of silicone polymers, fillers and crosslinkers. These one-part compounds are room temperature vulcanizing (RTV), meaning they cure at room temperature.

XIAMETER silicone sealant subgroups

  • XIAMETER® acetoxy sealants

    Acetoxy sealants offer good adhesion and resistance to ozone, UV radiation and temperature extremes. So they’re tough enough for sealing showers, sinks, and whirlpools, as well as industrial sealing and bonding in a range of other markets.

  • XIAMETER® alkoxy sealants

    These ready-to-use sealants offer a neutral cure, meaning they can be used on sensitive substrates. They also have a low odor and can be used in geographic regions where the use of oxime sealants is restricted.

  • XIAMETER® oxime sealants

    Oxime sealants cure to a tough, flexible elastomer that’s non-acidic, allowing compatibility with a variety of substrates. They can be put to use in a range of jobs such as sealing window and door frames, skylights, gutters, vents and pipes.

  • XIAMETER® silicone sealant polymers

    Silicone sealant polymers offer a very low Tg (low-temperature pour point), as well as resistance to high temperatures, oxidation, UV and some chemicals. Combined with their exceptional flow properties, this makes them ideal as a base material for the formulation of sealants and rubbers. XIAMETER® silicone sealant polymers come in a wide range of viscosities.
